I am doing some rewiring of the house and changing locations of different internet/networking devices. I had been just using a router, but with the expansion of my household wired network, the router ports are not enough.

What is the best way of routing my network....

Cable Modem -> Gigabit Switch-> Wireless Router
Cable Modem -> Wireless Router(has 4 extra gigabit ports) -> Gigabit Switch

Or does it really matter?

Answer:Cable Modem to Router or Switch first?

Second option. Modem - Router- switch.

I just picked up an Alix.2C3 embedded board for a monowall/pfSense router build. I also grabbed an enclosure from Netgate to house it - http://♥♥♥♥♥♥♥♥♥♥♥♥/6kcwmm

Now that I have it done, my network area is looking way too messy as I have a Motorola cable modem, the ALIX box, an 8-port switch, Vonage box, and a separate AP box. After looking at the ALIX, I am curious if anyone knows of a vendor who either sells or could fabricate a simialar enclosure that could house the ALIX board, the cable modem board, and possibly the switch board.

I have googled, but I am not sure what I am looking for specifically - anyone have an idea. Right now, I would even settle for a custom enclosure for the cable modem so that I could stack it easier.

Thanks in advance!

I need some assistance with our network at the office. We recently switched from having our data and voice being managed through a T1 and a phone server on site to having a cable modem and a virtual PBX.

Previous set up was T1 Line -> Box from T1 provided -> one line to the phone server and a second line to a SonicWall Firewall which then went to a couple of dell switches.

We have switched to a cable modem with 5 static IP's and a virtual PBX. Tech support for the PBX company suggested we configure our net work as follows.

--->Router---> Switch that connects to all phones
Cable Mode --> Unmanaged switch--|
--->SonicWall--> Switch that connects to computers

I configured the router for the phones and that works with no problems. But, when I configure the SonicWall with the information provided by our cable modem provider it worked but the SonicWall said it needed to restart after configuration so I clicked restart. Then the the internet connection wouldn't work and I couldn't get back into the SonicWall.

After numerous attempts at powering down the SonicWall and switch I finally was able to access it again and then the connection disappeared and finally I got access back again and reset everything to how it was on the T1 line.

The WAN setting on the SonicWall are as follows:

My question is if you switched off the NAT feature of a cable internet modem would it compromise the security of the router where the router could be hacked, irrespective if you have a good computer firewall or not?

Answer:If you switch off NAT for cable internet router does it compromise security of router

Technically pure NAT is not in any way a firewall. Typically NAT and firewall go hand in hand on consumer networking gear though.

If you are still using a firewall then no, turning off NAT won't put you at more of a risk.

Are you talking about a router behind a modem or a modem/router all-in-one?

Hi I have tried many resolutions and nothing. It all worked before with 2 cheap routers off of my cable modem (High Speed Cogeco Cable) but I couldn't password protect the routers because my wireless for laptop wouldn't log on at all?

1) So now I have a new rca cable modem (from provider) to a linksys ezx55w 5 port switch (not in the uplink port I assume since I have tried with and without from modem).

2) From switch to D-Link Di-524 (for wireless in yard and garage if I choose to bring laptop out here or around) to two computers in garage

3) From switch to 100+ foot of cat cable to house to an X-Micro also wireless for where laptop mainly stays) (cheap router but works great)

So all should be fine as I have researched and had replies to do it this way for ease of not conflicting hooking 2 routers together.


After reading I do not see if there is something in the settings I should do to each router still...since they (to me) are on seperate lines from the 5 port switch? Or maybe is this a cause from my provider not allowing me to use 2 seperate lines as I see it as well?

ANY HELP is greatly appreciated please been working on this for over 3 weeks now and read so much that all the scenerios don't make sense anymore.

basically i need to setup an additional wireless router to my isp's cable modem / wireless router combo, but they deny me access their modem page. maybe a long post, bare with me. heard this site was the place to go for this type of question. all help is appreciated!

i switched ISP's about a year ago, and when i tried to access my router page to port forward i couldn't get in. so i called and they explained they have their own password on their router so user's cannot change any settings. i tried to explain how this doesn't work for me an was basically told to bad. i said fine, can you just forward a port for me then, he said nope, "these routers don't have that capability" which is bullshit. i said ok i'll just reset it my self and use the default passwords, and i did, and withing a day or 2 tops the settings get switched back and im locked out again.

im in a 2 year contract so can't just back out, my ratio has been dropping on sites and need it for security system. i sent a msg to the staff and explained my situation, and we figured if i got my own wireless router, they cant do anything right?

so i just picked up a wireless router, its a d-link DIR-605-L, i thought i was just going to hook it up to the modem like the old days before isp's had the combo's, then realized it may not be as easy as it sounds. especially if i cant get into their router page.

