How To Install BCM43XX Driver On Ubuntu 11.10

After building my own kernel (version 3.2-rc7) i had some problems with installing the driver for my WiFi card. The card i have in my laptop is the following: Broadcom Corporation BCM4312 802.11b/g LP-PHY (rev 01). I tried to install the driver using the Additional drivers menu but when installing i got a message that the installation wasn’t possible and to check the jockey.log. In the log file i noticed that the card is “blacklisted” and after removing it from the blacklist.conf it still wouldn’t install.

So after some searching on the internet i found a way to install the firmware. To download and install the needed files open a terminal window (press Ctrl+Alt+T) and copy+paste the following lines:

cd ~/Downloads/



When download extract the broadcom-wl- file using the following command:

tar xfvj broadcom-wl-

To install the firmware:

sudo b43-fwcutter -w /lib/firmware wl_apsta-
sudo b43-fwcutter --unsupported -w /lib/firmware broadcom-wl-

It may take some time before the wireless networks are detected and in the worst case you need to reboot your system.
