Question about backbone networks

Question: Question about backbone networks

Hey guys,

I have question about backbone networks. Need Help!

If an organisation has 3 departments.

Key servers are in different departments ? so a user from 1 department X reads and writes to file servers in another department Y. And both users access mail from a server in department Z.

The traffic and broadcast storms originating in one department is causing bandwidth saturation in other departments.

The core of the network is slow and is unable to meet the response time requirements of various critical business applications.

What is the solution based on core technology design, LAN technologies and design solutions to address inter-departmental traffic issues?

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.)

major faux paux. Broadcasts should not go beyond the current subnet.

I would guess

you're departments are co-located in the same building
and all are on one subnet
For large companies per the above, likely the 192.168.x.y is insufficient and your lan is using a subnet like 10.x.y.z for ease of network administration.

Broadcasts should be limited to resource online/offline and contained within the network segment where the device is attached. Users / systems in HQ do not need the status of a printer going offline the the shipping department.


segment the departments into unique subnets
then add static routes between them according to their need
eg: the company domain server would be needed by all (dept <-> srvr)
including the email and directory system.

FEW departments need access to the sales group or its data

You need to analyze the departmental workflow to begin this project, and implement one network change at a time.

This is not a real life situation, it's a small part of a report I have to do for college.

Basically I have to plan a full network for an 8 storey college building. I will place serveral networking closets (IDFs) to provide full coverage. Because of the size of the building, i'm guessing a fibre backbone will have to be put in place, this is where i get confused about the equipment I need.

Core level - Redundant Routers with GBIC interfaces
Distribution level - Fibre Switches?
Access level- Ethernet Switches with GBIC interfaces

I need to have a good redundant setup in place. I've looked into the fibre switches and I have calculated I will have at least 20 fibre runs to the closets (also need room for expansion).

I can only seem to find some kind of HP fibre switch that has 16 empty GBIC slots, which runs for 5,000 plus all the GBIC cards.

Can someone give me a hand to tell me if i'm going the right way and what equipment i should be checking out?

Answer:Fibre Backbone Help..

when dealing with fiber, there are a few things to consider:

single-mode vs multi-mode (need based on distance requirements)
SC GBIC vs LC SFP (connector types)

those are the main things, but if you are planning for expansion, i'd look into a fiber patch panel and fiber trunk cable. that way you can run the fiber once and patch in when you need new connections. I wouldn't run fiber for anything except the 'backbone' of your network (between stories/floors).

Question: Network Backbone

I have a question in regards to a network backbone. From what I understand, the network backbone generally is capable of a higher throughput than other connections throughout the network. For example lets say that I have a network consisting of one hub, three nodes, and two servers. The three nodes are connected to the hub via CAT 3 UTP @ 10mbps, hub is connected to switch via CAT 3 UTP @ 10mbps, and from the switch the two servers establish a connection via CAT3 3 UTP @ 10mbps. Now if I wanted to enable quicker access to the servers, could I just replace the NIC cards in the two servers with a 100BaseTX NIC and replace the existing CAT3 cabling with CAT5? Is this essentially what a network backbone is? Please help me understand exactly what a network backbone is and how it should be properly implemented.

Ever wonder what the wiring of the Internet looks like? The major node-to-node connections
are the backbone of the Internet. From any backbone node, major players connect one to another
(eg Universities and ISPs) and we (the home users) get service from there.

Here;s a site that maps the Internet with the ability to select by geography
(US, Europe, Asia, ALL) and then by network owner (AT&T, Quest, Ten, ESnet) and many more.

Point of interest is the link from the US to Europe is only the latter two.

From my perspective (ie: Los Angeles, CA), the path to TS (in Dallas, TX) is
AT&T World Net

Hello everyone,

I'm about to embark on the process of upgrading our backbone switches from 1Gbit to 10Gbit, and was wondering if I should go all-fiber for the backbone (All SPF+), or go with 10Gbase-T with SPF+ uplinks?

Basically, I'm debating between getting the Netgear XSM7224 or the Netgear XSM7224S. Any thoughts or possible pitfalls I should be concerned with?

