I am using a Linksys Router, (WRT54G), and a Linksys PCI Card, (WMP54G). On my old PC I was running XP PRO, on my new one, I'm running XP Home SP2. I took the wireless card from my old PC and installed it on my new one, loaded all the same drivers but I cannot get it to connect. I see the signal strength, but when I try to connect to it, I can't. I've tried both letting windows configure my wirless connections and letting the Linksys utility do it. Neither will work. Just to make sure I wasn't crazy, I took the card out of my new PC and put it back in my old PC and it worked just fine. Do I need to maybe upgrade the firmware on my router to accomidate SP2??? Please help....
