Losing connection during any online session

Every time I play the game i dont last for more than 10-15 minutes before getting disconnected, and when i try to rejoin the same online session it tells me that the session no longer exists or it says error can join the session for a reason that I cant remember and when i am in the online session i have to predict where people are going to be because of the poor connection I have apparently because every 2-5 seconds the player has a red x next to there name
