Wi-Fi disabled by hardware Switch – How to fix?

For some reasons, I still use Ubuntu 16.04 LTS. I’m not attached to it, and neither I get myself into the arguments related to Windows vs Linux.

To be honest, I don’t have much time to try the new OS(s). I miss the old days when I could test multiple distros of Linux in a day and still feel the hunger of trying more. Those were the days.

Anyway, I chose Ubuntu as my distro for the sake of stability.
