Use a Raspberry Pi 4 for your router and use other ’routers’ as dumb access points. It is the best setup I’ve had. Its CPU is easily fast enough to handle the advanced software flow control that allows really good QoS. My ping times don’t meaningfully change whether my connection is loaded or not. Then you can upgrade the wireless without having to replace your router which does all sorts of non Wi-Fi functions. It does require using an external USB3 gigabit Ethernet adapter.
