Don't be shocked by the Asus in the title. Although I manage a Ubiquiti Unifi/Protect/Aircontrol and UNMS network, at home in a tiny apartment things are on a budget. I don't need a unifi setup for a 60 m² apartment where and a internet connection off 100/20Mbps. But that doesn't mean we can try and optimise our network settings. In this case for a basic Asus RT-AC58U home Wifi Router.
Since you are reading this I'm assuming you you know how to login to your router. Now your ISP connection speeds and understand some slight I.T. jargon.
Configuring QoS and prioritise Playstation/Xbox
I cannot guarantee that based on your model router or firmware that these instructions will stay complete or be accurate. But these instructions should point you in the right direction:
* For Xbox connected via Wireless there is an checkbox on the "Wireless" page for both 2.4Ghz and 5Ghz to optimise for Xbox. No idea what is does but you can try and enabled that too.
Optional router tweak
As a engineer I firmly believe in the power off turning something off and on again. If you haven't watched the TV show the "The IT crowd" I recommend you do so. Asus routers have the option to to a scheduled automatic reboot. This is something I enable as a preventive measure in case there is a bug in the firmware like a memory leak or something else. If it in theory can improve reliability why not enable it?
