I didn't look at 'Google reports', I looked at the specification on the Asus website.
Ah - the technical fine print got me - seems odd they would release a WiFi6 version now, but doesn't work on BT G.fast? Do you know if firmware updates can solve this, or do I need to send back to Amazon? If a non-starter that seems like an own-goal such that it cannot combine with other Asus AIMesh devices and then need a non-Asus modem/router?
As has been mentioned in another recent post the market for G.Fast devices is quite small and will not be increasing so not much in it for the device manufacturers.
I think there are only 2 modem/routers suitable - the Asus DSL-AC88U and a very recent TP-Link one - and that's it.
