How to Install Broadcom / STA Wireless card (BCM43XX)
Can’t connect to any wireless connection after updating

Using wireless successfully on 2 DELL VOSTRO 3500 laptops.

Both have failed - second one after update today. Sending me here.

Instead of trying various installs and un-installs - can I simply wait for another 1 month? Will the new kernel solve this issue?

  • @hhlp No, that's not OP's issue - wireless was working.

  • What makes you think it's a kernel issue. I think it probably has something to do with the bcmwl-kernel-source upgrade in Precise. Feb 3, 2013 at 13:15

The recent problem with BCM4313 cards seems to be related to an upgraded version of the bcmwl-kernel-source package. As a workaround, I suggest downgrading it to the previous version, by using the following steps.

  • Run sudo apt-get remove bcmwl-kernel-source to remove the package.

  • Install the older version

    sudo apt-get install bcmwl-kernel-source=

Manual deb downloads are available from here: 32bit, 64bit. Install the downloaded file by double clicking.

  • Lock the packages version to prevent updates.

    gksu gedit /etc/apt/preferences.d/bcmwl-kernel-source

and paste in the pollowing

Package: bcmwl-kernel-source
Pin: version*
Pin-Priority: 1001

PS: The workaround has been adapted from here. Unfortunately, I've no way of testing it, so please, let me know if it works, ... or not.

  • I think this (good) answer belongs in the duplicate question.

  • Thank you very much. I'm using official 3.5.x Kernels for Precise and this finally fixed my WiFi issues with random routers I had. It cannot be true that a LTS has this major issue and that I (!) had to downgrade (not even upgrade) WiFi drivers. Jul 8, 2013 at 10:15
  • If you are using 3.5.x Kernels in Ubuntu 12.04 you should follow this guide from @mikewhatever but make sure you are using version and this .deb package: packages.ubuntu.com/quantal/bcmwl-kernel-source Version will break your bluetooth (my headset was stuttering). Thanks again! Jul 10, 2013 at 10:16

You don't need to wait. You can install the new kernel now (package has been available for a few month) and see if that fixes your issue.
