Preferred Solution: Cannot connect to internet by wireless: DHCP server details missing in ipconfig

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link (This link will automatically start a download of Reimage that you can save to your computer.)

Hi Guys,

I have been experiencing some irritating problems with my internet and creating a hosted network for my mobile devices. creating a hosted network was easy and has worked for quite some time until this weekend. Doing some quick google searches almost all the results said I should release then renew my ipconfig, and this is where all the real problems started. It won't renew and from there my problems keep coming.

My connection is provided by my university so there is no way for me to quickly reset the modem.

I would like to ask for help

I'm having a issue with the wireless in the past couple of days before it has always connected in seconds. when starting up the laptop it takes 1-2 minutes to connect (blue circle loading) but the connection is not stable such as random times disconnects (turns off itself) and the signal strength is pretty weak(looking at task manager 10-15mbps). Once the wireless stabilize which is around 15 minutes it can reach back to normal speed.

I went into the event viewer and noticed the laptop has this warning message + error message

Error message: The IP address lease for the network address 0x001D0981E03A has been denied by the DHCP server DHCP server sent a DHCPNACK message).

Another message:Router Advertisement settings have been changed on the network adapter 13. The current M - Managed Address Configuration flag is false and the O - Other Stateful Configuration flag is false. User Action: If you are seeing this event frequently, then it could be due to frequent change in M and O flag settings on the router in the network. Please contact your network administrator to have it resolved.

Answer:Wireless takes too long to connect (DHCP server)at startup?

My internet worked at home and I came to college and am unable to connect to the wireless interent. I poked around a while and realized that my computer was attempting to use a static IP, I removed that but still cant connect. ipconfig shows no default gateway.

Anyone have any idea?


Answer:Can't connect to wireless internet, ipconfig shows no default gateway

That is something you may need to speak to your Campus IT Dept. about.

I purchased a Netgear Push2TV PTV3000, and updated the firmware, downloaded the latest Intel WiDi, and tried to connect. The search for WiDi adapters found the PTV3000, so I double-clicked to install it. Add a Device ran, but could not find the PTV3000.
Searching the Web I found I needed to insure WiDiApp and Wireless PAN DHCP Server were allowed through the firewall. I found that the WiDiApp was listed in, and allowed through the firewall. I could not find any mention of Wireless PAN DHCP Server in the firewall.
I found the entry in Services, and it was listed as Manual. I set it to Automatic and tried to Start the service. I received an Error 1067: The process terminated unexpectedly.  I am running Windows 8 on a Sony SVS15118FXB.
As a possibly associated issue, since I believe Bluetooth also uses the Wireless PAN DHCP Server, I cannot get Bluetooth to function on the same computer. Attempts to connect Sony Bluetooth speakers also fail.  Maybe the same issue?
Any help would be most appreciated...

Answer:WiDi can't connect, found Wireless PAN DHCP Server can't start with error 1067

Basically I have followed some of the other problems on this site but I have yet to find a fix to my Ethernet issues. when I diagnose the problem it says Ethernet does not have valid up configuration. After a suggestion on another thread I did ipconfig/release then ipconfig/renew and it tells me unable to contact your dhcp server. Request has timed out. Thankyou in advance for the help

Answer:Ethernet won't connect ipconfig/renew unable to contact dhcp

Please provide more information in regards to what operating system you are using and the make/model of your PC. In addition, using TSG's Information Utility will be beneficial to us. Run the tool and provide the output in your next post.

Based off your commands, I'm assuming you're running Windows.
1. Hit the Windows key on your keyboard
2. Type cmd and hit Enter on your keyboard
3. In the black box that appears, type ipconfig /all > %userprofile%\desktop\ipcfg.txt and hit Enter

What this will do is create a text file on your desktop that includes all your configurations in regards to your network interfaces. Please copy the contents of that file and place them into your next message.

Also, please provide more information in regards to your setup.
1. Are you connecting wirelessly or with a cable?
2. Are other devices on the network connecting to the internet without issues?

Lastly, you have marked the thread as solved for some reason. Please undo this. If the issue is actually resolved, please share how you resolved it.

So I'm having an issue with my Ethernet connection. Here is the issue(s), and the steps I have already taken.


1 - I am connected to ethernet but have no internet access.

2 - Ran Diagnostics getting the error "Ethernet doesn't have a valid IP configuration"

3 - Went into admin CMD and typed ipconfig /release. Then ipconfig /renew.

4 - Received the error "Unable to connect to your DHCP Server. Request has timed out."

5 - DHCP service is running and automatic.


Here is the IP information from CMD:

Before continuing, this is a thread that I currently have going, if you want extra details on what's been going on. I'll try to explain it quickly here:

My laptop won't connect to wireless Internet. Doesn't matter where I am, so it's not a router problem.
I've tried many things (can be seen on the other thread), and still can't get wireless Internet connection.

Before I go any further, I'm not great with computers, so any instructions, please, eaassyyy!

Now the weird thing is, when I'm in Safe Mode with networking, Internet seems to be working fine!
As you can see in the title, my Ping test is showing something is wrong.

I have no idea what to do here. I've been going through forums, tried the following:

- Changing wireless channel
- TCP/IP stack repair options
- Calling Dell (what a joke that was...)
- ran an ipconfig /all (see on the other thread through my forum link)
- removed Mcafee (using Windows Essentials), and when I did that, Internet worked for 5-10mins then crashed again.
- checked the Mac filtering settings on my router settings

Also, my computer crashed the other day (got a blue screen, shut itself down). I posted the details in the thread.

Finally, my great friend the moderator Etaf asked me to post this to see if I have a problem that this forum could help me with ... I read the 1st post, here is the mentioned information (I couldn't do #3 because I run on 64-bit):

My daughter got a virus on her laptop and after getting rid of it (I think all the way, it's hard to tell until I can update the anti-virus software) I can no longer connect her laptop to the internet.

