i recently buy the xr 500 nighthawk my question is does the qos do anything if u have only 1 device

If you are doing multiple things on that one device such as streaming and gaming then yes it will help. If you're just gaming then you're probably not experiencing local congestion, in which case it will not be as useful.

I see thanks for the reply so i disable it completely? Because most of the time i just gaming

[Netduma-Fraser]

That's up to you, keep in mind devices (even if a phone is connected) can do background updates which would cause you to lag. If it's truly just the console online then you could disable but you probably have enough bandwidth either way so not necessarily needed.
