Hi all.This is my first post here.
After today's upgrade from Backbox 4.4 to 4.5 with the new kernel,my BCM43227 wireless card stopped working.
I've made some reasearch and found this :
The Broadcom wireless driver from stable Ubuntu repositories does not support kernel 4.1 yet.
The way i have managed to fix this was to install patched package from PPA :
sudo apt-get remove bcmwl-kernel-source
sudo add-apt-repository ppa:longsleep/bcmwl
sudo apt-get update
sudo apt-get install bcmwl-kernel-source
I hope this helps someone with the same problem.
