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?

Best Answer

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.
