[Bug 1438003] Re: (1) Creating object for path '/org/freedesktop/NetworkManager/ActiveConnection/0' failed in libnm-glib.

 

I have the same problem that Krupier (krupier123) has: connection dies
unexpectedly, and I am unable to reconnect using the Network Manager.
Restarting through `service network-manager restart` brings the system
down on its knees, until I stop the service.

However, I found a workaround: when I suspend my laptop and wake it up
again, the connection is up again.
