After an update a few days ago, my wireless driver is not working anymore, unfortunately. I tried several things, but it all didn't work and now i dont have any clue what to do. maybe someone can help me.
Basic info: Ubuntu 14.04. Ethernet is working. When ethernet unplugged, no wifi connections show up. Before the update everything was working fine. I bought a wifi USB adaptor, however this also didnt work. (TP-Link T2U)
I run a scripted to provide some information (from here ): wireless info
I installed an additional driver (bcmwl-kernel-source ) as explained here. This did work till the update. Also followed this for the USB adaptor, but also didn't work. I also tried the live version of 16.04, but neither the USB adaptor nor the internal driver is working.
Can anyone help me and maybe tell what i could try? Thanks a lot!
EDIT:
Did the sudo modprobe wl code, outcome was:
modprobe: ERROR: could not insert 'wl': Required key not available
My secure boot is disabled. No clue what this means.
