I am having the same problem.
Mobo: Gigabyte X570S AORUS ELITE AX (rev. 1.1)
WiFi Adapter: RZ608 Wi-Fi 6E 80mhz (driver: 3.2.0.0192)
WiFi 6 @ 5ghz works. As does WiFi 5 @ 2.4 and 5ghz.
WiFi 6E @ 6ghz does not work. It doesn't even show 6ghz as an option in advanced settings under preferred bands
The RZ608 is very common across AMD motherboards and I was wondering if anyone had had any luck getting WiFi 6e (6GHZ) working?
Thanks