Thanks for taking the time to read this,

- Space

Answer:Upgrading Backbone of our network - Looking for advise

SFP+ is generally uses less power and the add-in NIC's are cheaper. Honestly, the downfall is the lack of interchangeability/cross-compatibility on DAC's. Generally crossing brands of optics works but if DAC's is your goal it can get dicey. Long range capability & low latency is also nice. Fiber is cheap and generally easy to work with especially if you aren't new to it. If your upgrade involves running wire, i recommend using the best fiber you can afford/justify, taking the distance into consideration. Future-proofing for 40Gb & 100Gb could be attractive, just be sure to run a minimum of 5-pair (10 strand) fiber on long distance runs.

10Gbase-T is just about standard for new servers with 10Gb capability built in. You are seeing less and less SFP+ based NIC's built in. Standard CAT6 patch cords can be nice in a data-center is nice if that's what you are set up for (if you have fiber trays as well it's not really an upside). Downfall is shorter distances, higher latency and higher cost for add-in NIC's. The latency could be enough to warrant using optical based media in storage network environments. We aren't talking huge difference but in the storage world it makes a difference.

In my memory using Norton ConnectSafe from Netherlands always showed a server in Ireland, Browserleaks showed a DNS in London (Level 3 communications). So I clicked on the DNS IP and to my surprise it was part of the Neustar infrastructure.

So either I was unaware of something good in the past (Norton DNS using Neustar backbone) or it is really a change. Anyone know whether Norton ConnectSafe was using Neustar (with paid Express DNS and free DNS Advantage service) in the past?

TCP Protocol Controls Routers

POSTED: 4:47 p.m. EDT April 20, 2004

A flaw that could potentially disable large parts of the Internet has sent security experts and governments scambling for a cure, technology Web sites and other sources reported Tuesday.

The problem is with the Transmission Control Protocol, which lets servers that send out information and routers, which decide how it is transmitted, to work together.

Britain's National Infrastructure Security Coordination Center said it could be a critical problem. The advisory says that flaw could be exploited if long TCP connections are shut down unexpectedly.

These are known as "reset attacks," according to A security researcher named Paul Watson discovered the problem.

An expert described the problem as affecting the glue that holds the Internet together. reported that there has been a secretive effort over the last few months to fix the problem.

Previously, it was thought that there was only about a 1 in 4 billion chance of someone guessing the information needed to cause a reset; Watson showed that it can be guessed within four attempts.

Tuesday's announcement came just two days before Watson is scheduled to present details of his work at an Internet security conference in Vancouver.

Watson predicted hackers would understand how to launch attacks "within five minutes of walking out of that meetin... Read more

Answer:Protocol Of Internet Backbone Vulnerable To Hacks

How Internet Infrastructure Works
Content provided by

One of the greatest things about the Internet is that nobody really owns it. It is a global collection of networks, both big and small. These networks connect together in many different ways to form the single entity that we know as the Internet. In fact, the very name comes from this idea of interconnected networks.

Since its beginning in 1969, the Internet has grown from four host computer systems to tens of millions. However, just because nobody owns the Internet, it doesn't mean it is not monitored and maintained in different ways. The Internet Society, a non-profit group established in 1992, oversees the formation of the policies and protocols that define how we use and interact with the Internet.

In this article, you will learn about the basic underlying structure of the Internet. You will learn about domain name servers, network access points and backbones. But first you will learn about how your computer connects to others.

A Hierarchy of Networks

Every computer that is connected to the Internet is part of a network, even the one in your home. For example, you may use a modem and dial a local number to connect to an internet service provider. Or you may use a cable modem or DSL connection. At work, you may be part of a local area network, but you most likely still connect to the Internet using an ISP that your company has contracted with.

Hi everyone,

I am new here. I work at home for a large company via their secure website. For the past few weeks, there have been many times that I cannot get on the company's website (based in Internet Explorer). The website doesn't connect at all. During these times, I can access all other websites without any problems, so it is not a problem with my internet connectivity. The company keeps telling us that the problem is "an internet backbone routing issue" and there is nothing that they can do about it. My question is if this is really legit? Can there really be an issue that only affects my ability to access that one specific website while still being able to access all other websites without problems? I've checked my download and upload speeds through my ISP (I have a Road Runner cable connection) and they both looked good during these times. They claim that they can do nothing about this problem, but it has occured every day this week. Could it be some sort of problem on their end with their servers being overloaded or something? We are paid on production and don't get paid for downtime when their website is down. Is there anything I can do about this to prevent it from happening on my end? Thanks so much for the help!