I have had a problem in the past with having to reboot the server and all the computers in order for the computers (all of them in the house) to register new ip addresses. Normally, if I have one computer that refuses to connect even after a reboot of the entire system I can connect it thru LAN and it, bang, fixes itself. However, this time it is not working.

Not only will her wireless not connect but neither will the LAN. I have opened the cmd prompt and done an ipconfig/release and ipconfig/renew. Every time I do this I get the message:

"An error occurred while renewing interface Wireless Connection : unable to contact your DHCP server. Request has timed out."

I tried the "netsh int ip reset resetlog.txt" and it seemed to work fine.

I also tried the "netsh winsock reset" and it seemed to work fine as well.

I rebooted each time I attempted a fix. Still I am unable to connect to the internet. It says it is connecting locally, but will not connect to the actual internet. When I use the repair option it gives me the same messages over and over that do not work. It always leads back to the IP address.

Here are the specs on her computer and as much information as I can think of. Please let me know what else I can try to get her compu... Read more

I just got Cox cable and it hasn't been working right.

I have a netgear WG602 wireless access point. I can connect to it but it has limited or no connectivity. Repairing the connection doesn't work and doesn't give me an IP.

I connected the ethernet cable directly to my laptop and it didn't work at all. I called them and it worked by directly connecting, but the wireless still didn't work.

Then I messed with wireless settings to try to connect, and I finally got online but my ip is 70.x.x.x, the apparent IP for all Cox subscribers.

But I got that 70.x.x.x through my router instead of a 192.x.x.x so I have no idea why it's doing that. It's really weird and I still can't get a dynamic IP.

Thanks for the help.

So here's the problem my PC say it cant connect to the DHCP-server (I tried both my router and connecting directly to my ISP and the result is the same)So what have I done so far to fix it?I have tried "ipconfig /release" and "ipconfig /renew"I have run different cleaning programs such as C-Clean and spybot.I have scanned it for viruses with McAfee.I have tried "netsh int ip reset C:\resetlog.txt" and it looked promising. After I ran it I had connection to my net. But after rebooting the PC I can't connect to the DHCP-server and "netsh int ip reset C:\resetlog.txt" does'nt work.So what happens?When I disconnect the UTP-cable the PC say "network no longer connected".When I connect the UTP-cable the PC say "connected at 1GB/s". But as I said I cant connect to the DHCP-server and if I try to type in an IP-address in the IPv4 config. I cant ping or connect to the other PC's in my LAN.So what can I do?I can ping get an 165.x.x.x IP-address.So anyone that can give a tip what's up with my PC and how I can fixit?

I am running windows xp on a dell inspiron 4150 with a built in wireless card. My wireless was working fine until windows prompted me to reboot due to windows update. It stopped working after that. It is telling me that no ip address can be found and when I ipconfiged it with renew and all it still could not find it. It gave me an error message that says cannot connect to DHCP server.
Any help will be appreciated.

Answer:Network could not connect to DHCP server

Nothing really comes to mind, but if you're using Window's Wireless Zero Configuration maybe you need to reconfigure your wireless connection; especially if your network is protected with encryption.

I use the utilities from my wireless cards' manufacturers to connect to my WPA protectecd network and had no trouble today after the same reboot (two notebooks). Well, same reboot if you're talking about the critical update released yesterday.

I got a new desktop loaded with Microsoft Vista.

When I couldn't connect to my router (at home) I tried ipconfig /renew /reliease commands and got the following message:

"Unable to contact your DHCP server".

I brought my PC to work and it connected fine to the network there.

At home I use the modem/router provided by Verizon (FIOS). I tried several ethernet cables - so I am pretty sure it is not the cable.

BTW, other pc's at home are connected to the router, so the router is OK.

Any help is appreciated.

Check the setting on your Router which served as your DHCP as well. Make sure that the Router provides enough IP addresses for your home network.

To Whom This May Concern:

I tried installing SP1 on a desktop Vista, with other windows updates, and my internet stopped working. My Xbox and another computer (XP SP2) work fine and haven't noticed a difference.

I've contacted my manufacturer, and they said uninstall everything. I did. There is one Windows Update and one Microsoft .NET Framework 3.5 SP1 that it won't let me uninstall. I've contacted my ISP and they said there's a problem between my modem and hub, but if that's the case, my other computers wouldn't be working either.

I've contacted Microsoft, several people, and after many procedures, concluded that I need a restore disk and set it back to factory settings. This is an absolute last resort.

Here are my specs:
Vista Home Premium
AVG 8.5
Comodo Firewall
XtremeGamer SoundCard
I don't know what else is important since the computer has worked for a year before attempting SP1

Here's what I've tried:
-ipconfig release, renew
-enable and disable dhcp broadcast flag via regedit
-exchanging cables, all cables work with other computers
-netsh resets
-clean startup tray
-closing viruscan and firewall, leaving one open, all possible combinations thereof
-power cycling the modem and hub

I'm using a Thinkpad Edge 11 and I just updated the BIOS utility (don't even know why i did that in the first place) using this link: I checked the BIOs version and it matches to my laptop (86ET31WW (1.15))  However now I cannot connect to the internet. I've tried troubleshooting my wireless connections and it tells me to switch on my 'wireless capability' on my laptop. I'm assuming that it's referring to a switch that can turn my wireless on and off but the laptop model that i have don't have that button at all.  I've installed the access connections program, but it also tells me to switch on a button on my laptop.  I've already checked my BIOS setup and the wireless shows that it's enabled there.  I have a feeling that I might have downloaded the wrong BIOS update but i don't know how to uninstall or undo it. Could someone please refer me to another BIOS update that i should use ? or any other method so i can turn my internet connection back on??? I am very inexperienced with computers... any help would be appreciated.  here are some additional information that might help about my laptop: windows 7 professional 64 bit Intel WiFi Link 1000 BGN  thanks in advance.

