I have a cable linking the computers together. The other local area connection says unplugged. I was told all I have to do is plug it in, use install wizard and all would be good to go, not the case. Even in the install wizard it tells me the cable is unplugged. I know the cable and the NIC cards are good. I have a connection to the host computer when I switched cables from one ethernet connection to the other. Anyways, I am using WinXP and SBC Global Internet connection. Any help would be appreciated.

I don't know what this "COM" you keep saying is, but if you are running a single ethernet cable straight from one PC to another, then you need to make sure its a CROSSOVER cable. Otherwise you'd have to stick a hub or switch inbetween the two.

I think you are referring to ethernet... this is a cat5 cable.\n\nYou will have a jack(hole) on the side or back of the laptop that looks like, but is a hair bigger than a phone chord.\n\nor right click on "my computer" go to properties and click on device manager. You will see all devices there along with any issues you may be having like drivers not being installed.

Make sure the connection is sharing an internet connection. Check that the xbox setting are correct in the networking area. if the u  have a modded xbox, its possible that the chip has disabled the nic on the xbox. \nCheck the cable make sure it is not broken.\n\nMy ? for you. why dont u get an inexpensive router to make things easier when trying to network?

First off we need to know what kind of router you are working with.  Please provide the model and make, along with the kind of internet service you have.  Also what operating system you are on would be helpful - Windows XP, Mac OS X, etc.  \n\nThe first thing do when you hook up a router to your DSL/Cable Modem is to turn all the equipment off.\n\nPower down the computer, the DSL/Cable Modem and your router.  Its best to physically remove the power cables from the modem and the router to ensure that electricity is not keeping any memory chips alive.  Make sure you plug the ethernet cable from the DSL/Cable modem into the routers WAN/internet port.  Then make sure your computer's ethernet port is plugged into one of the routers LAN ethernet ports, they are usually 4 ports right in a row on the back of the computer.  This should fix any problems with hooking up the cables physically, and now it up to your network settings on your computer.  In order to help, please provide the information I asked for at the top of this message. \n\nThanks!

I'm not sure who sells 50 foot crossover cables (you can use a short crossover cable with a cable coupler and a long "normal cable"), but I can tell you when to use them.\n\nBasically, the wires in a standard ethernet cable run straight through - pin 1 on one end is pin 1 on the other end.  The problem is that the ports on your computers have "in" and "out" wires (actually, transmit and receive).\n\nTo connect to "things", you have to swap the "in" and "out" wires.  Most hubs/switchs/routers do this for you automatically INSIDE in their wiring.\n\nBut, if you direct connect to computers, something has to switch the two wires.  That's when you use the crossover cables.\n\nOne more note.  If hubs/switched/routers swap the wires of the cable, how do you hook two of THEM together?  One would swap the wires and the other would swap them back.\n\nTwo things.  Newer switches/hubs have "smart jacks" that detect whether or not the wires have been swapped and swap them dynamically.  Older ones have an "uplink" port, that does NOT swap the wires.\n\nThus, you can use a crossover cable to also connect two hubs/switches, providing you do NOT use the uplink port.

The gist of the message is this: \n\nAnswer \nMicrosoft Windows XP has built in support for 1394 Networking. In addition to loading a driver for the 1394 adapter, Windows also loads a networking component that allows computers to be networked via a 1394 cable. \n\nRarely will the installation of the 1394 Net Adapter interfere with the currently installed network setup. But there are circumstances where this might happen. \n\nTo resolve this issue, we suggest that you perform the following steps: \n\n\nRemove the 1394 controller and then use System Restore to get the system to the previous state. \n\nNext, browse to c:&#92;windows&#92;inf and locate the following two files: \n\nNET1394.INF & NET1394.PNF \n\nDelete both files and reinstall the 1394 card. When the system boots up, it will prompt you for a driver for a 1394 Net Adapter. Cancel the installation for the Net Adapter. \n\nNext, go to Device Manager and look under the Other Devices category and you should see a 1394 Net Adapter with a question mark. Right click on it and choose 'Disable.' \n\n\nThese steps should disable the 1394 networking function and will stop the initial loading of the device but will leave the controller enabled for attaching 1394 devices. This change should not impact the general functionality of the 1394 adapter.

