6GHz not working

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?

@JustinV the AP was replaced, but due to 31.1.5 being released, the new one got trashed, a second RMA and going back to 31.1.4 fixed it, it is working as expected now, must just have been a faulty AP 😎

I have plenty of 6GHz on my 9166, running 31.1.3.

Sorry, WPA3 only. Not transition mode.

What have you set as the Flex Radio Selection on the RF profile? I think I had to change it from 5 to 6 GHz.

All set to 6GHz, but I'm using passphrase that might be the issue.  802.1x seems to consistently be reported as okay, but I haven't tried it yet.

The Emoji SSID, is in WPA3 Transition, but doesn't show up when in 6 Ghz only. If I enable it on 5 GHz aswell is shows up.

 

Disabinling  5 GHz again, but changing it to WPA3 only, makes it show up on 6GHz only.

Works as expected:

But I also always have a 5 GHz SSID. IMO, it's too early to rely on PSCs only.

 

All Security types work as expected:

And I am on v30.7

Glad to know it should work with the settings I've got, hopefully support will find something!

One other odd thing is the 9166 sees it's own 6GHz broadcast as a neighbour:

As you can see 'Hallway AP' sees 'Hallway AP' as a neighbour.  This only happens on the 6GHz band.  Another point of note is that all APs on all channels show channel 0...

Thanks @JustinV , at the moment the case is still sitting waiting for them to contact me, the case ID is 12164397 if you want/can take a look. 😊

@cmr Those Channel 0 specs look like they're coming from the AP Neighbors page.
Just a quick heads-up that the Cisco Meraki AP Neighbors feature is currently in Early Access an is still being fine-tuned, so you might encounter a few bugs here and there. 

I've seen the same bug and have added Feedback as well. Thanks for reporting it cmr!

In the meantime, correlate between there and the Wireless > RF Spectrum page and/or the AP's page and Radio Settings displayed.

Between these, you've got that 6GHz channel and width information.

So far I have only had the problem when creating a PSK/SAE transition mode SSID, 6Ghz does not show on those.

Dot1x transition mode SSIDs and "pure" WPA3 SSIDs it works as expected.

When I get back this weekend I can retry , re-verify because I also need to put up another CW91xx in my lab 🙂