I'm using my home desktop to make this post. This is issue is with my Dell laptop that--up till an hour ago--had a wireless area connection icon in the lower right corner and a Wireless Area Network option when I went to "Network Connections" (I still have my LAN option.) I was using a Driver Whiz program to update all my drivers when it said I needed some Intel Wireless Config program. So I downloaded it but at the end I had no Internet access and no icon, etc. So I uninstalled that program but it was too late. I've even tried a system restore to a few hours prior to this mistake of mine to no avail. My husband says I need to connect hardwire to the Internet and download a WAN that correct?

Answer:Wireless Internet ipconfig/ all. Need Help

Welcome to the Seven Forums!

Hopefully you are not using Dell drivers for that Wireless adapter - they don't support W7 on the D630 (at least not that I saw).

According to the FAQ at this website:

What if I have the Intel? PROSet/Wireless WiFi Connection Utility installed on my PC that I am upgrading to Windows* 7?
You need to download and install the Intel PROSet/Wireless WiFi Connection Utility for Windows 7 after you upgrade the operating system.

Have you done that - or are you using the drivers that came with W7?

Iam working on a wireless extender where there is DHCP server.When I connect the repeater to my PC,initially I get the IP address which is assigned by the DHCP of the extender .Now when I connect the extender to a wireless router,my system gets the IP from the router and now the system Ip is IP assigned to the wireless extender by the router is
Now when I go and disable the DHCP server on the wireless extender,the page goes off and even ,the ping to the wireless extender fails with message saying "destination unreachable",but the internet works from the PC,as the PC is still connected to the extender and extender in turn connected to router.
My question is,as the router is assigning the IP to the wireless extender,why is that when the DHCP server is turned off,the extender cannot be accessed??Is this a bug or any other reason??

Answer:DHCP server behaviour on wireless extender

Turn DHCP off on the extender and allow DHCP server to assign addressess. The extender does not need an address it is transparent to devices.

I have had a network for almost two years with no problems, and for some reason my laptop has not been able to get online for about a week. It did this once before last year sometime, and I phoned Bellsouth; they said to shut down all the computers and then restart them, and that fixed the problem. It did not help this time.
I have tried everything I can think of.

My laptop is a Sony Viao with Windows 2000. I am using a Linksys router and wireless card with my Bellsouth Westell DSL modem. Someone else set up the network for me, but I don't have contact with that person any more to help me. I will probably phone Bellsouth again, but thought I'd try this, too. I tried Linksys' live chat but they kept getting disconnected.

When I type in ipconfig /release it says it's already released. When I type in ipconfig /renew it hangs a long time and then tells me that the DHCP server is unreachable.

I have three computers. One is this Dell I am currently typing on, with XP, and it is connected directly (wired) and works fine. Sometimes the connection goes out and I have to unplug the modem and plug it in again and then it works fine. That has always been true, though.

I have another Dell, an old one with Windows 98, and it is wireless. We don't use that one very much because it's slow, but it has a wireless connection and sometimes it can't get online, either. It has troubles but sometimes it works, sometimes it doesn't. That's been for ab... Read more

Thread title shows off most of my problems, whatever I do, I cannot use the internet, and it shows it off with a good old "Limited Connection" or "Limited Internet".
While troubleshooting in CMD Prompt, "ipconfig/release" responds with "error occurred while releasing interface Wireless Network Connection: The RPC server is unavailable."

You can skip simple things like "Open command prompt by searching...", on 10 just WINKey + X and then C or A to open it up, surprised most people are oblivious to this kind of thing.

Drivers are updated.

This all started whenever I found my desktop on with a blue screen, telling me about something needing repairs, because I know one of the buttons said "Repair" and the other was grey in color, perhaps "Cancel" or "Shutdown".
I just woke up and didn't know what I was doing really.
I found that my mouse needed to be unplugged and plugged back in to work correctly.

Please help me, I've been working on this all day, and others are perfectly fine, it my computer only that is having problems.
Please post your answers in bulk of what I can try to do, and what I should be telling you guys.

here's my setup:
-internet is through a westell 2200 DSL modem.
-Verizon gave us a static IP, gateway, dns, etc.
-modem is connected to a D-Link's DFL200. it's a router/fw/etc.
-i setup the D-Link's wan with static config provided by Verizon.
-i turn on DHCP server on the lan of the D-Link
-i have internet access.

the problem is that i want to enable the company network to be online as well. how do most people do it? i connected the D-Link's inside LAN to our network switch.

our network is w2k3-based AD/DHCP/DNS server serving about wxpp 20 clients. when i hook the D-Link to the network, none of the clients can get internet, but when i connect the D-link to a single client, i get internet. i've tried relaying DHCP server to our PDC (w2k3) but still no internet. is there a config i'm supposed to do on the D-Link or PDC that i'm missing?

how do people do it?

if i turn off DHCP completely, i get no internet connection from D-Link's inside LAN either through direction connection to a single client or through network. i guess these routers/firewalls require their internal DHCP to be on for internet to be enabled. that true?

i know a network can have more than 1 DHCP servers, but this one won't play nice? advice?

Answer:How do you reconcile your router/firewall's DHCP server w/your PDC's AD DHCP server?

actually, a network CANNOT have more than 1 DHCP server unless you configure different scopes on each one. if you have both managing the same leases you're going to double-book all your internal IPs and no one is going to get on the intarweb . . . . which you may have noticed is exactly what is going on here.

turn off the DHCP server on the DLink entirely. the reason your clients cannot access the internet using your windows DHCP server is because (my guess which i am 99% confident is correct) you did not set the scope options . . . specifically the one called gateway or router. this value should be set to the IP address of the DLink. it's the default route the clients will go to get to any other network other than the one they are part of.

Please supply the following info, exact make and models of the equipment please.

Name of your ISP (Internet Service Provider).
Make and exact model of the broadband modem.
Make and exact model and hardware version of the router (if a separate unit).
Model numbers can usually be obtained from the label on the device.
Connection type, wired or wireless.

