Ubuntu – Wireless is disabled by hardware switch

This commonly occurs right after an upgrade/update to the operating system.

1. First thing is first – your laptop will probably have a Wireless On & Off feature which is either on the side of the laptop chassis or front usually in the form of a button or switch. If it’s off, turn it on!
2. If the wireless is turned on and you are still getting an issue open a Terminal and type: sudo rfkill unblock wifi
3. Press Enter
4. You should now be able to access the wireless.

If neither of the above work – then the problem most likely is you’re wireless on & off switch and it might need to be rewired to be permanently on.
