Can you check in NetworkManager's log if it has crashed? The only reason I known for crashing in line solidcontrolfuture/libs/solid/control/ifaces/networkinterface.h:166 is it the NM backend is not working anymore and that only happens if NM has crashed.

Yes, it has crashed. It is connected with the wireless device, Atheros AR9485.
