I've had Xfinity for about 6 months now I have the performance 60 up 5 down and I was able to play online wired or wireless with no problem. About two weeks ago it all changed I have not been able to stay in a stable game I get in any game and I lag out in like 1 Min I've tried everything from Port forwarding to resetting my Xbox. When I test connection it says Nat is open or sometime it says double Nat or Toledo I've tried everything got any advice.