If you're using a wireless connection, have you tried a direct connection with a cable to see if that changes the symptoms?
For wireless issues, have you disabled all encryption on the router to see if you can connect that way?
Have you connected directly to the broadband modem to see if this is a router or modem/ISP issue?
If there are other computers on the same network, are they experiencing the same issue, or do they function normally?

I have had wireless set up and working on my home system for more than a year. My laptop is configured to automatically switch between wired and wireless mode depending on whether I'm connected to an ethernet cable or not. I use comcast as my ISP, and have a netgear router. On Thursday (last week), I was working away connected wireless, when my network connection dropped. Tried to reconnect, and got the following message:

The DHCP server on this network failed to respond to the request your system made for automatic IP Address configuration.

I've tried everything I can think of to resolve this:
1. turned off and on the Comcast modem, disconnected the ethernet cable
2. reset the Netgear router
3. ran the /ipconfig release, renew, flush commands
4. unplugged everything from each other, (comcast, netgear), waited 30 seconds, re-connected everything

Nothing works. I'm currently connected via ethernet cable, so I know the connection is good, and this was after I flushed all the IP config information, so I know comcast served up a new IP via DHCP. It seems very strange to me that this happened out of the blue, while I was actually connected via wireless.. Any suggestions?

I found a couple of topics from google, but nothing gave me a very good answer to what I should do next, so I thought maybe it's best to ask the question directly:

Currently my internet isn't working (at a friend's house using his), and when I try to use ipconfig /release then /renew, it times out on me, saying: An error occured while renewing interface...: unable to contact your DHCP server. Request has timed out.

I tried using the XP Help and Support Center and ran a Network Diagnostics, and it failed getting n IP address for the DefaultIPGateway, DNSServerSearchOrder and DHCPServer. It did however manage to find my IP Address (...Huh??)

I've tried restarting the DNS and DHCP and rebooting the computers repeatedly, but nothing seems to have worked, and I seem to be out of ideas. Can anyone shed some light on this matter?

Thanks a bunch.

It would also be useful to know the make/model of the router, and whether it's a wireless or wired connection. Did you disable encryption if it's wireless to see if that gets it connected?

I can not connect to the internet after 3 days and probably 12-16 hours of trying. I recently had malware install on the computer, Stongvault to be specific. I uninstalled all the associated files, deleted the content from the program files directory, and then did a search for anything related to stongvault. I believe I have gotten rid of the malware, however, now I cannot connect online. It told me DHCP Error 1068. Among the many things I tried, I ended up deleting the line in the registry requiring other services to start before DHCP, and now DHCP starts. I can not however get AFD.sys to show up in the services. I've manually entered it into regedit in order to register it, and I verified that AFD.sys is indeed present in the system32\drivers folder. I've also tried driver updates and the like for the motherboard, as everything is onboard except for the graphics card on this machine. Any help would be appreciated.

I'm having issues connecting to the internet with my desktop computer through my wireless router (my laptop works just fine). If I connect LAN directly to my modem the IE works jsut fine, but if I connect WAN or LAN to the router I can't seem to get to the internet. The connection shows that it is connected in the network connections area, however. I've gone through the settings on my laptop and they match what I have on my desktop, so I'm lost as to where to go next. Is this a DHCP server issue?

Oh and the most frustrating part, is that on a fresh reboot, you can log right on and IE will work for one or two pages, and then the error page comes up. It also seems to be runing IE more slowly than it used to. I've run spybot and my norton and both are clean to see if it was virus related, but I'm just an ametur so any suggestions are appreciated!


Answer:Internet connection issue (DHCP server?)

So are you saying that when your desktop computer is connected to the router via network cable, your IE won't work? And if you connect the computer directly to the modem, IE works?

Since you have a wireless router your laptop works fine which is good. Hmmm...........on the desktop computer I would try to un-install IE and re-install it again and see if that helps. Also perform a windows update on that desktop computer.

I would also try to perform a windows repair and see if that helps as well.

i tried to setup my sbs 2003 for the first time this morning. Did not go so well.
I got stuck on networking, here is my config:

modem -> Linksys Router -> SBS ext nic | SBS | SBS int nic --> clients

I set my linksys router up as follows:
disabled NAT
forwarded all ports to the IP i assign the server (ext NIC)
PPOEE etc is all configured there
DHCP disabled

For my sbs, here is the config:
ext nic ("Network Connection"):
int nic ("Server Network Connection")

These are my setting coming into the wizard which sets the rest.
DHCP works, my clients connect to the int NIC,, they can ping eachother, but none can ping the server or access the net.

Am i missing something? I think im going to start from scratch tomorrow and see what happens. Is my configuration correct? When i tried to do http://mysbsname/configurecomputer (or w/e they tell you to do to join the server) nothing happens.

btw im running ISA.


Answer:Sbs 2003 - Dhcp Yes - Ping Server / Internet = No Help?

You've got the internal and external networks on the same subnet. That's not going to work.

The easiest and most reliable way of making this work is to ONLY use the Configure E-mail and Internet Connection Wizard at first. Most SBS installs with problems result from people trying to manually configure settings.

Work through the wizard, use for the external nic if that's what you want, use the default 192.16816.x subnet for the internal nic, and remember that you really should use the http://servername/connectcomputer if you want the clients to work properly.

Once everything is up and running you can play around with reconfiguring things. But for the first time installation, SBS is very particular about some things, so start with the defaults.

Okay, so I've been using my laptop online for about 2 years with no problems at all (Vista OS). Then one day I go to sign on and it doesn't "find" the network it has used for years. I fiddled around with the router, got a new encryption key and somehow it worked - for a short time. Now, nothing at all pertaining to the internet - only available to connect to a "local" network. I can access the internet when I use an ethernet cable only. Our desktop, iPod Touch and Mac have no problem connecting. The laptop and wireless printer are not picking anything up. From most that I have read it seems I should have a DHCP enabled - it says NO and I don't know how to fix it - I get error messages stating:

Cannot communicate with Primary DNS Server

Hi all, got back from the beach and was greeted with internet troubles.

