Answer 1

I believe you have the incorrect driver. Please run:

lspci -nn

Is your Broadcom wireless device identifier 14e4:4318? If so, please do:

sudo apt-get remove --purge bcmwl-kernel-source
sudo apt-get install linux-firmware-nonfree

Reboot and tell us if it's working. If that is not your device identifier, post it here and we'll propose a solution.
