It doesnt look like a Vista driver was ever made for this wireless card, so I installed the XP driver in XP SP2 Compatibility Mode. I did this with my video driver with no problems. Now it says my ZyAir card is installed but it wont see any avaliable networks (it should be seeing two wireless networks). If I manually put in the SSID and such, it just says that it cant connect to that network. What kind of hoops do I need to jump through to get this to work? I am not vary familiar with the Vista OS's, so it could be that I am just missing something. I am running an HP Pavilion 533w which I just upgraded so that Win7 would run on it. The ZyAir B-300 is not the wireless card that came with the computer. It worked fine under WinXP.
