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?

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=5.100.82.38+bdcom-0ubuntu6
  

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 5.100.82.38+bdcom*
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.

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.