This is a bit out of my expertise range, so this could be a completely "not possible/insane" request. However, as there are many degrees of connectivity to the internet, this has me wondering...

Right now, I am connecting to a datacenter in Chicago from North Georgia. This normally requires a route that goes from my ISP to Cogent TN, then Cogent IN, and then eventually goes to AT&T where the datacenter is connected to. There are also other stops that pile on latency as well.

However, I am curious as to if there is some form of packet "tagging" to manually force the packet to go to another network immediately off the bat. This new route, for instance, might instead go HE's ATL network, then right to HE's Chicago, followed by AT&T Chicago (possibly reducing latency.) Another option could be all AT&T from ATLN -> STLS -> CHCG.

The first hop is going to depend on my ISP's peering, but it would be great if I could manually plan the route out statically after them to the end destination.

Can this even be done? If so, would this require some sort of expensive "multiple agreements" thing with different Tier 1s, or is there some secret "route tweaking" packet option?

This almost sounds like some sort of odd internet voodoo or wizardry.

Answer:Custom Routing over Specific Backbone Routers

Theoretically there's an IP option for 'source routing', but I think that's generally disabled on the Internet, because it causes more harm than good.

You could try experimenting with IPv6 -- routing may be different / more advantageous; or you could try using an HE tunnel on either or both ends, if you find better routing through HE than your normal routing.

I was trying to log onto a network at my house with an SSID of "Free Public Wifi". Since I bum my internet off unsecure networks, I figured that since this one was stronger than the current one I was using, I would give it a try. But, when the connection went through, my laptop gave me the infamous blue screen and froze. I had to reboot my system. When I looked at the network again on my computer, it turned out to be ad-hoc.

I'm wanting to upgrade my network to Gigabit.

Something that's always remained a mystery to me is if let's say my router has 10/100 ports that I attach to a gigabit switch. I have two computers with gigabit cards connected to the switch and I want to transfer a file between them (on the same subnet of course).

Here's where I get confused, and admittedly I don't have much more than basic TCP/IP knowledge. If I initiate a file transfer between the two machines, do the packets flow through the router for the entire transfer or just on the switch matrix itself? Would the router which is only running at 100mb be a bottleneck, or do the packets just flow on the switch giving me true gigabit speeds?

Answer:Question about routing/networks

The PC's will talk directly to one another. The switch will have both PC's mac addresses in its mac table.

Hey guys, I'd appreciate some input from you networking gurus on something.

Right now, I've got kind of a hybrid network at home. Our only cable line comes in through the garage and so we have the following setup:


cablemodem (comcast 16mbit) -> D-Link DR-655 router -> powerline (homeplug AV 200mbit)

upstairs --> powerline adapter -> Netgear N router
upstairs2 --> 4port powerline adapter -> ps3 / pc1 / pc2

The upstairs router and the downstairs router are 2 diff wifi networks, though the upstairs router is just getting the signal from downstairs. All this is because our house seems to be wifi proof and it's difficult to have one wireless router serve the whole house.

Both my dad and I work at Cisco and are planning on getting a Cisco vpn router so we don't have to login to vpn all the time. I believe it's a Cisco 871 CVO - so I'm trying to see if I can have a similar setup using powerline adapters and a 2nd upstairs router.

There is another powerline standard that isn't compatible with Homeplug AV (simply Homeplug I think?) So I was wondering if I could have a separate powerline lan using those adapters. Would the two powerline lans conflict with each other even though the devices would ignore each other?

Or should I simply use a d-link repeater I have laying around and use that to repeat the cisco router signal?

Hi, I'm new to the forums here and wanted to ask a question about home networks. I have an Acer desktop PC that has a slow network card (100 mbps) built in, which I had been using until yesterday. The home network I used with Windows 7 was named "Scott's PC Network" I disabled the network card and installed an Edimax Nano wireless adapter, which is connecting at 150 mbps. I now notice that my home network is renamed "Scott's PC Network 2" and there is a "Wireless Network Connection 2" on the computer also. Can anyone tell me if this is normal or if it can just be renamed to the original "Scott's PC Network"? The only thing I can think of is that since I disabled the onboard network card, that Windows renamed the wireless connection. Also, when I look at the available wireless connections at the bottom right corner, where the 5 white bars are, it shows "Scott's PC Network" with the "Wireless Network Connection 2" above it.

