Wireless Driver issue in Ubuntu 9.10 for Compaq CQ40

Posted by Bala on December 10, 2009

On Tuesday night I installed Ubuntu 9.10 on my friend’s Compaq CQ40 Laptop. The installation went fine and there was no issues. Most of drivers got detected automatically and everything was fine except the Wireless LAN card. With “lspci” command I found the name of the Wireless manufacturer as BroadCom BCM4312 802.11b/g. Then with help of my junior Senthil Kumaran S, we found that we need to install bcmwl-kernel-source which is available in Ubuntu Repository and a restart of the system made the Wireless card to work properly. Thanks to Ubuntu Forums for pointing out this in the below mentioned thread.
