Could you please look again in
https://bugzilla.redhat.com/show_bug.cgi?id=797709 , all commits/patches
mentioned in this bugreport unfortunaly doesn't fix the problem and connection
still hangs, I've tried reload all wifi related modules but wifi signal didn't
appears, it works only after reboot only a few hours and then again randomly
hangs. Also tried drivers from realtek site but result the same.