When sending data across a wireless network (from your PC to your Wireless Router to the destination PC across the globe), from your PC to your wireless network, is this considered a OSI Layer 2 or are we in the Physical layer already.

I'm now self-studying for an CCNA, but the OSI concept still boggles my mind to some extend.

I am trying to re-configure my home network to allow for a secure and normal (not to secure) networks, that will not be aware of each other but will both connect through to the same router for Internet access.

Basically I want one network that will be used only for Online banking, other important transactions and store important data and another which will be used for random web browsing,web mail, games etc that are more likely to get Spyware or Viruses.

The two networks will only have a few computers/laptops on each network and obviously as this is for home I want to know if this is feasible without spending huge amounts of money. If anyone sees any problems with my thinking or has any advice please let me know.

Am I correct in thinking that all I need is 3 routers?
1. Wireless ADSL Router connected to phone line that receives Internet.
2. The secure network router that connects to 1 and several computers.
3. The standard network router that connects to 1 and several computers.

2 and 3 would each have a separate wireless SSID and workgroup and use DHCP within different ranges to allocate IP's to the various computers.

Is there anything specific that I would need to do to the routers configuration to get them to work?
would the ADSL router need DHCP as well?
Will I need to configure different subnet masks?

Any help regarding this is much appreciated.



Answer:Home network configuration question (2 sub networks)

That will work. The secondary routers need to have a different subnet from the primary router. It doesn't matter if the two secondary routers use the same subnet.

Not sure how you are using the word "secure." I would advise WPA-PSK (or WPA2) on both wireless networks.

Simple Question...

This is just a simple problem that I just cant figure out. I attached a picture so I could explain better. The purpose is that I want to be able to share all my printers and also I want to be able to transfer files between the computers, so far I have been able to look from the 10.0.100.X network to the 10.0.10.X network but I cant seem to get it to work the other way.

I am no master of networking but! This is kind of my special project, my family is going to be really glad, the thing that looks like a lightning thing means that its trough wireless, the reazon I dont use only ONE router is that the G router is mine and I do a lot of heavy transfers between my laptop and my desktop and when I get mad I want to be able to isolate their lan more easily. I hope someone can help me out here :grinthumb

Thanks and just in case, I'm a newbie

Hi, Live many others I've been hit badly by the recent wave of nasty trojans et al very recently. AVG Free (primary antivirus) disabled, installed but now SAS is disabled, MalwareBytes installed but disabled, already had HJT installed but it's been killed too ... will come back for more specific help when I am ready to move on --

Also found at some point were a thru e.exe's and a mbam.exe.

I need to get the system up and running for hubby to jobhut, kids to do homework. This is what we've done and a HJT log. Sorry if post too long, but thought info would help.

Ran CCleaner, was able to eventually run SuperAntiSpyware, Combofix, never got Malwarebytes to run, ran RootReveal and MGtools. Think I have logs to get to you if needed.

I have Toshiba laptop and Win 7. It is brand new laptop and original windows. I tried to install AWUS036H and it was successful but unfortunately adapter doesn't detect any networks. It happened with my old laptop with Win 7(Acer) and I had to reinstall windows fresh and it worked. But I wouldn't like to do it again here. As you may see on picture internal adapter has X in corner and it is working but RTL8187 doesn't, it just says Enabled and nothing happens. No networks detecting. In device manager everything is fine, no yellow icons. Also it is not detected by my ipconfig/all command. The same thing happens in safe mode

Unzip the package and note the location
Uninstall the driver from the device in Dev mgr, remove software if presented (checkbox or prompt)
then update the driver from within Dev mgr using the unzipped inf file

Some reports on the Qualcom board indicate that you might have success with an earlier version, but I only see then on the site I linked.

Try the newest first , then the 255 (270 was the one the poster on Qualcom complained about)

Maybe the Toshiba site has a version that works. My method is to install the base or original driver from the PC OEM support page and work up if the peripheral board driver doesn't help solve the issue.

Is there anyone here that has some solid info/experience using Wifi Sense. \

Me and some fellow network engineers are trying to figure out how big of a security risk this is or is not in an Enterprise environment. We have 40,000 employees, we provide an Aruba wireless network for them to connect their personal devices too and another Aruba controlled network for them to connect to using company issued hardened laptops.

My security team is asking if we think WiFi Sense would share Users credentials from their personal phones/laptops with Wifi Sense enabled and for some dumb reason they turn on sharing.

