Broadcom BCM4311 on Natty 11.04

The Broadcom BCM4311 is a PCIe wireless device widely available in laptops sold by many manufacturers.

  • In the terminal the following command will provide the pci:id (pci number)

lspci -nn | grep 0280

ID Broadcom Corporation BCM4311 802.11b/g WLAN [14e4:4311] (rev 01)

These instructions are written for Ubuntu 11.04.

This card works with the driver b43 and ssb. Proprietary firmware is required which is not provided by default in Ubuntu installations. Install it with:

sudo apt-get install b43-fwcutter firmware-b43-installer

Reboot and the wireless should be working.

CAUTION: This pci.id is also claimed by the Broadcom STA driver provided by bcmwl-kernel-source. Installation blacklists b43 and ssb. The driver bcmwl-kernel-source driver wl doesn't work well and b43 and ssb are preferred. To remove the incorrect driver and blacklist, do:

sudo apt-get remove --purge bcmwl-kernel-source
sudo rm /etc/modprobe.d/blacklist-bcm43.conf

Some users have noted that the information above needs to be adjusted on Ubuntu 11.10, in which case replace the last line of code with:

sudo rm /etc/modprobe.d/broadcom-sta-common.conf