Re: Connnect Wireless Router to Motorola SBG901 Cable Modem/Router Combo -ISP Deny Ac

i got the wireless router working, but im having alot of trouble port forwarding now. (some please answer, i got a paralyzed arm and takes me forever to type all this shit)

when setting up the router i noticed the box that i thought was for the phones only is actually the modem (arris tm602g) it says telephony on it, and had a spot for a phone line and tv cable wire, i pulled off a sticker and there was an ethernet port there. i tried setting it up direct but couldnt get it to connect. so the motorola sbg901 must just be the wireless router.

i hooked everything back up, then installed the new dlink dir-605L router like i normally would. after setting it up, it works great. i can connect to whatever wireless router i want. i have 4 or 5 pc's not including iphone and tablets, im no genius but everyone else in the house dont know how to copy and paste (literally) so i'd like to keep both routers, and use the new one just for me and my settings.

Hi everyone,

Before I begin stating my question let it be said that I am a dimwit in networking. I just learned from other people how to normally make it work and now the time's come that I actually have to do something and I can't really figure it out.

1. My home DSL is powered by an Aztech ADSL - DSL5001EN. Currently, the modem is set to PPPoE/PPPoA with a username and a password.

2. I have 2 PCs running on Wired LAN cards.

3. I do not want to purchase wireless adapters for either as I want to go wired on this.

4. I'd like to keep the Aztech as the DHCP server/router since it has a pretty good wireless range and all the features I need can be found on the GUI.

What exactly is the device I need and generally, what do I need to do to make it work the way I have it pictured?

Disclaimer: I may have mixed the terms a bit. I also know that I may not be making any sense due to the lack of knowledge I have in the subject. I wil not be held responsible for your brain and nose bleeds.

Answer:Should I purchase a Router/Switch/Modem/Router

The thing you linked is a modem-router, so it connects to the internet AND routes traffic between all the computers connected to it. Good.
Looking at the ports behind, it has only ONE Ethernet port. Bad, and where your issue is.

If you want to go 100% wired, you need an ethernet switch. It's a device that is smart enough to route the ethernet traffic from more than one PC through a single cable, but dumb enough that is plug and play.
Something like this is cheap and tiny (i've seen tons of exactly the ones I linked and their bigger 24-port collegues in all companies with decent internal networks). Plug the ethernet cables from your router and from the computers into any of its 5 ports, as it doesn't matter, and you are ready to go.

If you want to do something fancy like connecting ethernet (network cable) devices to your wireless modem router through wireless connection without buying wireless adapters, look for a Wireless Ethernet Bridge. These do need some setup to be integrated in your wireless network (as someone has to tell them the name of the wireless network they need to connect and the password), but it's usually straightforward as they are much simpler devices than the modem-router you have already.

Without the wifi connected, use IPCONFIG /ALL and look for the Gateway address - - that should be your[*]

Now connect any computer directly to a lan port on the new wifi router BUT leave the WAN port empty!
Again use the ipconfig and look at the Gateway address - - it MUST NOT BE - - that would create a conflict.

While connected like this, change the router address (say, limit the DHCP range to something like 2-16, set a new admin password and save the configuration. You will need to login again and now setup the WiFi SSID and passphrase for your encryption. Disable Remote Management and do not allow port 8080. Save the configuration once more.

Now you can add the WiFi router, but let's talk about the wiring.

No you can't because it doesn't have an RJ45 ethernet WAN port to connect to the Cable Modem - it can only be connected to an ADSL-enabled phone line.

I have a 2wire DSL/router that emits a terrible wifi signal. I have a Linksys WR110 that I want to use as my primary wifi on my home network. Problem is I can't figure it out how to make it work. Is it possible to run a cable wifi router off a dsl/router to use as an access point? or a stand alone WiFi point and just have the DSL/Router using the Lan ports only?

Answer:1 DSL modem/router and 1 cable router

If it was me, I'd do the following:

1. Turn off the wireless in the DSL router.
2. Turn off the DHCP server on the Linksys router.
3. Setup the wireless of the Linksys
4. Assign a static IP address to the linksys router in the range of the firs router. e.g. If your current IP for logging into the first router is then change the Linksys to or something.
5. Connect the DSL router from Port 1 to the Linksys router Port 1.