My desktop is the problem, running Windows XP SP2 and I have already tried a number of things:

Running ipconfig gives me a 169.254.***.** address, which I understand is a private IP or something.

Clicking "repair" on the right click drop down box on my local area connection gives me: "Windows could not finish repairing the problem because the following action cannot be completed: Renewing your IP address."

ipconfig /release and ipconfig /renew gives me the following error:
"An error occurred while renewing interface Local Area Connection 4 : unable to contact your DHCP server. Request has timed out."

I have 2 other desktops and 2 laptops running on the exact same router, all are working like a charm. It appears to be something on the software side of my problematic desktop. I tried setting my IP manually by going to properties under Local Area Connection, then TCI/IP properties, but I don't know what to put as my DNS addresses. When I set my IP to what I know it SHOULD be and my default gateway to, my connection tells me everything is all right, but alas, no internet.

Any suggestions? And sorry if this is a repost, but the solutions for other people didn't work for me.

It was my understanding that all I have to do is set the Gateway of the dhcp to the ip address of the nic connected to the web, and client PCs would have Internet access. This however does not appear to be the case. What am I doing wrong?

Answer:Can't connect to Internet DHCP and renewing IP address issue

Are you using broadband? Wired or wireless?
If you're using a router and you know its IP address you can try manually giving an IP address to your PC but it has to be in the same range as your router. That is if your router's IP is then you'll have to specify something like to your PC.

You may want to try taking a look here too.

I hope you guys can help me, sorry this is very long and clueless. I am not techy at all.

I have 2 PC's connected via ethernet cable to a router provided by my ISP (Orange Livebox). One PC has Windows XP (hubby's) and one has Windows 7 (mine).

Until about 2 weeks ago both PC's were working fine and no internet connection problems. We lost our connection one Friday night along with thousands of other people in our area. It was fixed on Saturday but ever since then my PC has been dropping it's internet connection but my husband's PC is working normally.

My internet connection drops and will only come back on if I unplug the router and leave it off for a minute then plug it back in. Connection then works for a few hours (usually up to 7 or 8 hours) before dropping again.

I get this error in the Event Viewer when it happens:

"Your computer was not assigned an address from the network (by the DHCP server) for the network card with network address xxlong number herexx. the following error occurred: 0x79. Your computer will continue to try and obtain an address on it's own from the network address (DHCP) server."

Hello all, I was wondering if anyone can help me with my problem:

My sister's computer has decided to stop connecting to the internet since yesterday with the standard "Limited or No Connectivity" speech. We run 3 different laptops through the main computer's wireless network (which has the wired connection to the modem) and while the others are working fine, hers has the problem. Here are her specs:

Notebook: NEC Versa P8210
Notebook's Adapter: D-Link Wireless G DWA-110 USB Adapter
Modem: Belkin Wireless modem VoiP 802.11g gateway
Security: WEP (I tried changing it to WPA, but no computer could connect afterwards, so I switched back).
OPS: Windows XP Professional SP3

Things I have tried to do:

- enabled/disabled connection - no effect
- forced static IP address - This got me a full connection, but I couldn't ping or access the internet...?
- Ipconfig /flushdns, /release, /renew etc. - /renew get's stuck on "Unable to contact DHCP server"
- netsh winsock reset - no effect
- netsh int ip reset resetlog.txt - nothing happened
- restarting modem, computer, notebooks etc. - no effect
- checked & re-entered security key - no effect
- disabled firewall - no effect
Here's a copy of her ipconfig /all log:

hii alli had some problems with the dhcp concepts :what is single server / multiple server solution ?? and what's relay agent ?i hope someone can help me as soon as possiblethanx for your support

Answer:requestion about dhcp server, some questions about planning a dhcp to a network

Is this a homework task? You can just Google  "single server solutions" and get lots of info. Is that what you want? If you want to set up a server at home or school just to learn how it works, you need to talk to the people on the Linux forum. Linux is often used as a server on a desktop PC. At the present time many small companies single servers.

I'm not sure what techinal mumbo jumbo info you need, but I do know that you at least need that I have windows XP Service pack 3

The system restore is simple. I start it up, it runs, I log back in, and then I get a message without any error codes that it could not be compleated, and that no changes were made. When checking what is affected (since, when attempting a system restore, I get a message that says "Changes made to drive(s) E: after this point cannot be reversed because the drive was either excluded from System Restore monitoring, or was turned off or removed"

In any of the lists I find, it seems system restore only affects C: anyways.

I have a feeling that if I turn the restore points off then on, therefore reseting them, or create custome restore points, it would be fine, but I also have a feeling that a good system restore would fix my other, more complex problem. And if I can do a system restore in the end and fix this, I need those old restore points.

(Also, I have attempted system restore from various points from both normal and safe mode, and at no point was there a change in what happened.)

Just to be clear, the two issues stated in the title are related. (I read the rules and guidelines )

Last weekend, my Dell Inspiron E1505 laptop suddenly couldn't connect to the internet. I looked around every corner of the computer, checking to see if anything was corrupted/broken, and I found that the DHCP Client Service and DNS Client Service cannot start (Error 1608, the dependency service or group failed to start). The DHCP Client depends on AFD. NetBios over Tcpip (already started, so that's a green), and TCP/IP Protocol Driver. However, I cannot find the AFD service anywhere in Services, and the TCP/IP Protocol driver has a yellow exclamation mark next to it, same with the IP Network Address Translator driver. Their device status is Code 24 (This device is not present, is not working properly, or does not have all its drivers installed.), and when I try to start the IP Translator driver, it says "The system encountered the following error while attempting to start the service - The dependency service or group failed to start.". The TCP/IP driver gives me a slightly different error, "The dependency service does not exist or has been marked for deletion". Going back to regedit and looking in the Tcpip folder, the DependOnService data says IPSec. There's no IPSec folder in regedit, anywhere!

