We have installed many Aironet 350 cards in W2K and NT laptops with no problem. Our CIO has a Compaq tablet running XP. I have disabled the onboard Intel card and the 350 seems to be installed OK and functioning. We use static WEP,128 bit. The tablet 'sees' the AP for approximately 6 seconds and then we lose association. The 350 status and activity lights continue to flash normally but link status and site survey on the client do not see any association. Any ideas ?