In effect, you use the DSL router to assign IP addresses on the network, and use the Linksys mearly as a wireless access point.

Need to no if I have this right

they have a dsl modem going to a Linksys router to a 24 port switch then to a little 4 port switch. sure, so then Would it be modem to router then router to any port on the big switch or is there an uplink port on the big switch it should go to? then you would hook a cat5e from one of the regular ports on the 24 port switch and run it to the uplink port on the 4 port switch need to no if the whole sequence is right. Hope someone can help, john will told me the cable would go from the big switch to the uplink on the small switch but I am wondering if I have it all right or not and wonderiing about from the router to the 24 port switch does the cable just go in a regular port in the big switch or if there is an uplink port does it go there. Hope you can understand my rambleing here. Thanks (please don't send me to a link) just need to no modem to router to regular port or uplink port on 24 port switch then from regular port on 24 port switch to uplink port on the 4 port switch.

Router to uplink port on 24 port switch, and then normal port on the 24 port switch to uplink port on the second 4 port switch. An auto-MDX port on a device negates the need to worry about uplink ports for that particular cable connection.

I currently added a steam link to my network. I ran a 25ft cat6 cable through my basement into my living room to give it a wired connection(wireless wasn't cutting it). I'm currently using a Netgear R6300v1 router. Well i had an old 10/100 router(Netgear wnr2000v2) lying around and wanted to also add wired connectivity to my xbox one for streaming to Win10 devices.(same room as steam link)
I plugged the long cable from router 1 into port 1 on router 2. Disabled DHCP and set a static IP address. But i noticed a slight latency when streaming games. Nothing extreme, but more latency on top of the normal latency wasn't desired.

To the question!
I would prefer to not have to buy another networking device, so would setting up QOS on the routers maybe alleviate some latency?
Someone I work with suggested i get another router, but for the price of gigabit routers, i opted to look into switches. I was able to find gigabit switches under $20. Would a switch be better than daisy chaining routers?

I thought that I had this all figured out, but my dad just asked me a question about my setup, and I can't answer it.

The setup is like this:
[ip-phones + computers]-->[small switch]-->[managed L2 switch]-->[router]-->[modem]

I have several ip-phones and computers grouped into blocks of 8. Each set of 8 is a medley of phones/computers connected to a small switch

Each of these switches, in turn, will be connected to a managed L2 switch that will create 2 VLANS: One VLAN will contain all of the phones, and the other will contain all of the computers. In turn, each VLAN will have its own router and DSL modem, thereby separating the network traffic.

I know that I can use this L2 switch to make the VLANS based on the MAC addresses of the devices. However, the smaller switches do not support 802.1q [VLANs]. Will it be a problem that the smaller switches do not support VLANs? Essentially, will this setup work to split up network traffic?

Thanks once again,

Answer:Computer, switch, switch, router, modem

I have the same DELL switch for my phones. You PoE will not carry across the linksys switches, so that is the first problem.
Next are the computers attached to the phones? Or does each device get its own drop?

And whats this about 2 routers and modems? Thats a bit over kill!! QoS would do the trick.

I would run all the devices off the Dell and attach the computers to the Phones (most IP Phones have a passthrough port) Configure the Dell with trunk ports with the Computer VLAN passing untagged traffic making it the native VLAN. While having the phones on a Tagged VLAN(If you phones conig allows you to set the VLAN in its config great! If not you can bind the MAC to the VLAN). The you create a QoS policy giving the VoIP traffic priority!

I have 4 computers.

A 2 year old Compac Armada laptop (Pre-loaded with Win2k), with an Intel Pro 100 Mini-PCI (listed under "network adapters" in device manager)

A desktop PC, (dual-processor) home-built out of spare parts (It's a nice one tho), w/ Win2kPro,with a D-Link DGE 500T network adapter.

Answer:Use ADSL wireless modem router with cable modem

There are just a few ADSL modem/routers that can accept an external ADSL modem via a USB port, but even fewer that can accept a Cable modem through an RJ45 port - the encapsulation has a big influence. To my knowledge, the Linksys models are not capable of it (although your model number is not clear - do you mean the WAG54GS or the WAG354G?)Prerequisites include the ability to switch any one RJ45 port to a modem port, the ability to disable/bypass the internal ADSL modem either manually or automatically and the ability to accept a PPPoE modem signal.

So I am updating my churches network and came to a setup I have never seen before. No one at my church knows anything about the setup except when they built the addition (about 5 years ago) they ran "a bunch of Cat5". They ran 3-8 jacks in every room. I have a closet full of about 50 cat5 cables of which only 16 actually have RJ45s on them and only 5 of which actually go to a computer. That stuff I was able to figure out. What perplexes me is the hardware setup.... I have seen modem to router to switch.

