Many Linux distributions do not provide functional drivers for Broadcom Wireless chipsets (e.g. BCM94311MCG). This is the case starting with version 11.10 of Ubuntu and its variations (including Linux Mint). Here is how I got Wireless working:
- Remove the installed STA drivers:
sudo apt-get remove --purge bcmwl-kernel-source
- You may need to also remove the corresponding configuration files, if they exist. Run these two commands as well:
sudo rm /etc/modprobe.d/blacklist-bcm43.conf sudo rm /etc/modprobe.d/broadcom-sta-common.conf
- Install the B43 driver:
sudo apt-get install b43-fwcutter firmware-b43-installer
