I installed the b43 drivers and everything just as it said how to for the 9,2 macbook pro and everything was working fine for a few days. Today i decided to boot into my OS X partition and when i booted into ubuntu my wireless card is still there but now it can't find any networks. I tried connecting to my router manually but it never connects and continuously asks for the password. I tried re-installing the drivers but it's still a no go. Any help would be appreciated.