My laptop is running Vista SP2. The machine will connect to my Belkin router with a wired connection but I have a problem setting up a wireless connection. The machine can successfully obtain an IP address from the DHCP server but it is unable to get a ping response from the gateway address or anything else on the LAN (and yes, other devices on the LAN can ping the gateway I have tried stopping the Base Filtering Engine, running 'netsh winsock reset' and applying the fix in but none of these has resolved the problem.

In the 'Network and Sharing Center' window, the machine is shown as being connected to 'Unidentified network', but there is a red 'X' against the onward connection to the internet. Initially, I had the same problem with the wired connection but running 'netsh winsock reset' in the command window triggered it into creating a new network location the next time it connected and then it worked happily. Unfortunately, I have not been able to repeat this with the wireless connection.

The network adapter is an Atheros AR5007EG with driver version and the status show that is working properly. For information I have shown below the output from the command ipconfig /all:

Welcome to TSG.
We have seen quite a few issues with that adapter.
Here is a summary of things to try:
Courtesy of ETAF and Terrynet on the Networking Forum:
Atheros AR5007EG & AR5007
We have recently been seeing a lot of problems with the above adapters over the last few months, mainly concerning WPA and WPA2 encryption and windows Vista.

The adapter gets an IP configuration, and shows as connected, but communication is non-existent or sporadic.

Log into the Router and disable the wireless security and see if you are now able to connect to the internet and surf OK.
--- Please post back here if that works or does not work.

Here are a number of possible solutions

--- 1) In Device Manager right click on the wireless adapter and "update driver." That apparently has worked for some posters.

--- 2) Download and install the latest wireless driver from your laptop manufacturer's web site support section, as some manufactures, appear to now have a working driver available.

one of our NT guys just brought something to my attention.

out DHCP/DNS server has an interface on the production network, as well as a backup interface (backup network)

the backup network is a parallel network (physically seperated network hardware) and is not routed/connected to the production network. it is completely isolated for backups only.

i always make sure they do not put a gateway address on the backup network (there is no router, it's a flat network), so that no traffic accidentally goes out that interface

when they did a capture/trace on the backup NIC, they were seeing packets (DHCP ACKs/replies) from the production interface.

so say the routed / production IP of the DHCP server is

when you look at the trace on the backup interface, you are seeing the DHCP ACKs/replies from source:, destination

so it looks like the server is packaging the IP header / DHCP ACK as a layer3 broadcast, and thus sending it out every physical interface.

does anyone know why the server would be doing this, and not just sending out the DHCP ACK on the interface it received the request on?

Answer:DHCP server broadcasting DHCP acks out all interfaces?

Do you know the Server OS and DHCPD name and version (if not Windows)

I'm running a simple network at home with a Linksys BEFSR41 router. I have two computers hooked up wired and a wireless router acting like an access point that I use for my laptop occasionally. Until this weekend I've been having no problems but I shut down the computers due to weather and now one of them is not able to communicate with any others on the network. The problem computer will get an address supplied to it by the router (DHCP server) but once it has it I cannot get any other connectivity. Of course this is hindering internet access on this computer. I can ping the loopback and assigned IP addresses w/o problems but when I ping the default gateway (router) and/or the other computer I get "Request timed out." I initially thought it was the NIC so I bought another one but still get the same issue. I've moved the cards to different PCI slots but no luck. I tested the cable running from the computer and the router but found no problems. I even tried resetting the TCP/IP stack but still didn't work. The computer in question is running WinXP SP2 with the original NIC being a Linksys LNE100TX and the new one being a D-Link DFE-530TX+.

Any clues on this? If more info is needed let me know--it's been a while since I've posted. Thanks in advance.

Is it better to use Win2000 Server DHCP or DHCP from my Netgear wireless router?

I am currently in the process of setting up a Win2000 server on my home network which consists of four other 2000/XP machines.
The server is going to be configured as a domain controller and will utilize the Active Directory.

Should I use the Win2000 Server DHCP or stick with my wireless router as the DHCP server? What are the advantages/disadvantages to both and which would be easier to maintain.

Is a 550mhz PIII with 256MB RAM fast enough to make a good home server running Win2000 server?

The server is going to have (2) 120GB Western Digital 7200rpm drives with 8MB cache for storage and a single 60GB Western Digital 7200rpm drive for the OS and few other applications.

The server's primary function is to serve as a media server with an approaching 10GB of MP3 and music video files which is continually going to grow. Disk contention is at a minimum since there are only four PC's on the network. There will also be a lot of digital photos stored on the server and will also serve as a place to perform backups from the other four networked PC's.

Answer:Win2000 Server DHCP or Router DHCP?

We have a similar setup in our office using Small Business Server, a public IP coming into our router with DHCP turned on, connected to a NIC in the internal DHCP server (which is also running ISA). A second NIC in the server bridges to the internal hub to provide DHCP services to the clients. This way we control port filtering in 2 places and with 2 levels of NAT taking place we feel secure. It may be overkill but we're concerned that EVERYONE is trying to hack into ISA and DHCP servers connected directly to public IP that this setup provides an added level of security.

Info about my laptop:

HP Pavillion dv5-1000
Windows Vista SP2
Wireless a/g/n

Info about my network:

ISP: Optimum
The wireless network in our house is somewhat complicated, but is essentially:A modem which goes to a main router (ISP provided netgear)
That router broadcasts the network "NeroKingston"
One of the ethernet ports goes to a 24 port switch
2 more routers off of that (brand new from monoprice), used as WAPs
One in basement, one on main floor, one in attic

Every device one the network works (hardwired dvd player, Win7 machine, SONOS, android phones, macbooks, printers, iphones).

