broadcom-sta
Sources for my customized broadcom-sta ubuntu package, supporting CFG80211.
For more information, read "Why Broadcom 802.11 Linux STA driver sucks, and how to fix it".
Ubuntu packages are available in poliva/pof ppa:
sudo add-apt-repository ppa:poliva/pof
sudo apt-get update
sudo apt-get install broadcom-sta-dkms
You might want to remove the old wl module first, if you have it installed:
sudo apt-get purge bcmwl-kernel-source