MS could not even give as a straight answer.

My assumption is that it if Enterprise security is in play that MS would have built in policies to not allow WPA2 Ent type configs be shared?

Our Aruba environment is extremely complex but user Auth is set up such that they provided a 4 digit pass code and the email they use on the website to sign up is the username. Aruba Clear Pass Network.

I am at a bit of a loss and would greatly appreciate any direction and suggestions.

I recently renovated my house and ran all new CAT6 cables throughout. Everything terminates in a closet in my basement, which is also where my Home Office is.

The office houses 6 workstations, MFP and TV with a HTPC. My servers - both office and home entertainment - all sit in the closet in the basement. I have a 12TB NAS along with a number of application servers and web streaming servers.

The home network consists of a few stationary computers, network printers laptops and tablets, as well as three HTPC's that all stream from a NAS server in the basement.

The home is a three floors and due to the length of the runs from the basement to the top floor I opted to save some coin and run a 'sub panel' on the top floor, which is where all the LV cabling terminates just for the top floor (the rest runs all the way to the basement. I have left the choice of wire to 'patch' the two cabinets open and right now it is a single CAT6 wire.

I have rigged it up to work in a temporary fashion with some crude patching and crappy patch cables - all of which I am now on a mission to redo correctly and permanently. The hardware I am currently using is a Arris cable modem connected to a Linksys E4200 for router and WiFi duties, after that I have a Cisco SR2024C 24-port Gigabit switch which splits up all over into a bunch of crappy switches all over.

Question: Two Networks

I work for a small charity that has a network of 7 computers in the office with a broadband connection through a Netgear DG834 routerWe have now been given 10 pc?s that are about 3 years old and we wish to set them up for students to use. They will need internet access and we would like them to connect through the Netgear router. Our problem is that we do not want them to have access to our network. I?m sure I read somewhere that I could use a second router (Netgear RP614) this would allow me to setup the office network behind the RP614, this would be connected to the DG834 allowing office PC?s to still have internet access.This will allow the student machines to be connected directly to the DG834 via a switch.Can anybody confirm this will be okay, or perhaps have a better solution thanks.

Answer:Two Networks

Unless one of those 2 ADSL routers can have the ADSL portion disabled so it will act as a pure Access Point, you will have a problem trying to connect them to just one broadband connection.You can connect an Access Point device to an ADSL router.So for example;ADSL router connects to your existing 7 computers, and a Device acting as an Access Point.The 10 PCs can then connect to the Access Point.I hope they already come with ethernet connections to save your charity the costs of buying ethernet cards, and you the hassle of fitting and troubleshooting any installation issues!Not too sure, but I think the 10 PCs can be setup as a separate workgroup to your existing 7 PCs which will prevent access?

Here's what I have. My desktop pc is a Dell, and it is running XP Home. My internet connection is cable (Comcast).

I also just got a used Dell Inspiron e1505 laptop. I'm not understanding this either. When I go to "system information" it says, its a Dell Inspiron I6400. Is it is the same thing? Also, under RAM it says, "794MHz, 0.99 GB of RAM".... is this good? It doesn't sound like much to me, but the laptop is pretty fast.

Answer:New to networks, need your help please!

Yes, you can install comcast on the laptop, but you can access the Internet with either computer at a time, not both at the same time. If you want to do the latter, you need a router.


Since you have a Wireless G adapter in the laptop, might as well look at Linksys Wireless G router for about $50. You can wire the router to the PC through a network cable. Or buy a wireless card for the PC for about $20.

Go to start, control..., add/remove programs, look for any existing wireless program, uninstall it, restart pc, install the Linksys driver.

Question: Networks

My ISP just installed my Internet they use fiber. There is what they call a smart box in my garage. My home was hard wired when built having 3 connections up stairs and one down. He said he was only responsible for one "hot" wire in what they call the smart panel and i make my connections from there. I should have asked if what he install in the box was just a modem or modem/router. I was going to place my wireless router in the box in the garage but he said to put a switch which I did and was able to have connectivity in all rooms. I further placed another switch in my office to run printers etc all hard wire. I then hooked my router to the switch which worked and provided me with strong wireless upstairs but weak downstairs. I was wondering what would be the best solution for signal strength downstairs, range extender,another router, access point. I considered placing the router in the garage but I foresee the same problem upstairs and maybe not great downstairs as it would be in the garage. Need suggestions. I have an 8 port linksys switch in the box, an 8 port linksys switch in my office and an E4200 wireless router connected to the switch in the office.