Info about my problem:

I will be connected to the network wirelessly and suddenly a page will take a very long time to load and finally says "cannot reach this page". If I try to do ipconfig /all (or maybe /renew, I forget) it says it is unable to contact my DHCP server.

If I disable and then re-enable the wireless adapter the problem resolves for a few more minutes, then dies out again.

When it is working my internet is realtively fast (30 megs up, 14 ms ping).

Hi everyone, I searched through the forums but couldn't really find what I was looking for.

Currently we have a DHCP server set up to a switch, that has a special line connecting to a switch in our shop which is just across our back lot, giving network access to the few computers over there. They recently put in a new machine that needs network access, but they have already accidentally cut two ethernet cords. I'm looking to provide a wireless solution for the machine, but I don't want to have to spend a few thousand dollars on a large wireless switch.

This morning my internet stopped working on my computer, and stays at "Limited or No Connectivity".

My computer is hooked up to a router with an ethernet cord, and that router is hooked up to my modem. There is also another computer hooked up by ethernet cord to the router, and I use the wifi a lot for my iPod. Both work fine, it's just the internet on my computer that doesn't seem to work.

So far I've ruled out any problems with the modem, router, ethernet cable and network card. I even went out and bought a new ethernet cable to see if that might fix the problem, but it didn't. Right now I'm in safe mode on my computer and the internet works fine, so the problem doesn't appear to be with my ethernet card.

I've tried unplugging and leaving both the router and modem for a few minutes, changing the cable to a different port on the router, hitting the reset switch on the modem and router, and ipconfig release/renew, but when I try ipconfig /renew it tells me "Unable to Contact Your DHCP Server".

the choice occurs at boot time and the hardware is enabled/disabled per

Hello,"Internet Explorer is using a proxy server on this computer to connect to the Internet." Hitman Pro gives me that message when I do a scan, and is unable to repair the problem. I did all steps suggested at this link, as that person's problem was very similar to mine: ("internet proxy?"). None of the procedures and suggestions contained at that link have worked. Also, Symantec's "Norton Power Eraser" reports two problems: m2wshlex.dll (shell extension) and deaddiskdoctor (directory).I have now done the steps at this link: ("Preparation Guide For Use Before Using Malware Removal Tools and Requesting Help").I've pasted the DDS.txt file immediately after this, and attached the Attach.txt and Ark.txt files.

Hi there, I'm having a bit of an issue with one of my computers. It's fairly new, running on Windows Vista.

I am able to connect to a wireless router (Belkin), but I am not able to connect to the internet on this one particular computer. Another desktop computer on the network is able to access the internet. I just get the error "Internet Explorer cannot display the page" on the laptop whenever I attempt to open IE.
I've read through quite a few similar problems on other sites, but have yielded no solution. Any suggestions?

I have a lab computer that I would like to use as a DHCP Server. However, I *ONLY* want it to hand out IP's via a specific interface (a second NIC I have).

Is this possible?

Answer:Windows Server 2003: DHCP Server on certain interface.

Well, it will only hand out DHCP addresses to those on it's network. If you have a totally different network on the other card- it won't be a problem.

What networks do you have on each card?

I have Comcast ISP and a Linksys WRT54GC wireless router. It has worked flawlessly until we lost power, now I cannot connect to the internet with it. The wireless network still exists and boadcast just local only. If I plug the modem directly into the laptop it works but it wil not work with the wireless router, I have also tried plugging into the router with an ethernet cable and still local only. I thought maybe the router was fried so I pulled out another router and I get the same thing.

Unfortunatly comcast will not help at all when it's a router issue. I was really hoping someone might figure this out I have tried looking up the DNS servers for comcast for my area and putting those into the wireless settings, I have power cycled the router and modem and have reset the modem as well.

Answer:Wireless Router, cannot connect to primary DNS server

I have a belkin wireless print server and i want to know whether there is any way to connect to the internet wirelessly using the print server......for example connecting adsl modem to the print server and then detecting it using my wireless laptop hence wireless internet connection?Anybody has any ideas?

Answer:belkin wireless print server connect net

Hi, I do not know if this is what you want to try but, the way i connected my D-Link print server was using my Belkin router. I wanted a wireless network as i have two laptops, i also wanted to print from the two printers that i had, from either computer without having to have both PC's switched on.I connected the D-link print server into one of the ethernet ports on the back of the router. I configured the router to accept the print server and Bobs your uncle. My D-Link print server was hard wired unlike yours. As far as i am aware you cannot connect to the internet using the print server. My Belkin router says something about the belkin print server and how easy it is to connect up.Sorry for the negative response but the good news is that the cost of wireless routers are very inexpensive, hope this helps.Regards Mike

Answer:missing dns server, missing rpc server no internet

What do you mean it connects to network but no internet?
Are you in a LAN? Since ip starts with 169
You should describe your network environment and it would be more helpful for people to diagnose.
For example if you are in a Corp LAN, maybe you need to set a proxy to connect to the internet etc.

When I do an IPCONFIG /ALL should the DNS address for adapter be the actual DNS address or the router address or does it vary depending on the router being used? Cause I see both in forum questions and was wondering.Thanks

Answer:ipconfig & dns server address

If the TCP/IP settings for the network adapter are configured to get the DNS Server Address automatically, the address will be allocated by the router using DHCP and it will be the router's own IP address. Sometimes, when there are problems with internet access, it can be beneficial to enter fixed DNS addresses using the ISP's actual DNS Addresses.

--I wasn't sure if home server was more based on XP or Vista, so i put it here--

hi all,
I have a router and a wireless internet connection, and i recently installed windows home server on an old desktop (something i've been meaning to do for quite some time). However, on the first bootup (when it had completely finished installation), It automatically loaded up an internet explorer page with a microsoft url. It said the page could not be displayed - great - No internet (sort of needed for a server).

I went to new network connection, and chose "always on", and it said it should already be working... chose repair. Well the thing is i don't know where the icon is that's usually in the system tray on XP and vista to connect to a wireless network.

