The STA driver does not work properly for the BCM4311 in Mint/Ubuntu/Debian.
The Restricted Driver Manager only gives you the Broadcom STA driver as an option.
Yesterday got asked by a friend to remove Ubuntu from his 5-year-old laptop. It’s a 64bit, 1Gb Ram machine, with an Nvidia graphics card and Broadcom wireless.
I was pretty certain that the 64bit Linux Mint 12 would just work out of the box, even though i’ve had problems with the Broadcom firmware on other machines (wireless cutting out and needing to be restarted)
The install went fine, and I went straight to the “Restricted Drivers manager” for Nvidia and Broadcom. The STA driver was recommended so I installed it. Only to find it would work.
My laptop at home works ok with the older B43 module, so I went the traditional route and installed that instead.
sudo apt-get install firmware-b43-installer b43-fwcutter
Then unload both modules:
sudo modprobe -r b43 wl
Now reload the B43 module:
sudo modprobe b43
If when you reboot, the B43 module doesn’t get loaded:, just add it to “modules”:
sudo vim /etc/modules
and add b43 at the end of the list. Now it’ll load at boot.
The STA module may also load at boot, so just blacklist it by adding it to the blacklist:
sudo vim /etc/modprobe.d/blacklist.conf
and it like this:
Now reboot, and you’ll have Broadcom 4311 wireless working.
