I am posting this thread after trying all the solutions provided in the forums but it does not work for me.
These are the step that I have taken:
1- installed Ubuntu 18.04 LTS (with all the updates)
2- wifi not working, so I run sudo apt purge bcmwl-kernel-source ,reboot, then run sudo apt-get install bcmwl-kernel-source
The Wifi started working, but when I reboot the computer it stops working again.
I added these to /etc/modprobe.d/blacklist.conf but still no luck:
what exactly am I doing wrong?