This install has a Comcast Modem with a built in 4 port router. 2 lines go to separate magic jack pro jacks. One is a straight cable to a wireless linksys router. The last is a straight cable to a 16 port switch. There is then a crossover cable from the wireless router to the switch as well. So on the switch port 15 goes direct to the modem and port 16 is a crossover to the router and back to the same modem..... I can figure out for the life of me why there is a loop going on here.

In either case the setup worked. So the duplicate line did not have an issue. I am so lost.

Answer:Modem to Router to Switch back to Modem, what....?

I would disconnect the cable going from the switch back to the modem/router combo. You're right. This loop is not proper. Loops should never exist on a switched network. I'm curious as to whether traffic is being forwarded around the network properly or if the switch being used has spanning tree support and might have shut down one of the ports wired up to the upstream network device.

Relevance 86.51%

Is this possible? Due to the layout of machines and incoming cables in my house I would like to connect the modem directly to a switch and then run a long cable to a wireless router centrally located inside my house. None of the other LAN ports would be used on the router, but the switch is going to have all 4 ports (Plus the 5th for the incoming modem) used.

As it is setup now, I can't see the internet from the wireless laptops. My laptop CAN see the other two networked computers but can only access one of them.

I'm currently connecting a port on the switch to port 1 on the router, not the 'internet' port. Either way didn't seem to make a difference.

I reset all the devices powering on the modem first, then the switch, then the router.

Ok, here's the run-down. I have Comcast Cable with a Motorola SB5101 modem. Earlier today I was trying to get an online game to work and I enabled DMZ for like 5 minutes. It didn't help my problem, so I disabled it and my settings were as they were originally. This is the only setting I ever changed, and I set it right back. However, whatever change it made doesn't seem to have been reversed. I don't really know what DMZ means or does (and I guess it's irrelevant), but I can no longer connect to the Internet.

My computers can all see each other via my router (Linksys WRT54G with DD-WRT firmware), but none of them can connect to the Internet. Connecting a computer directly to the cable modem works like a charm.

My question is, how do I get my router to get an IP address from the cable modem? I've power-cycled and rebooted my computer, cable modem, and router until my head exploded, and the router still says WAN IP: As I said, if I connect directly from PC > cable modem, I get a WAN IP and have full access to the Internet, but the router appears to not be getting an IP from the modem.

I have set the MAC address on the router to clone to the one on the modem, is that what I'm supposed to do? I get no connection through the router whether I clone my PC's MAC address or the cable modem's MAC address. Furthermore, if I am supposed to use the cable modem's MAC, should I use the one that says HFC MA... Read more

Answer:Router will not get IP from cable modem

Ok, this doesn't really make sense to me, but I told the router to clone the MAC address printed on the label on the bottom of the router. So it's cloning it's on MAC address, and that works?? I don't get why, as I thought the router needed to have the modem's MAC address so the ISP would think it was still seeing the modem. Ah, oh well, it's working now!

can any help me on how to connect my airtel mpls modem to a router

Answer:modem to router cable

I would expect it to be either an RJ11 modem lead (small square plugs) or an RJ45 Ethernet (larger, more rectangular plugs). That's assuming that you have the right bits of kit to work together. Do a Google image search for those RJ numbers and see if they look right, then head over to Ebuyer or the local PCWorld or wherever you prefer. There are different flavours of RJ45, but any standard Cat5 patch cable should be fine.

Question: Cable Modem/Router I will start off by stating that I hate my apartment and how the cable is wired in the place. I have one line going into the apartment. It is in the living room. In order to get too any other point in the house I have too run cable lines around rooms and hook up too connections in wall that pass through the wall into the next room. I currently have my computer located in the dining room/kitchen area as I have a huge area and a small table. Too get too my computer with cable line it takes 3 connections to hook up too my modem (modem is last hook up). I would like to move computer too too bedroom, but too do so would take 6 different connections. Would I be losing "connectivity/bandwidth" by having 6 different connections or would it be better to get and hook a router up in living room and run a network line too the computer and cutting out those connections??? I would like to get the most out of my internet connection if you feel me.

Basic question? Will I get better connection using router over 6 connections??? Not sure about data/packet lose in the connections.

