xbox series x - warzone and COD multiplayer lag spikes (LAN cable)

Im having the same issue, my internet is fine and everything else works fine in the house apart from my series x, using a ethernet cable over wireless makes no difference for me and I've tried all of what you mentioned, all the tests say my speed and ping are ok, but when i go to play warzone or fifa it spikes

Funny how I haven't had this issue on my xbox one x ever but when I go on my xbox series S then it just starts having the lag spike issues with my captures.

My Xbox series s i think it's getting heat and its lagging some times on forza for a few seconds and its lagging on nfs heat but i can press xbox button and get out from the game and it was lagging on apex mabye for 5 second but in cod warzone i don't think its lagging ( wierd connection)

I use Xbox series X.

I found on the internet cases similar to mine with the following games: AC Valhalla, Bonderlands 3, Cod Warzone.

I want to know if it is necessary to request a console change

have you tried a cable? your online experience (lag and lag spikes) and download speeds would be far better as well as being straightforward to connect
