I know AVM (i.e. FritzBox) and Devolo make WiFi devices, but both don’t offer access points. I guess you could use a FritzBox, but their design don’t make them suitable to be boltet to the wall of a living room.
I found Mikrotik that are a bit difficult to configure and LevelOne.
Are there any other options?
WiFi 6 works fine on OpenWRT, you can check if your specific hardware would be supported here: https://openwrt.org/toh/views/toh_available_16128_ax-wifi
