sudo modprobe -r b43 bcma
sudo modprobe -r brcmsmac bcma
sudo modprobe -r wl

sudo apt-get purge bcmwl-kernel-source
sudo apt-get update
sudo apt-get install firmware-b43-installer
#without connection: those drivers are on the install medium (at least for ubuntu 14) one might need to add it to the list of repositories
#when the last line crashes and it tells to run "apt-get install -f" and "dpkg --configure -a" which crashes again: 
#> sudo dpkg -r -a
#allows to make apt-get work again

sudo modprobe b43
