Public bug reported:
First of all, my wifi is working great most of the time, at least as
long as I don't use other network connections (rj45) and as long as I do
not suspend/resume and as long as I don't touch my hardware rfkill-
switch.
But, as it turns out, from time to time network manager
- can't see my wifi SSID any more ("********net" in the screen shot is some
other random wifi in the neighborhood).
- can't see any SSID in the neighborhood except one
Result: I can't reconnect to my wifi
Suggested Fix: network-manager should not loose the connection in the
first place or at least rescan the wifi neighborhood and reconnect to my
wifi.
Additional information: The configuration of my wifi is not lost. As
soon as a scan is performed, network-manager finds it and connects to
it. To initiate such a scan, I'm using this
Workaround:
sudo service network-manager restart
After that, network-manager performs a new scan, all SSIDs which are
available are found again and network-manager connects me to my wifi
automatically.
