3) What you expected to happen
4) What happened instead
I have just installed Ubuntu on my laptop with a BCM43142 card. I have
install the recommended driver for this card, the bcmwl-kernel-source,
however it is not working properly. It detects the different wifi
networks available but the signal is really low. With my other
devices, phone, tablet and in windows 8.1 I don't have this issue, and
I can easily connect to them.
Because signal is so low, it is constantly connecting and
disconnecting.
