WIN XP PATCH CORD not detected

February 12, 2013 at 21:03:23
Specs: Windows 7
I have a Windows XP desktop that I've never had a problem with and I've had it for a long time, and now it says that my "network cable is unplugged" (yellow Patch cable) even though it clearly is, I have gone to many a Forum, wiki, yahoo answers, etc... but none of them have helped (or even replied) and I have a very important project due soon and I NEED my computer, so if anyone could help me it would be GREATLY appreciated.

Most probably the network card has failed and needs replacing.

Windows can't tell the difference between an unplugged network cable and a broken network card, so it just gives you the same error message for both.

Or it could even be as simple as a cable gone bad. Do you have another one that you can try? It could just possibly be your router/switch, but that's the least likely cause. Anyway, network cards and cables are not very expensive so it's easily corrected.

You might just want to try reinstalling the driver for your network card before spending money; otherwise I would just buy a new network card and cable (it's always useful to have a spare cable in any case), disable your built-in NIC in the BIOS (if it is built-in), and install the new card and drivers.

One way to check if it is the network card is to go to a Command prompt and type Ping 127.0.0.1. If you get a response it means that everything is working correctly up to and including the network card. If no response then the fault lies within your computer. Renewing the network driver would both first thing to do.

Assuming that then networks card is working check that the Link light light up when the cable is plugged. This is a light on the network interface that lights as soon as cable is plugged and at both end.

@StuartS. I'm 99% sure that 127.0.0.1 doesn't touch the network card. It uses the loopback interface and can work even if there is no NIC. Pinging the computer's own address will test the NIC (I think), but is only really useful if the computer is set to a fixed IP address.

"network cable is unplugged" (yellow Patch cable)"

Is this a different cable plugged in recently?? The reason I ask Is that a yellow patch cord is quite often a crossover cable (as denoted by the color). This is not always the case but quite often is. Have you tried replacing the cable?

There is not colour coding at all for the outer sheathing and Cat5 cable. The colour is just for identification in a network switch box. Nothing else.

Network cables come in many different colours but inside they are all the same. A crossover cable can be any colour that is available at the time it is made.

Almost all (?) routers and switches are auto-sensing nowadays in any case.
