I recently had cable internet installed. I have three computers that had not been networked before. I bought a Linksys BEFW11S4v2 Router and two WMP11 Wireless PCI cards. The router is connected to a computer with WIN XP and one of the PCI cards is connected to a computer with WIN XP. These both work fabulous. However, the third computer has Win2000Pro and I cannot get the PCI card to install and hold in memory. I have physically reinstalled it several times as well as uninstalling and reinstalling the software. If by luck I get a signal, as soon as the computer is rebooted everything is lost. Linksys has been somewhat helpful, but we haven't resolved anything. They suggested the card is bad and that I return it to the store. I took it out of the computer and swapped it into another computer and it worked fine, so I doubt if it is the hardware. I have downloaded their updated firmware driver and all it does is crash the computer. Does anyone have any advice for me? I would so much appreciate it.