How do i connect via to a wireless network?
Does it need to be plugged in directly via ethernet to my router?


Answer:How do i connect Windows Home Server to a wireless network?

home server was not designed to work wirelessly, this is explained within it's documentation. you do need to hard wire (cable) your home-server computer back to your network switch or router for it to log on and receive the internet. hope this helps

I feel bad for starting a new thread on the subject, but I looked through a bunch of the other threads and I couldn't find a solution.

I am on a Dell Laptop (Latitude D600)
And I'm running Windows XP Ver 5.1 Service Pack 3
My ISP is Speedlink Cable
We are using an SMC modem/router SMC8014WN

My roommate can connect to wirelessly, and I can connect with a hard wire connection. I also can connect to the router (full speed), but I get limited or no connectivity to the internet.

I connect to the wireless via a 'NETGEAR WG111v2 54Mbps Wireless USB 2.0 Adapter' using the NETGEAR SMART WIZARD - Wireless Assistant WG111v2

Answer:Can connect to wireless router BUT cannot connect to internet :(

Try putting static IP addresses in to your wireless network connection.
By the looks of it it seems your wireless connection cannot get an IP address automatically via DHCP.

Let me know if this works or you need help doing this.

Hi I need a little assistance. I am on a dell laptop running Windows XP Pro SP2. This is my mothers laptop and I have no clue what she did with it. OK, so I have an IP address, connected to Wireless network, can ping DNS Server, DHCP server, and Default Gateway. Tried the Winsock reset and the int ip reset. Also IPconfig release and renew. Haven't gone into the registry yet (Kinda nervous don't wanna mess anything else up. Need specific instructions). Uninstalled and reinstalled drivers (found online). Ran into a whole different set of problems and error messages, but I've gotten all those resolved already. I connected a LAN line with still no luck. I even installed Firefox. With all that done it still won't connect to the internet. I've used up all my tech savvy\expertise and I'm at a lost. Anything else you can think of that I can try? Thanks in advance

I'm messing around with W2K Server at home and can't seem to get it connected through my cable modem to my ISP's DHCP server. I know the cable and connection are good because it works on my W2K Pro workstation. I've tried ipconfig /renew but that's when the error occurs that it can't find DHCP. I can successfully ping the loopback address. The NIC is set to use DHCP.

Since I'm just becoming familiar with Server I'm sure there's something I'm not configuring properly. Suggestions?

Hi, folks. I've seen this question asked before, but I haven't seen an answer that works for this situation.

It was probably just a fluke, but I was installing an interesting WiFi monitoring program yesterday (, if you're interested - but DO NOT install this!). It prompted for a reboot, so I did. The PC wouldn't come back up, so I rebooted again; same thing. So I rebooted into Safe Mode, and discovered that I couldn't uninstall software in Safe Mode. I deleted the program directory, and rebooted again.

Now the fun started. Windows prompted me to reactivate XP Pro SP3, because of "significant hardware changes". But I couldn't, because I couldn't connect to the network - ANY network. I opened a cmd wiindow and tried "ipconfig /all", which returned "Windows IP Configuration" and _nothing else_.

I started getting errors about NCS2PROV.exe, which is apparently the network driver for my Intel 965DH motherboard, so I removed the LAN connection, reinstalled the drivers and re-enabled it. No luck. I figured that the onboard network connection had failed so I tried installing a USB WiFi device, with no success. I even tried doing a repair of Windows, without success. I tried looking for a restore point, but for some reason there are none prior to the crash and the oldest one didn't help.

At this point, Windows still is nagging to reactivate, I have no n... Read more

I'm posting this, as this is a very weird problem for me. I've installed xp on my laptop, after using the knoppix live cd in it. Knoppix runs fine, but once I installed xp, I can not connect to the internet or my home router. I have verified that the firewall is off, I can ping my loopback with no problems or errors. I have read a few posts, and have used some of the suggestions from them:
sfc /scannow
netsh winsock reset
netsh int ip reset reset.log

I have also disabled the NIC, enabled it, removed the driver and re-installed it, all with no luck. The system is using XP SP2. Also, I have formatted the drive and loaded xp for a second time, all with no luck. And I have made sure that TCP/IP box is checked and system is set for dhcp. Any thoughts? I could use some, thanks.

HelloI want to connect other PCs in my home to internet via cat5. The connection type is DSL. Someone tell me to make a PC as server and make other as client. This process is expensive and hard for me, because I have no experimental in networking.Is there any DSL modem that has switcher and can work like a server in home network?Thanks

Answer:connect to internet without server

If all you want is internet - Just buy a cheap Ethernet Router and use that.  If you want to sort of have a server you could buy a NAS Hard Drive which connects to your router and can be accessed on any networked computer allowing centralised storage and backups.

Hi. I'm not particularly tech-savvy, so forgive me if I missed giving you any important information.

My office has a wireless network that we use to connect to the server; it uses a Belkin router. We had to get a new lapop (a Dell Inspiron 14R) running Windows 7 Professional (upgraded from Windows 7 Home Premium, which was factory installed).

If the laptop is wired to the router, it can find the server, but cannot get to the internet. If the laptop is running on wireless, it can get to the internet, but not the server.

I've been through a bunch of forums, but most people had the opposite problem - they were unable to connect to the internet.

Our IT guy was here almost all day, and couldn't figure it out, but he hasn't had much experience with Windows 7. Any assistance would be appreciated.

Kate Hi and welcome
I am assuming that your office has older machine (vista, XP) because of the comment about the "new" machine.

Win 7 introduced a new networking feature (ugh) called IPv6. It is used in "homegroup" and sometimes it has connectivity issues on mixed networks.

Can you (or your IT guy) type cmd in search>right click and run as admin>
ipconfig /all and using the built in snipping tool (type snipping in search) make a screen shot and upload it to us.

Let us know if you need help with this
