At some random moments my network connection fails (limited acces only) and if I try to fix it network connections just crashes and won't reopen. Also I've noticed if this problem occurs(limited acces) I cannot start games or shut down windows. If I start a game then it will just immidiately crash and say ... has stopped working. And if I try to shut down it will stay on the windows is shutting down screen(the activity circle still rotates).
