Recently, Whenever I try to connect to the wifi, I click on the network and I get a warning saying "connection activation failed: connection could not be found". I even reinstalled Ubuntu and i still get this warning.
To try and check where your wifi issues may be, troubleshooting using these commands in a terminal (
T) can be handy:
- Check status of connectivity:
nmcli networking connectivity
- Check that wifi is properly activated:
nmcli radio wifi off ; nmcli radio wifi on
- See wifi access-points:
nmcli device wifi rescan ; nmcli device wifi list
- Try to connect to wifi:
nmcli device wifi connect "$WIFI_AP" password "$WIFI_PW"
Each of these should give you a hint as to why they fail , if they do.