Do you mean cable in that it's not wireless, or cable in that it is designed to connect to a cable modem? If the latter, you have the wrong kit. Cable broadband doesn't use VPI/VCI. If you actually have an ADSL modem/router, VPI/VCI is 0,38, multiplexing here

Okay, so this is basically my setup.

I'm using roadrunner's sb5101 cable modem...connecting this modem to a netgear hub with 4 ports.....

1 port receives the connection from the cable modem
1 port connects to my computer
1 port connects to my 360
1 port connects to my dlink router

here's my problem: all the connections work fine except for the dlink router; it doesn't seem to connect to the internet.

When I check the status tab, it says "dhcp client disconnected". I try the release IP and it says it was successful, but nothing happens. I try the renew ip and it says renew ip fail (obviously since it doens't have an ip).

So my question is, is it a crappy router? Am I missing something here?

I tried resetting the router to factory defaults by pressing the hard reset button in the back, and it sitll didn't connect.

Someone please help.

Oh, the reason i'm not connecting the modem to the router is beacuse the stupid router doesn't give me a static ip, so i'm banned from several sites and I need a static ip.

The modem needs to plug into the WAN port on the router first.

If the router has 4 ports just plug the 2 machines into the LAN ports on the router.

You can also add a switch with more LAN ports which you would plug into the routers LAN port using Ethernet cable.

Hi everyone,

Hi, I'm a sorta newbie/intermediate. I don't have professional networking experience. I'm even a little unsure of subnet masks.

I hope my newbie questions won't be too irritating.

A local charity wants to keep costs low by separating out their office computers from the student computers and also a satellite charity in the same building. That makes effectively three separate networks. Right now they have one simple 16 port switch on which all the machines are connected. Both the office computers and the dependent (rather smaller) charity have sensitive info on the computers and the charity boss is adamant that he want the networks unable to see each other so that at least his office computers are in a walled garden, so to speak. There's no real server just a shared folder on one of the desktops (only 3 computers in the main office).

Rather than a real physical separation, which would expensively entail 3 separate internet connections, I was thinking to do this with vlans. Am I on the right track?

Presumably I would configure 3 vlans with different subnets. How might this work with the (rather old) consumer netgear broadband adsl router?

For example, presumably the netgear would have its DHCP server switched off. Then presumably the managed switch would hand out the correct ip addresses for each vlan with its own dhcp server. Is that right? I am supposing that each vlan would have a different subnet, but maybe this isn't necess... Read more

The dsl is sbc yahoo dsl. The network is used for file sharing and gaming. I have been fairly happy with the smc router although the netgear one is evil incarnate.

The network is being expand to expand from five ethernet cables to twelve. Instead of another switch or hub I would like to simply replace the old router because, well its old. The modem is held together with a rubberband and melts that ever few months; its also up for replacement. I'm looking for suggestions, and they don't nessarily have to follow the kind of setup I've outlined as long as it supports the nessary number of ethernet jacks (twelve plus one for the modem).

First, the setup here is an ancient RCA DCM105 router (works just fine but seems to be limited internally to around 3mbps downstream). From there, a Netgear WGR614 v4 54 Mbps Wireless Router distributes the internet connection.

My current plan is 8mbps downstream, 784kbps upstream. Because of the hardware limitation, I ordered a new DLink DCM202. When I got it, I hooked it up, and before I called Comcast, it connected and worked. However, it connected at 6mbps, 384kbps. I posted about this separately, and it's not too important, but long story short, the MAC is not unique and the modem connects via someone else's account. To test this... I called up Comcast and cancelled my internet service.

Anyway, because I actually care more about upstream most of the time, and because I need to have both modems working for about a week (after I move and before my roommates do), I hooked the old modem back up and got my service reconnected. This is when mucho problems started. Those of you familiar with Comcast probably have seen the screen you may get when you first connect (via ethernet) and open a browser. It says you must download software and register your modem before proceeding. Keep in mind that I already registered over the phone.

OK, this is my third post today...someone must have something to say about this (I hope)...

I had cable modem service at my old apartment for over 2 years without incident. We moved into a house a month ago and I have gone through 2 cable modems and 2 motherboards (with built-in NICs) in that time! The last time also fried one port on my brand new router (but the other ports are fine).

I am desperate for a surge protector to connect to the coaxial on my cable modem, but apparently there is no such animal. The store where I bought the motherboard just ran the diagnostics and told me that yes, the port is out and the NIC is bad. They will replace them both, but I am really afraid it's going to happen again. Especially if it is lightning or something that is causing this.

