Hi I was looking for the same answer and found a way to make the card work with XP. Looking at the FCC number on the card, it appears to be the same card as the Proxim Gold B/G cardbus card. The main difference appears to be the PCI id used in the .inf file for the driver. I made mine work in XP by changing the references to the string PCI\VEN_168C&DEV_0013&SUBSYS_04101468 in the latest drivers .inf file to the string PCI\VEN_168C&DEV_0013&SUBSYS_AA3014B7 . Hope this helps. JJ
