I had a look at my Updates history in Ubuntu Software Centre for the last couple of weeks to see if I could spot any "likely culprits", and I see that on the 18th February the 'dkms' package got bumped from 2.2.0.3-1.1ubuntu5.14.04.9 to 2.2.0.3-1.1ubuntu5.14.04.10 and the 'shim- signed' package got bumped from 1.33.1~14.0.4.3+13-0ubuntu2 to 1.33.1~14.0.4.4+13-0ubuntu2
I found https://askubuntu.com/questions/138284/how-to-downgrade-a -package-via-apt-get and 'apt-cache policy dkms' tells me that only versions 2.2.0.3-1.1ubuntu5.14.04.10 , 2.2.0.3-1.1ubuntu5.14.04.5 and 2.2.0.3-1.1ubuntu5 are available (not 2.2.0.3-1.1ubuntu5.14.04.9), so I tried 'sudo aptitude install dkms=2.2.0.3-1.1ubuntu5.14.04.5` and got the following output: The following packages will be DOWNGRADED: dkms 0 packages upgraded, 0 newly installed, 1 downgraded, 0 to remove and 0 not upgraded.

I then rebooted, and Wifi still wasn't working, so I did 'sudo apt-get purge bcmwl-kernel-source && sudo apt-get install bcmwl-kernel-source' and the Wifi device re-appeared in my Connections menu but said "device not ready" so I did another reboot, and my Wifi is now working again! Hooray :-D So there's obviously some strange "interaction" between bcmwl-kernel- source, dkms and shim-signed ? I have no idea which package this bug should be filed against / moved to. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1818134 Title: modprobe: ERROR: could not insert 'wl': Package not installed ubuntu14.04.5LTS kernel 3.13.0-165-generic Status in bcmwl package in Ubuntu: Confirmed Bug description: when installing bcmwl-kernel-source to build wl.ko package version: 6.30.223.248+bdcom-0ubuntu0.2 Expected behavior: kernel module wl.ko loads.
