I have been emailing linksys back and forth trying to get this to work and so far they can't figure it out so I would figure I would come here and ask the real experts! I work in a tech support office where we use wpa2. Everyone has a laptop with a linksys wpc54g card. I went out and bought the same exact model for my personal laptop as I have not recieved a work laptop yet. I have downloaded the latest drivers for the card, I have even tried all the versions associated with the card. I have downloaded and installed KB 917021 and KB 893357 from microsoft and I still cannot use wpa2, with windows or with the connection ultility. I have WinXP Pro. If you could be of any assistance to me it would be so beneficial to me right now because I am stuck in the office on Christmas with nothing to do!