The tech suggested that the computer that was grounded better was the one with the problems, but he wasn't sure. My question is this:
- why is none of this happening to the other machines on the same router
- how can I insulate the troubled machine/NIC/motherboard/router from being affected by power surges in the future, and
- is there a cable modem surge protector type thing that I can buy/build whatever.

I have 2 pcs hardwired to a Linksys router that is connected to a cable modem. Both pcs get to the Ineternet fine. All I want to do is transfer files between the two computers and still be able to connect to the Internet via the cable modem from both pcs. I have a crossover cable, but not sure why I would need it if I'm connected to the router. I have zero knowledge of setting up networks.

Answer:Cable modem to Lynksys Router to 2 pcs - how?

If both computers are successfully connecting to the Internet through the router, you do not need the crossover cable.

Make sure you can ping the other computer's IP address. If this fails, just for testing, make sure you turn off XP's as well as any other firewall.

Make sure you can ping the other computers by name.

Make sure you have the same workgroup name (watch for trailing spaces)

For troubleshooting purposes, turn off XP's and completely uninstall any other firewall software. You can always add more complexity after you get it working.

With XP, make sure you have the same username and password as the person logging onto the other computers. The default setting for XP Pro is to require a password for network access.

More details about how to network XP can be found at:

There continues to be a lot of misinformation about needing NetBEUI or to changing the NetBIOS setting. You can ignore both. Installing NetBEUI to solve a networking problem will just mask a some underlying and potentially important misconfiguration with TCP/IP. The default NetBIOS setting works fine so there is no need to change that either. Just don't disable it.

Hey guys, this is my first post here. Hello to all!

I'm using a cable internet service which requires me to login every time using their login page which opens in a browser when i try to access a website. This has to be done everytime the modem restarts (which is frequent due to frequent power outages in my country )

I have to use a wireless router since my primary machine is a laptop and I can't sit at one place with the ethernet cable connected to the modem all the time. With the wireless router, the system is unreliable. Sometimes it will open the login page, sometimes it wont. Sometimes it will open webpages, sometimes it wont, and sometimes it will only open select pages.

I was wondering if i can use some setting on the router to save my username and password for the cable internet service that would automatically log it in so i don't have to do that manually every time. It could be done with DSL using the PPPOE setting, doesn't that work with cable internet?

I'm using the Linksys WRT54G.

Answer:Cable Modem and Wireless Router

You didn't mention which country, but I will make some assumptions.

No, PPPoE doesn't work on cable modems, so you can't use that. On most routers/cable modems, the web page thing is an configurable option on the router. You need to turn it off. Contact your ISP about turning it off.

In the U.S. cable service does not require a log in (by the user) The cable modem does this automatically before the modem even comes up. It is invisible to the user. ADSL always requires a login. This is where the PPPoE auto login comes in.

Hello, I am in the market for a cable modem / wireless router combo. I have looked at reviews and can only seem to find a d-link. I have had problems with them in the past and I am now trying to avoid that brand.

Does anyone here have experiece with any good cable modem / wireless router combo's?

If you didn't have a good experience with one, which ones should I avoid?

Any advice would be greatly appreciated.

I am connecting via Time Warner-Roadrunner with a Netgear CGD24G cable modem gateway.
I am always having trouble with DNS.
DNS is not able to resolve IP addresses.
DNS Server isn't responding.
Pages are not usually opening and most of the time when I click refresh, nothing is happening. Refresh button appears in 10% of a second.

I don't know how to resolve the problem. I can try connecting via USB, but I haven't found the driver for it yet. Thanks to NetGear, there is no driver on internet or in the resource CD.

The other solution I am thinking is using the D-Link DIR-615 router. I am thinking to add it to the CGD24G gateway (because DIR-615 doesn't have a coaxial cable input). They obth have as default address. How should I change the modem and router gateway addresses? Should I change the CGD24G to (which I already did actually)? When I do that, do I need to change the IP addresses

from -
to another range or leave it the same?

Do I need to change the IP addresses or the subnet mask on DIR-615 if I add it?

Is there any solution for DNS and Key Ports problem with CGD24G on a Windows 7 Ultimate x64 OS?

Does anyone have a USB Driver for CGD24G?

I hope I could make myself clear. English is not my mother tongue, and my expression of my thoughts can confuse native speakers time to time.


