I keep receiving bans from multiplayer because when I finish a game in arena the game says lost connection and can not receive data. This is a joke I’m finishing games and still being banned my current ban is 8 hours. How can I stop this from happening ?
You can get more help if you put this here 
But, if you keep getting disconnected and banned, maybe you should take a break for awhile so as to not rack up a ton of DNFs. You could also check to make sure everything is good to go on your end.
Like FatSkinnyman said, theres a sticky in the support forum. Im sure they would appreciate your input
