I lose a warzone game by 100, due to extreme lag, quit a second warzone game because of the same lag, finally play arena and the same lag, so i figure its my internet thats bad, i i check on my bro, whos playing halo 5 in another room, NO LAG AT ALL, surprised i head back to my game and i get the 9:54 ban for the first time… wow
Dedicated servers mean that theres no black screen when a player quits or joins, if you’ve played reach you know what im talking about :p. It seems that it could be your connection as your bro was eating all your bandwith leaving you little speed. Maybe port forward your own xbox so that device gets the priority over others. Or use a wired connection.