Thank you


By "weak", do you mean you are unable to connect? You could try just re-orienting your antenna(s) or adding a larger one before moving things around. If you are able to connect and seem to get a god enough signal, I wouldn't worry about the objective signal strength too much.

You may also be able to increase the power of the router in its settings, but that may only affect transmission. That may be enough.

I have just got broadband and want to use my laptop from anywhere in the house by wireless. I am told that I can attach the adsl modem to my pc but I dont want to have to connect that to the internet before I can use the laptop as I understand this slows the connection. Also my wife has an old 133 mhz laptop which does not have a usb port so could she use a small card thing to talk to a network ? Can someone explain in VERY simple terms what hardware I need and where I should connect it.Thanks.


from the out set lets just say that wireless and simple dont really belong in the same sentence but with patience perseverence and a little help from your friends (here) you should be OK. 1) adaptor,NIC and network card are the same thing. this is the thing that you plug into your machine to enable it to communicate with a network. you will need wireless NICs for your PCs and Laptops (you may run into some serious problems with your wifes antique but I wont be the one to tell you that they will be insummountable)For the PC I would suggest using a PCI wireless NIC and in the laptops you should use PCMCIA cards. 2) Next you will need a router ,Which is a standalone box that acts as the bridge between the internet and your network. having a router will mean that you only have to have the computer you are using switched on (but considerable funds could be saved if this should be an issue, using the PC as a gatway will not slow anything down, the data transfer speeds of even broadband internet connections are very slow compared to local network traffic). I would recommend that you take a look around Dabs, Simply or wherever you like to shop online (or out there in the real world (shudder)) and look for a Bundle deal . Its kind of pointless getting into the details of setting things up right now until you have done you shopping Read The Manuals.

Hello, I am trying to figure out the best way to create two separate networks using one external IP address. I don't want the networks to be able to communicate with each other.

I read about cascading and also read where you get a 3rd router and connect two routers to it. Taking off DHCP and assigning static IPs.

Not sure the best way to go about this and any input from you guys on the most secure way to do this would be most appreciated. You'all never steer me wrong.

Answer:Two Networks One IP

I'm not sure if there are any consumer routers that would allow you to setup two inside subnets, but you could always do this with Cisco (and I'm sure other) hardware. I'll use what I know about this with Cisco terminology, just for the record.

Should be able to take a router and setup PAT (NAT overload) with one outside interface and two inside interfaces, or with a single physical interface with multiple sub-interfaces configured (one for each inside subnet). If you setup two physical interfaces then you could have DHCP running on each and then just connect a switch to each interface. With the sub-interfaces on a single physical port you would need a managed switch with the uplink to the router set as a trunk, then setup VLANs for each separate network.

Not sure if you are asking for home or business, or how much knowledge you have in this area, but it is certainly possible and you don't necessarily need to assign IPs statically.

You can set one of your Win2K pro machines to answer incoming connections, including VPN's. This is straight forward enough as there is a new connection wizard that you can follow.You will then need to make sure that the computer you have chosen has a static IP address and is left on when you want to VPN in from home. When you have done all of that you need to set up your Netgear router to allow the VPN traffic into your network and to NAT it to the IP address of the PC that you have chosen to answer incoming connections. You will need to NAT tcp port 1723 to the ip address of the 2000 box.

I must start by admitting my ignorance about networks, but I see that my PC is suing something called a "Local Area Connection", while both my mobile 'phone and my Kindle reader are successfully using a network connection which involves a password. While this is working satisfactorily, should I rather be using one standard network connection which encompasses the three ? If there is no benefit in this, so be it, but the question is just for my own information.

Answer:Different Networks being Used

You are using the same network except your computer is connected with an Ethernet cable and your mobile devices are connected by wireless. This is a completely normal setup and nothing needs to be changed.

My boss would like me to buy a PCMCIA wireless nic that can be used on 802.11 a, b, and g networks. Does one even exist?

I know G can work on B, but not A.

Your thoughts?

Answer:802.11 nic that can be used on A, B & G networks?

It will have two radios. There are many so called tri band client devices and AP's. Actually it's dual band 2.4 ghz and 5 Ghz) but they support all three 802.11 specs.