To start off with.  Are we 100% sure that these devices are routers, and not switches.  8 port routers are not uncommon, but not as common as 8 port switchs. \nIf it were a switch, and only one computer was grabing the ip address from the modem, that would explain why only one computer could get online at a time.  I have seen switchs work with two computers for a short time before.  Afterwards, you will get a message, "Limited or no connectivity"  at the bottom of the screen.  Also, if anything has changed, that would be helpful to know.  Did you just switch from Cable internet to DSL?  Or did you change out the DSL modem?  If the DSL modem was changed out, and not put in what is called bridgemode, this problem may not come up as an issue until all 3 computers are actually on and trying to access the Internet.  (Putting the modem in bridge mode tells the Router it is in charge of establishing the credential info w/ ISP, not the modem.  If modem is in charge of this, it may only have the ability to handle one computer on the Lan side of the network.)\n\nLet's start off and assume that you do have routers.  Here are some things to check:\n1.  is the router plugged into a Uninteruptible Power Supply? (I have seen many drop off and connection issues solved with this little piece of heaven.  I know you are sceptical about purchasing new hardware, but this should be a pre-requisit for all devices that have any kind of value.)\n\n2. If you are cabable I would read the instructions for your router, and reset it back to factory settings.  You may want to write down the existing settings before you do this.  (if it is connected to DSL, your username and password, Cable, if it is a static or DHCP wan address etc. etc.)  Once back up and running, download the latest firmware from the manufacturer.  This would require Internet activity.  \n\n3.  As was stated earlier,  let's connect each computer directly to the back of the modem and check for connectivity.  (If the modem was previously set to be in Bridge mode, you will have to change it to be in charge of handling the logon creditials.  This usual setting is PPPOE)\nOnce the computer is connected to the modem, you need to power cycle the components so that they grab new IP addresses from each other.  Power off Modem and computer,  plug modem in first, let all lights quit blinking then power on computer.  If computer is unable to connect, it could be modem issue.  But let's not rule out other things.\n    a.  Check the network settings on the computer.  Right mouse click on My Network Places and go to Properties.  From there right mouse click on the Lan Properties and go to properties there.  Click on TCP/IP and hit the Properties button there.  Check to make sure the adaper is set to obtain IP address automatically.  And the DNS the same.\n\n4.  If all computers are set to obtain an IP automatically as described in step 3-a.  and they are hooked up the a factory default router, with known good cables, they should be able to at least ping each other.  Disable all Norton Internet Security, and Macafee Internet Security and Zone Alarm (Some of these actually block ICMP request so we wouldn't be able to ping the computers)  Go to computer 1 .  Start --> Run. type  CMD and hit  enter. type "ipconfig /all"  leave off quotes  write down the ip address that it assigns you.  If you have the Linksys router setup, and it is set to default factory settings, it will probably assign you an address of 192.18.1.100 or close.  Go to another computer.  Start --> Run  type "cmd" and hit enter.  type "ping 192.168.1.100" or what ever number that was listed.  if you get a reply, that means you are able to pass traffic through the router to the other computer.  if you get request timed out that means you are not able to connect.  \n\n5.  If after reseting the router to factory settings you are unable to ping the other computers on the network, but

Usually they will have a flashing light on it even if it is a onboard NIC card you will see a light flashing in the back of the computer!! Check the cord see if it is broken (this happened to my father last month) if you can borrow one try that and if it works buy a new cord. RJ45 cord at Radio Shack set you back about 5 bucks. The other thing is open the control panel,open system,open hardware, open device manager,in there you should see one of them that says network adapters that is the NIC card.If you do see it click on it and it will tell you if it is running properly.If you dont see it then more than likely it might have deleted the driver. Which if it is a plug in NIC card just take it out and restart the computer so that it will clear itself. Then turn the computer off and put the card back in and start the computer back up pnp should pick it up and ask if want to install it click yes. If you dont have the install disc click on search MS ,and the C drive hopefully between the 2 it will find a driver. If it does it will ask if you want to install it click yes again once itstalls restart the computer. If it is a onboard card open system again,hardware, then hardware wizard. When that opens click next,make sure the box that says ADD?Troubleshoot is checked then click next it will do a search and if it finds it you just do the same as if it was a pull out. If it cant find it a choose a hardware device box. Look in there for something that will say ethernet controller (NIC) then just install from there. And restart the computer. Some computers have one that plugs into the usb port. Basicly you would just have to unplug it.If after all of this it still doesnt work the more the likely you need a new one. You can pick one of the ones that plug into the usb port for about 15-20 bucks.\n\nGOOD LUCK\nZEUS\nP.S. While I was writing this JonW hit it on the head!!!!! between both our info you should be able to fix it Thanks Jon\nZEUS Comptia A+ Certified in computer repair,building,and troubleshooting Certified in Computer Networking for 6 years!!!

When you use an Ethernet cable to connect your computer to a hub, switch or router, you use what's called an MDI (straight through) cable.\n\nIn order to connect one computer to another directly, you must use an Ehternet cable with a different pinout called an MDI-X (cross over) cable.\n\nThe reason for this is because your computer is a "terminal" device.  It transmits data on a specific wire and expects to receive data on a specific other wire.  Then you connect it to a "host" device and it expects same thing, but on the opposite wires.\n\nFor more information, see the article on Ehternet on howstuffworks.com\n\nhttp://computer.howstuffworks.com/ethernet.htm

My guess is that your modem only allows one method of connection - either USB or ethernet, not both.  You say in your question wireless router, do you have 4 ports + the one internet port on the back, or just 1 port?  If you only have one, then it is just a wireless access point.  If it is a wireless router, you would be better off placing the modem in bridged mode and running everything through the router.  However, in one of your updates, you mention that "the broadband controller has some problem" - do you mean the network connection on your computer?  You might try reinstalling the drivers and see if that takes care of the issue.

have you called their support number (1-877-722-3755)? for intermittent connection --- there might be some problem with the line. have you asked them to have a line check? there are some process or troubleshooting they could give you to have it fixed... and it should be the line dept. who needs to check it for you. its not only on SBC server but also they need to check on your area, where there might be some circuit problem.

