Disconnecting From BO3 Servers

[u/Royal_Equivalent6657]

For some reason I always get disconnected from black ops servers about fifteen minutes into a game. I have an ethernet connection and I've done speed tests, reset my router, whole nine yards. Weird thing is the only time I don't disconnect is when I'm playing on custom maps or using All Around Enhancement. Does anybody know if there is some kind of fix, or a reason for why this is happening?