Answer:Cable Modem Gateway + Router

One of the problems you have is that router will severely limit your internet speed. I had one with the comcast connection and it dropped me from 21MBs to 6 MBs. Once I trashed that and went with comcast's modem I was back up to full speed. Seeing how you pay roadrunner, I had them when I was in TX., I would call them and tell them that you want to switch to AT&T. Not that you really are intending to but let them know this. Then tell them the problems you are having and that is the only reason you are thinking of canceling with them and switching to AT&T. Watch how fast they quickly offer to resolve your problem by sending a Tech out for free and fixing the problem for you. They key word here is you have to tell them that you are thinking of canceling with them and switching to AT&T. That should fix your problem with no headaches on your part! Post back to what they reply with you.

I got the Tv cable coming into the modem and by ethernet cable going to my linksys wireless broadband router. Which supplies a signal to my other two computer located upstairs. Also I got from the wireless router a ethernet cable to my computer. In the past I had this working. Working fine but lately it has a problem. I Found out that when I turn on my main computer down stairs the one connected hard wire that I lose the signal to the computers up stairs which are wireless. If I turn off my computer down stairs then the wireless system works. My system is Microsoft Windows Xp, HP Media center Edition Version 2002. I restored my computer hard drive back to the factory settings and I still am having the same problem. So if anyones has an answer I would be interested

No, you cannot use a modem/router as only a router.

You can use it as an ethernet switch and wireless access point, but you are going to need a router.

So I have had some ongoing worm on my personal laptop that tries to reroute IE or firefox to various crap websites if you incorrectly type in a web address. I did a TON of clean up with various spyware removal software, and I think I have killed 99% of the problem. Eventually I will backup all my important info and reformat my laptop. Now here is where it gets interesting...

I connected my work laptop to my home wireless network, to get some work done. I never ever would go to an inappropriate website with a work laptop. Somehow my work laptop was infected with the same virus. I didnt realize it was infected until at work my laptop was trying to go to the other sites instead of the company intranet page.

I have cable isp. Modem(Motorola surfboard SB100) is usb connected. Ethernet connection from modem to Linksys wireless-b router(befw11s4). Wireless signal to sons xbox live. Router is not connected to computer. This has worked fine since installing the router nearly 3 monthes ago. Computer is generally on and no problems with him gaming while I am on puter.

Problem began 2 days ago after I contacted isp to change service package. My current level of service(768k down/128k up) would no longer be offered and I would either have to take their new 2meg down/256k up for a slight increase in price or downgrade to their 384k service( not sure of up speed) for the same price as I had been paying. I opted for the 2meg.

Even though I had been receiving the 2 meg on trial basis I was instructed to unplug modem to reset it. I have also done this before with no problem re-establishing connection.

Here is problem: maybe the upgrade and resetting the modem is just coincidence but that is when the trouble began. Both devices(computer and xbox) can not share connection. It seems whichever device has the isp configuration numbers first is boss and the only way to allow the other device access is to unplug and reset modem amd allow it to access with the other device off.

Many thanks in anticipation of help.

Answer:Cable modem + wireless router

Generally,the cabling is.
Cable connection to modem
ethernet connection from modem to router's wan/internet(could be called either)
If you want a wired connection,then from the router's lan port,ethernet connection to your pc's lan/ethernet port.

Before doing anything,power off both devices.
When completed with cabling,power on modem first,wait for it to settle(proper lights on)
Then power on the router and as above,wait for it to settle(generally,power light,wan light,internet light and ethernet port light if you have a hard wired connection.)

Then,log onto your router's admin page and set up your wireless network(security encryption,wireless mode,name,channel,etc.Hopefully you have a user's guide for your router)
Hope this helps a bit

OK, I'm running a Linksys cable modem with a Belkin router. The router is a 2.4g 802.11g wireless.

The problem is just that we have 5-6 laptops running at once, two are Macs, and they're all competing for some bandwidth. The cable and router go down frequently and have to be unplugged and restarted again and again.

This especially happens when someone is watching a recorded show on our media center PC (HP), through which the router and modem operate.

Can I even explain how annoying it is to have to constantly get up and unplug and then replug in the router and modem -- or yell through the house for whomever is sitting at the computer to do it -- and then have to wait while the connection is re-established? And this is nothing to say of the content that's lost when it happens.

Anybody have any ideas about this? Do I need a new modem AND router? Do they make them so they can handle more computers?

According to the user's manual on my cable modem (a motorola SBV5220), "You can connect a single computer to the USB port and from one to 31 remaining users to an Ethernet hub, as shown."

Comp \
Comp---Ethernet Hub or Switch----Cable Modem

Does this mean that I could use an ethernet hub or switch to share my connection over 3 or 4 computers, or would i need mutiple IP addresses to be able to do this (in which case i would use a router instead)?