Hi. I'm having a problem with streaming movies from my pc (XP service pack 1) to my xbox running XBMC. Here's the deal.

I've been using my pc as a file server for XBMC. Everything was working fine. I could stream without a single hitch.

Then i go and buy a wireless adapter so i could play online with my PSP. Installed the card and after reading a 'how-to guide' about setting up the pc and psp for online play, i ran the home network wizard. It detected all my devices and things were looking good. At first. The internet was working fine. but i couldnt stream movies to my xbox anymore. The connection seems to timeout in XBMC. (My Xbox is connected with a crossover cable to an NIC in my PC by the way.)

Next thing i did was unbridge the connections. That didnt solve anything. So i deleted the connection and re-installed the network card. Still nothing. I re-installed the streaming software (CCXstreamGUI v1.41). Everything is setup correctly but i cant stream anything anymore.

I'm stumped. No idea what to do.

The last thing i want to do is have to re-format, so is there anyway of restoring my connections? (I dont use the system restore feature in XP)

For instance completely deleting the network and starting from scratch?

Dont know how to do it. Looked on google but every tutorial is about setting up a new network. Not getting rid of a bad one.

Answer:When networks go bad!

Just guessing here... Is the firewall enabled by any chance on the NIC going to the XBox?

Question: Networks

So this laptop I was given to fix is all mine now. Toshiba Satellite A100/A105, Win XP Home SP3, Intel Celeron M, CPU 420 @ 1.60GHz, 1.60 GHz 448MG RAM (overclocked to max capability). I will be posting as things come up that I need to know, like this:

Apparently this computer was networked by the original owner. I need to find out how to stop the system from looking for or referring to other computers. There are three references to monitors in the Device Manager: Two 'generic monitors' and one Plug and Play monitor. No reference to this monitor which is ATA. Do I need to reinstall the driver for the chipset before I get rid of those? Thsnks in advance!!!

Jann thinking this is gonna be too much fun!!


I'm surprised you didn't have it completely wiped, as that's normal procedure for computer transfer...
But anyhow, I'd get the latest drivers for everything (if you haven't already.) Create a restore point in System Restore, and then try deleting those two references. Then, if all goes well, install an newer version of the graphics AND chipset drivers.

hello, You have several infections on your system that needs a special treatment, so we can't deal with this in one flow.Any reason why your windows isn't up to date? You don't have even ServicePack1 installed! Remember that your system is extremely vulnerable without the necessary security patches/updates, so malware can get installed automatically while surfing without any problems.Because your system is already infected, updating now CAN cause problems, so let's get you updated when everything is fixed again.You don't have even an antivirus and firewall installed. That's what I want you to do first... Install an antivirus and firewall:AVG, Bitdefender OR Avast are good FREE antivirus.Never install more than one antivirusscanner or firewall on your system!

But, now I am trying to transfer some files from my PC to MacBook, yet I found that the PC desktop still using "bizz1." I should have asked while on the phone, but I did not think about it then.

My whole network keep going down(Wired and wireless), I suspect the reason is that there are too many G networks around me and it is interfering with my router and it keeps restarting to find a usable channel, But because I know just enough to install and secure the wireless router i wanted another opinion. So is it possible that my network keeps crashing because of the many other wireless networks within range( I count 10 right now all G, about 90% secured ).

hi there

yes u can use vpn or some other wan technology ie fibre, isdn, t1 etc

mac addresses are used to filter / restrict machines ie u can lock down dhcp clients by mac address as mac address are unique to each nic

dhcp is ok for a large number of computers because going around manually configuring machines would b a nightmare, also manually is prone to typing errors. but for things like servers or port forwarding then a manual address is required

hope that helps

I have 1 NIC and say i set to static on a 192.168.1.x range.

I also have a phone system usinf 192.168.42.x range.

I use a seperate program in windows to configure the phone system.

Is it possible for the NIC to have 2 subnets assigned. eg with the switch configuration as static as default VLAN and phone on 802.1Q VLAN, can i set windows up to accept tagged packets through the trunked VLAN?

Anyone done anythign like this before?


Answer:1 NIC with 2 networks

Each network interface can only attach to a single network at a time.

192.168.42.x seems like you're using the phone as a wifi/usb modem, can it be?
If so, the phone itself will become a second NIC with its own configuration and IP address, thus the computer will be part of 2 networks.

