After installing a USB PCI card on an older computer running Windows 98, the network card has stopped working. I had to unplug the network cable from the back of the computer in order to be able to pull it out from the wall a little bit to get some access, and that is all I did concerning the network in general. After that I installed the USB PCI card, put the case back together, plugged the network cable back in, plugged the power card back in and restarted the computer. Of course, upon restarting, the computer recognized the new hardware and installed the drivers. However, it never asked me to log in to the network. From that point on, the Device Manager does not show my network card. WTF?
