Comment 35 for bug 1722256

I had not seen this issue for a long time. But now I see it again.
Note that I am using Fedora 30 instead of Ubuntu, but this could very well be a non-distribution dependent issue, therefore I'm reporting here instead of opening a new issue in another bug tracker.

The question mark appeared after I had been fiddling with the wireless connection settings in an attempt to connect to a Ziggo Wifispot via WPA2-enterprise (in the end I did not manage to connect).

After that I connected to another wifi (that is now fully functional), I see the question mark.

Some output from nmcli monitor:
