Ubuntu 11.10 getting wireless BCM4311 working

I have an HP laptop model nx6325 with a Broadcom BCM4311 wireless card.  After installing Ubuntu 11.10, I find that my wireless doesn’t work.  The reason, Ubuntu detects the wireless but then loads the incorrect driver for this card.

I use the lspci command to display the details about my hardware. It will display all of your PCI connected hardware. I edited the output to show only the relevant information.  The important information here for  matching your hardware with mine is this indentifier [14e4:4312].

$ sudo lspci -v

The Solution

I am  going to install the correct driver for this wireless card. Then I will remove the “incorrect” driver (bcmwl) which Ubuntu installed by default.

$ sudo apt-get update
$ sudo apt-get install firmware-b43-installer
$ sudo apt-get remove bcmwl-kernel-source
$ sudo reboot

Hopefully you found this useful.

If you have this same type of wireless chip in your laptop, these instructions might also work for you.

Ubuntu 10.04 and Broadcom BCM43xx wireless

After installing Lucid Lynx Ubuntu 10.04 on my laptop, I had no wireless.  The wireless worked find under the previous two versions of Ubuntu.  The solution is to install the Broadcom 802.11 Linux STA wireless driver source.

$ sudo apt-get install bcmwl-kernel-source

$ sudo reboot

After rebooting, wireless works.

Updated: BTW my laptop is an HP Compaq nx6325.

Here are the vendor and device codes for my wireless.

$ sudo lspci -nn
