sudo apt-get install b43-fwcutter firmware-b43-installer sudo gedit /etc/modules
add "b43" without quotes at the end of the textfile, note you can only use one module per line.
sudo gedit /etc/modprobe.d/blacklist.conf
add "blacklist wl" without quotes to keep the wrong module from being loaded on boot.
