Can't Stay In A Game.

Nearly every game this bull**bleep** happens I'll be up multiple scores and lag out. It's not my internet. I'm on 6GHz with full bars, no lag, only one on the internet because we have a router for my Xbox and router for everything else, and I'm on series X. Getting tired of losing 5-0 seasons and when I don't get lagged out in the regular season I get lagged out in the Wildcard or Conference Championship. I'm genuinely getting to the point where I don't wanna play because EA screws me over with dog **bleep** animations and anything it can to give my opponent an edge. Then if they are losing I lag out. It only happens when I'm winning and that goes double if it's by multiple scores. It has happened upwards of 40 times and it's getting ridiculous. Fix your **bleep**ing servers.
