I have a Pentium 3, 733 mhz, 384 RAM, running Windows XP SP2 with the latest BIOS that I'm trying to get working with my WMP54GS card. It freezes after or during the time I'm installing the drivers for it. Sometimes it'll even freeze on the Windows XP startup screen when I have the drivers for the card installed. It does this even after a format and fresh install of Windows. It won't freeze if I turn off Linksys wireless software quick enough and switch to Windows XP WIreless utility, but then I get the error saying it can't find any networks and to make sure the wireless switch is turned on. It's a desktop so there is no wireless switch to turn on. The same WMP54GS wireless card works fine when I install it in another computer of mine and they both sit in the same place. This one's a Pentium 3, 498 mhz, 384 RAM, running Windows XP SP2. I recently tried installing the broadcom drivers from this forum and the PC freezes during the installation. Then when I start the PC back up it has a yellow exclamation mark error on it in the Device Manager. I've also tried using the broadcom utility while having Linksys default drivers installed and I get an error saying the wireless radio isn't on, similar to the error I get with Windows XP Wireless utility about the wireless switch being turned off. I had also formatted and reinstalled Windows XP SP2 before installing the broadcom drivers. Of course the broadcom drivers and utility worked fine both ways on the computer the card was already working with.
