Our wifi password at work recently changed. I edited the old connection to have to new password by
$ nmcli connection edit "Internet" $ set wifi-sec.psk <password> $ save persistent $ activate
Everything was fine for about five minutes. but after that the connection went down. I can re start it but it continues to go down every 1-5 minutes or so (I had to restart wifi four times while typing this question). I sometimes get an error message when trying to restart the connection but even when the error occurs the connection will successfully restart.
$ nmcli connection up "Internet" Passwords or encryption keys are required to access the wireless network 'Internet'. Warning: password for '802-11-wireless-security.psk' not given in 'passwd-file' and nmcli cannot ask without '--ask' option. Error: Connection activation failed.
I've tried resetting the password for the connection again, and removing and recreating the connection all with the same results.
Is this an nmcli issue or a driver issue or something else?
