I built a PC a few years ago and recently sold it to a friend of the family. When I did so, I done a clean install of XP, installed SP3, and set up the wireless card so wireless worked fine for networking etc. I had no problems with the network side (wired and wireless) whilst I had it.
PC was installed at their gaff. They don't have wireless and they said plugging the wire in didnt work. So, I went round, uninstalled the wireless card (just in case of any conflicts), installed the (nvidia) drivers for the built-in Ethernet port on the motherboard. Now, it picks up the network port, and detects when I plug in the wire. It then spends two minutes or so trying to acquire a network address, before eventually finding one. However, the internet doesn't work, and when I type in ipconfig it doesnt show any setting for the gateway address (which is the router address I believe). Also, when I plug in the network cable and it's trying to get an address, it sends very little data, basically 2 bytes at any time.
Any suggestions on how to fix? Motherboard is a Gigabyte K8N S939 SLI if that helps.
