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

30:00.0 Network controller [0280]: Broadcom Corporation BCM4312 802.11a/b/g [14e4:4312] (rev 01)

  1. Odd that you would have to install the source code for the driver to work, but I will certainly give this a shot as I just finished installing 10.04 on my Dell Inspiron 1720, which uses a BCM43xx-based wireless card.

  2. You are actually installing a different driver, when you install bcmwl. After the install you can see that a new blacklist file was auto-created:/etc/modprobe.d/blacklist-bcm43.conf, whereby the previous driver is now blacklisted to prevent it from loading.

    Good luck.

    • Check your blacklist statements in /etc/modprobe.d and confirm that you are not blacklisting one of the b43 or STA drivers when you don’t intend to be. Here is a link to the Broadcom page for their linux STA drive, in case you want to try compiling it yourself, or perhaps you’ll see something in the README file that helps (http://www.broadcom.com/support/802.11/linux_sta.php)

      If you are not able to use the b43 kernel driver or the precompiled STA driver explained in the post. You can try using ndiswrapper and the windows driver for your card.

      The Ubuntu page for ndiswrapper needs updating (https://help.ubuntu.com/community/WifiDocs/Driver/Ndiswrapper). The steps for Lucid are essentially the same.

      If you decide to go this route, be sure to disable the b43 and STA driver before using ndiswrapper. Add the following two lines to /etc/modprobe.d/blacklist.conf and then reboot.

      blacklist b43
      blacklist ssb
