i bought this wireless card BCM94321MC because i saw several people who said it worked instantly without any drivers. For me i'm using Ideneb 10.5.8, and it is reading it as an apple airport card, it does scan and find wireless SSIDs, but when i try to connect to any of them it just says connection failed, i tried repairing permissions, any ideas?

Does the card itself work? I bought one of these cards off eBay (supposedly new) only to find that it could receive only, no transmit. Exact same symptoms as yours. I would verify under Linux or XP that the card actually functions before going any further.

Yeah, should have mentioned that i can use it with Windows 7. It automatically read it and it seems to work fine. Just doesn't work on Mac
