sudo rfkill list all returns nothing.

Any help would be greatly appreciated.


Open terminal, plug an ethernet cable to get internet and run the following commands:

sudo apt-get install bcmwl-kernel-source
sudo modprobe -r wl
sudo modprobe wl

Wait 5-6 seconds and check if you pick up wireless networks.

Edit: Got it to work, just like you said. Had forgotten to uncheck something in Synaptic package manager from a previous attempt.

The help is much appreciated, thanks for the quick response, madvinegar.

Glad I helped. I will mark the topic as solved.
