- Determine the current state of the radio transmitters using rfkill. You’ll be able to see immediately If any of your devices are soft blocked.
$ sudo rfkill list all
- Unblock radio transmitters as needed. In my case, something was turning the Wi-Fi off. I just had to turn this on using the below command:
$ rfkill unblock wifi
Note: In a few laptops the Wi-Fi key is also mapped to the Bluetooth function, so to activate or deactivate you’ll just have to tap a few times to disable or enable wifi and/or bluetooth.
