How to enable broadcom wireless BCM4311 card on Linux Mint 11
This will be very quick and useful tutorial for people who try to install proper driver for broadcom wireless cards on Linux Mint (it probably works on Ubuntu and Debian like distributions). There are two drivers for broadcom wireless card on Linux. One is STA driver which is proprietary and the second is b43 open source driver. I have installed Linux mint 11 and get problems with enabling wireless using STA driver. It does not work for BCM4311 cards and you need to install b43 driver. Here is the solution.
sudo apt-get install b43-fwcutter
b43 module is blacklisted by default you need to comment out that line.
sudo vim /etc/modprobe.d/blacklist.conf
Put comment on line with following content
To avoid whole system restart, just restart b43 and ssb module
sudo modprobe -r b43 ssb
sudo modprobe b43
Click on your network manager to and wait a second to load all available networks. Enjoy!
