Losing Connection every other game

I have a high Internet speed.
Open NAT.
60 download, 6 upload.
All my ports are forwarded as need be.

But I continually keep getting disconnected every night in just about every other game I play in Halo 5.

This just started happening to me right after the latest xbox live update. Before the update I rarely got disconnected.

Can anyone help me out here?
