How to fix the Broadcom 4311 (BCM4311) 802.11 a/b/g WiFi/Wireless chipset driver and get a perfectly working Wireless Network Connection on Ubuntu 12.04 / 12.10
The Broadcom Corporation BCM4311 chipset (usually found on many HP dv9000 series laptops) has some issue working on Ubuntu 12.04/12.10.
You can use the following procedure to get it working fine:
Before you start on this, first check whether you have the correct Wireless Chipset we are referring to:
In Terminal, issue the following command:
lspci | grep BCM
and see whether the following line shows up:
03:00.0 Network controller: Broadcom Corporation BCM4311 802.11a/b/g (rev 01)
If yes, you can proceed safely to ensure a working wireless chipset.
Step 1: Remove the current BCM driver (standard SAT) in the kernel:
Terminal command:
sudo apt-get remove bcmwl-kernel-source
Step 2: Install alternative drivers:
Terminal command:
sudo apt-get install firmware-b43-installer b43-fwcutter
Step 3: Restart Ubuntu.
Voila! You should now have a working Wireless Chipset all ready to connect to your favourite Wifi. :-)
Let me know via the Comments box below if you still face any difficulties. I'll try my best to help you out.
Cheers,
Anto
P.S.: Here is an alternate method I found here: http://ubuntuforums.org/showthread.php?t=2136081&p=12605716#post12605716
Terminal Commands:
sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
sudo modprobe b43
