Packet Loss resulting in disconnects

Everytime I attempt to play COD Vanguard I get packet loss to the point of a disconnect. I will ping fine for awhile and everything will run smoothly, then out of the blue a packet loss and disconnect. I have forwarded ports. I have updated all software and devices. The only game it seems to happen on is this one. I have tried resetting the Gateway and the problem always returns.  I am wired as well so not a WiFi problem.