First the difference between a switch and a hub is kind of hard to explain over email postings so just know that a switch is much faster and more reliable then a hub. \n\nFirst go to each computer left click the "My Computer" icon then right click each drive you want to share. More then likely there is only one hard drive, which is called the C: drive by default. After you right click that drive go down 4 lines to were it says "Sharing and Security" and left click it. Then put the curser over the "Share this drive" and left click that one and then give it a name...whatever you would like. Don't worry about any of the other stuff. Click OK. If it works a picture of a hand will immediately appear under the picture of the drive almost like it is holding up the picture...you'll see what I mean. That is the first step and will make all the computers ready for file sharing and do this to all 3 computers. NEXT\n\nGet a CAT5 cable for each computer and plug it into the back of each PC. I assume there is a network card in each computer (almost ALL new computers come with one now that is built onto the motherboard) but the way you can tell is to look in the back and see if there is what looks like a telephone plug in. Don't be confused because a network plug in (called a RJ-45 connection) is bigger then one for a land line phone line. I will assume that you have one. The next thing is to figure out how long the distance is between the computers and the switch. With CAT5 cable the maximum distance is 300 meters or 320 feet. So as long as you are under that distance you will be fine. Plug all the cables into the computer.   NEXT\n\nHere is the problem… you only have one IP address from your ADSL modem. Either you have to have a router to share the connection (giving each computer a IP address) or setup Windows Internet sharing on one of the computers, which I can walk you through if you would like. This is THE ONLY WAY IT CAN BE DONE...unless your modem has a router built inside as most do now days...if you send me the make and model I will look it up for you!\n\nI am the system and network administrator for 4 major car dealership in charge of 75 computes and many different kinds of networks so I know what I am talking about. I would be more then happy to help out any more so let me know if there is anything else I can do….

unless there is software that tracks your patch panel (very unlikely) then the only way is to physically check. why do you need to unplug the cable anyway? you can still trace while they're still plugged in.

Are you losing the connectivity from the computer or the ISP? Do you have a Modem and are the link lights on or off (and do they stay on when you try to connect).  You need to start at the source and work to the computer to define the problem.  First be sure of connectivity to your Modem or router -- If this is Okay then replace the cable (cheap and quick) if all is well to the computer it must be in the computer setting -- the best place to start is searching network connection problems and following the direction to investigate the problem.   If you are using "cable" internet those thinks need to be reset all the time under certain circumstances (power everything down for 3 min. and start powering up from the source)

Do this: Start-Control Panel-if not in classic view, change to classic view, then double click on System. In System, click on the Hardware Tab, then click on the Device Manager button. A window will pop up, this is your Device Manager. Now, you should have a list of Hardware which is installed on your System. Browse down the list and look for Network Adapters. Click on the "+" sign to open and read the entries there. If there is no listing for Network Adapters, which there should be as you should have an Ethernet Adapter as the very least, then you do not have any adapters installed. That would be a rare case indeed. Now, the Ethernet Adapter will have either a 10/100 or 10/1000 desription, depending on how new the computer is and if you paid for an upgrade in the Ethernet Adapter. Look for a listing which is not designated as 10/100 or 1000, double click to open Properties and read the desription. You may also have your FireWire listed there, even though it is not really a Network Adaper. FireWire will also be listed in your Network Connections too, why I am not sure, but that is how Windows handles FireWire right now. So, FireWire is 1934 IEE, which is not a Network Adapter. \n\nThe above is the best way to see what you have installed on your sytem. This will also tell you if it is working correctly. When you open Properties, down in the first Tab is a small area which will tell you either "This device is working properly", or "This device is not working". \n\nOnce you know what you have installed you can move forward with using it for Networking. \n\nGood luck and have a great day!

Sounds like you have a bad NIC in your PC.  If the modem works with other computers, its probably OK.  Sounds like you tested cables well.  \nDo you have more than one device hooked up to the modem?  if so, certain models may require a router in between.  \nWe did even talk about your networking settings at all.  Enable DHCP in your modem.   Set PC to Dynamic IP.\nIf all doesnt work, purchase a new ethernet card for your PC, install it, and if it still doesnt work, take the ethernet card back to best buy for a refund.  Its all good baby.

Hi, Here are a few things to try..\nCheck your connections (cable, NIC, router) Does your NIC have a connectivity light on it? most have a light that shows connectivity and traffic. If there is no light on check your cable. Does your router have connection lights? Check that as well. Try hooking your NIC into a different port on the router. Look in the DHCP settings of your router and see what the range of addresses are being assigned. It may be set to only assign a few.\nIf you are using a static address, you must make sure you are using the same Sub-net mask, address pool &  gateway as your other systems on your Lan. If you know all this is good, then  make sure you have updated drivers for your NIC, you can also try uninistalling TCPIP and re-installing it.
