Issues with XR450 and Destiny 2

I have the Nighthawk XR 450 firmware V2.3.2.40 and yes I have done the reset with all ethernet cords disconected.

I am having serious issues with destiny 2 for PC, I can play for about 15 minutes till I get disconnected from the router, have to unplug ethernet cord and replug to get connected back to the router. I have qos set for the specific ports, geofilter is correctly setup and not on strict mode and set to ps4. I have a netgear CM600 modem and I have verified that it is not causing the issue, I have zero issues if i plug straight to the modem but I need a router for other pc's and devices in the house.

My logs have alot of this

when the issue seems to happen I don't know if the 2 are related. Hope for some help because this is the only game I play and currently cannot play due to how the router is not performing. I'm pretty much at about the point of going and buying something else from elsewhere to find something that can work with the 1 game I play.
