I'm breaking this out as it has appeared as a comment in a number of other posts.
I don't seem to be able to get any SSIDs to broadcast on the 6GHz band on 30.6, 30.7, 31.1.3 and 31.1.4
I have a CW9166I and two CW9163Es, I'm not expecting to see it on the Es as that isn't legal in the UK, but the I thinks that it is broadcasting, but Samsung, Apple and Google devices that all support 6e don't see anything.
I have created a dedicated SSID with WPA3-SAE to test with and it is invisible...
I've logged a ticket, but wondered if anyone else had got the above config working?
