If you need the same output when it doesn't work, I need to reboot
Comment 3 Jan Grulich 2016-04-27 12:01:17 UTC
Yes, I need to see the output when the applet is empty. Anyway, this looks like an issue in NetworkManager. If NM doesn't show any available wireless connection before it gets restarted, then also the applet won't show any wireless network or connection.

Ok I reboot and here is the ouput before and after sytemctl :

Ok, that's a bug in NetworkManager. As I said, we display what NetworkManager see and if NM doesn't list any wireless network then we have nothing to display too.

Report your problem to NetworkManager bugzilla.
