A friend brought over a computer for me to remove a virus, after checking out the computer found that the OS was hosed. So backed up data, and put a fresh istall of XP pro on the PC, legal copy not bootlegged. Couldn't get ethernet working, figured since he did have a several nasty viruses, I'd flash the BIOS, and right 0's to the drive just to make sure no nasties were still on the machine. All said and done, reinstalled XP Pro, on an Emachine T2862. Installed drivers. Installed a pci 3Com ethernet card, with the right drivers. No ethernet, cant get an IP, tried using a good static IP didn't conect to the internet, couldn't ping the router. Plugged in a Linksys wireless usb adapter, grabbed an IP right away. Tryied plugging the ethernet in, ethernets get IP's now, unplug usb and ethernet stops working. Plugged usb back in did all of the windows updates, including hardware. Tried Ethernet with the new drivers, still doesn't work. Tried Winsock fix, tried XP bat fix. Any other suggestions, I'm stuck.