Just seeing if i can save a couple bucks. If anyone understands what i'm trying to say, thankyou for your assistance.

Answer:Will my cable modem serve as a router?

That tech support person at Motorola certainly is not on the "A" team.

I found the "data sheet" online. No mention of the magic words "router" or "gateway" so I think that it is safe to say the suggested network (which is also in my Motorola SB4200 manual) implies multiple IP addresses.

As you suspected, you want to put a router in that diagram in place of "Ethernet Hub or Switch."

Would it make any sense (networking n00b please forgive)...instead of letting everything to run automatically, to do the following:

Cable Modem to Vonage Box to Router...set the Router from Gateway mode to Router mode (since the vonage box is essentially the first router and the Linksys is no longer a gateway) and then use the following advanced settings on the router:

Does this matter???Can anyone help??Thanks.T

Answer:Can I replace my Cable modem with router??

The Netgear WGR614's WAN port should be connected to the Cable Modem's ethernet port. The Modem's USB port is *NOT* used. The PC, and any other devices going online, connect to the Router, either via one of its four LAN ports or "wirelessly". Therefore Q1 - you cannot dispense with the Cable Modem, the Router connects to it.Q2 - When using a router, you must connect by ethernet, not USB. Unless the PC doesn't have a network adapter installed, there is no good reason for using USB in any case, ethernet should always be used in preference to USB. Also, ensure you follow the correct procedure when swapping connections to the Cable Modem:Power everything off, including the Cable Modem which must be left without power for three or four minutes - this is IMPORTANT so that it loses the association between the existing connection (recognised by its MAC address) and the IP address that it has allocated to it.Connect a network cable between the router's WAN port and the Cable Modem's Ethernet port. Connect a second network cable between the PC's network port and one of the Router's LAN ports. Power on the Cable Modem and, when fully booted with all lights displayed, power on the Router. When the router is fully up and running, boot the PC. The Cable Modem will recognise a new connection and allocate a different IP address to it.If you now type the Router's IP address into your web browser you should be able to open its configuration pages to set it up for wireless networking.

Update the firmware on the router. Sometimes the ISP makes a change that requires that you have the most recent firmware for your router.

Sounds like you can get to the net by connecting the modem directly to the PC. You'll need to do that to download the firmware.

Answer:Cable to Modem 2 router 2 wireless help PLS

Start by telling us the exact make/model of the modem and the two routers.
Here's a suggested configuration that should work, but it's based on the limited information we have to work with.

Here's what I'd do first, this is using the modem and the wired router.
Reset the router to factory defaults by holding the reset button down for 15 seconds with power on. The following procedure should get you a connection with any broadband modem that is configured to use DHCP for the router connection, such as cable modems, and many DSL modems. If you require PPPoE configuration for the DSL modem, that will have to be configured to match the ISP requirements.
Turn off everything, the modem, router, computer.
Connect the modem to the router's WAN/Internet port.
Connect the computer to one of the router's LAN/Network ports.
Turn on the modem, wait for a steady connect light.
Turn on the router, wait for two minutes.
Boot the computer.

When the computer is completely booted, let's see this.

Hold the Windows key and press R, then type CMD (COMMAND for W98/WME) to open a command prompt:

Me again, I'm trying to disagnose my father's internet issues for him and cannot figure it out. Neither him or anyone on his network can stay connected to the internet. After looking at his router security log I see why.. Heres a copy of the log..

System log:

Answer:Cable Modem/Router problems

I have a netgear mr814 (v1) wifi router ( and a motorola sb5120 cable modem setup in the house.

My question is that when connected directly to cable modem my download is 25Mbps and upload is 770Kbps. When connected through router (all wired btw) it drops to 6Mbps and upload is 300Kbps. In the specs for the router it list the network speeds at 1,2,5.5,11Mbps. Is it defaulting to the 5.5 in this case or something? Replacing the router definitely seems like it would work. What do you all think?

Is there a combined router/cable modem you all would recommend? I am renting the modem from comcast (for a bit until I decide and then just order it online for around 40$) otherwise and one of these from the list below.

Any picks out of these ones? Was leaning towards the linksys.

LINKSYS WRT54GL IEEE 802.3/3u, IEEE 802.11b/g Wireless-G Broadband Router

BUFFALO WHR-G54S IEEE 802.3/3u, IEEE 802.11b/g 125M Wireless Cable/DSL Smart Router

BUFFALO WHR-HP-G54 IEEE 802.3/3u, IEEE 802.11b/g Wireless-G MIMO Broadband Router and Access Point
