Code:
sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree
this is what i did
installed 13.04
wireless did not work
installed non free firmware using ethernet cable
wireless worked
upgraded kernel to 3.9
wireless still works
so do i have a different br4311 chip, will i have a wireless problem?
do i have a wireless problem of which i am unaware?
