I dunno how much your router settings have been changed... But when I was at visiting my dad for a weekend I was literally unable to play due to his router settings. He had some ports blocked, had some throttling on the bandwidth, etc. Didn't effect most things, but it turned out to totally screw the League connection.
Maybe try resetting your router to factory defaults(And re-updating the firmware). It might not make a difference, it might already be at defaults, etc.. Best suggestion I have though :)
Thanks a lot! I hope it works! I'll get back to you if I see any difference.
