I am positive that my Chipset can use the B43 Driver. I am running Ubuntu 12.04 on Kernel 3.2.0-33. I am currently, unfortunaly running the brcmsmac driver.. When I try to run "modprobe -r brcmsmac bcma" to disable the current wireless driver, it does. But then when i go to replace it with the b43, which i already installed using the fwcutter-installer by typing "modprobe b43" it doesn't do anything. It doesn't work. So, can someone please help me get the b43 driver to work..