Good Morning [H] (or afternoon, evening and goodnight),

I'm renovating my home, rebuilding the basement, and now is a good time to upgrade/fix my network. I'm pretty rough in my network knowledge, but would like to do this right.

I have a 100mbs cable connection (can upgrade it to 150) and run 5 hardwired connections, and 7 wifi devices. The asus router I use struggles to keep up sometimes, and is particularly hard on my PS4.

I'd like to upgrade the system, switch over 2 of the wifi devices to hardwired, making 7 hardwired and 5 wifi devices (phones and tablets mostly).

My home is wired with Cat 6 cabling, and is 1200sq/ft on the main floor, 1000sq/ft on the second floor, and the basement will be roughly 800 sq/ft once done. Router is currently at the back of the house (worst spot ever) but I'll be moving the wifi component to the middle of the house.

From the back of the house, the wifi just barely reaches the front, so middle should be fine.

What kind of system do I need, I'm guessing switch + router? Should I be separating my WIFI from the main network as it only runs mobile devices and the guest devices (I heard that the slowest thing connected slows the network)?

Thanks for your help!

This router is working fine with an IBM laptop , a Dell laptop and an old PC - all on Windows XP. I have purchased a brand new pc fitted with Windows 7 x64 and because my old wg111v2 adapter doesn't yet have W7 support, on the advice of the Netgear tech support I bought a wn111v2 and downloaded the latest drivers for it.

Is there any way to set up both a wireless WAN and a wired LAN on a group of PCs running WinXP and WinVista so that each system can transfer files simultaneously via both WAN and LAN?

Weve had a wifi network working fine on a group of PCs, but in order to enable faster file transfers between systems, weve put 10/100 LAN cards in each PC and have wired them through a separate router.

The network gets its Internet access through a wireless router set to an IP address of connecting wifi adapters in each PC. Now were trying to set up a secondary network via LAN through a separate wired router set to an IP address of connecting 10/100 LAN adapters in each PC

However when connections for the LAN adapters are enabled in XP/Vista Network Connections, it kills the wifi connections. The systems will only network with one type of adapter enabled in Network Connections at a time, wifi WAN or the wired LAN, but not simultaneously.

Is it possible to have the systems set up to access the Internet and transfer files via the wifi WAN, and at the same time enable faster file transfers through a secondary wired LAN?

Thanks for any feedback.

Answer:2 different networks, WAN and LAN on 1PC?

You probably have the default gateway entered for the TCP/IP properties for the wired NIC. You do not need to add a default gateway for this subnet as you're not looking to route outside of it. Windows takes the wired NIC's properties in terms of default gateway routing as the higher precedence over the wireless NIC as you cannot have two default gateways....(well shouldn't unless under very specific circumstances.)

Also, I assume the is a typo and should read

Ok so me and my neighbor are trying to come up with a way we can "share" a seedbox. I have the crappy cable internet ( but with 3 kids, Im always broke) and he has pretty good DSL (thats truly unlimited, unlike my cable) What we would like to do is have one box both networks can use, sort of a shared folder. The deal is, if I admin the box. His IP ranges are in the range and so are mine. So basically, what I am trying to do is have a box on both networks, BUT all downloading has to done off one network.

I was playing with this before, using a wired 10.0.0.XX and a wireless 192.168.1.XXX address and if I remember correctly if I manually set the 10.0.0.XX address to use as the default gateway it wrkd. ( and I may very well be remembering wrong as I only did it once and it was a long time ago.)

I believe the issue is that were both using the 192.168.1.XXXX range where BOTH of our gateways are at So for this to work Ill have to go to the 10.0.0.XX range or some other, correct?

So I now know not to trust family when it comes to laptops. Recently a brother-in-law asked to use my laptop to send an email (this was about a week ago) now I find that he has installed his own network on my laptop. Oddly enough he didn't ask permission to do so. And I was under the impression that he only wanted to use it just once. So my question is can I remove his network by re-installing Windows 7? He is in college and isn't here now and I don't know when the next time he will be here. And NO I really don't care what he has put in that network. He did it without permission... So all is fair as they say... But alternately is there another way to remove this illegal network from my system. Clearly I can't get him to do it. I don't trust his word anymore... Thanks... Leonard P.S.: Is it possible that he can access my laptop from anywhere he happens to be? I don't see his name in the area marked NETWORK now.... I really need help to rid me of this problem... Thanks again
