Multiple SSIDs on 6GHz

[roo54]

I have a network built of CW9164 APs (MR 31.1.6). I would like to run a Corporate and a Guest SSID on both 5 and 6GHz. I thought I'd configured it to do so, but when I survey with Ekahau/Sidekick2, I can see only the Guest SSID on 6GHz. 5GHz is carrying them and other SSIDs. What am I doing wrong

@roo54 exactly. The 2.4 and 5 are fine, but 6 is optimistic!

I think I have, with all the help that's gone before, got the solution(this thread is worth reading, not for my contribution, but for the contribution of some big-hitters out there).

The issue is this: because there are so many 6GHz channels, they can't all be scanned. One of the ways of handling this is "Preferred Scanning Channels" (PSC), which limits the number of channels that a client has to scan (and so scanning time) to find a useable channel. However, another technique is "Reduced Neighbour Report" (RNR), that embeds the beacon of one SSID in another SSIDs beacon. It seems Ekahau only lists one beacon, but if you open the beacon packets up and look inside, there is the "missing" beacon, included elsewhere....and even if its a beacon for a 6GHz channel, you may find it in a 5GHz beacon....I *think* I've got it right, but shoot me down if not!

This „Problem“ will luckily not limit your clients. They all work with RNR and are not dependent on PSCs while scanning.
This is especially important for Europe as the typical channel width is 40 or even 20 and half or even 3/4 if the channels are not on PSCs.
