RF Spectrum - Overlapping, Interfering channel

[wacarrol]

Frustrated. Wifi6e 6GHz channels always show an overlapping, interfering channel whether it's 5GHz, 6GHz. Does this affect packet loss? I suspect it may have something to do with WPA3 but why would the RF Spectrum show a 'red' interfering neighbor?

Are all APs using the same RF profile or does each AP have their own RF profile?

[wacarrol]

One indoor profile (3 APs), 1 outdoor profile (1 AP).

Can you show your RF profile configuration please?

One piece of advice: do not use a channel width of 160 MHz, as this will considerably reduce the number of available channels and you will have the same problem as in 2.4GHz. Instead, use a maximum width of 40MHz.

I'm 100% with @alessandrodematos .

It gets worse because the amount of 6Ghz spectrum available depends on your regulatory region. For example, in my region, the bit of the 6Ghz band you can use is the same size as the 5Ghz band.

Of the top of my head, 160MHz would eat half the available band.

Thanks. Will give that a try.

Do you by any chance have meshing enabled, on the Network Wide Settings page?

Meshing will make all your APs broadcast a hidden SSID used for the Meraki Mesh feature.

That was it! Not sure it caused any issues but it was annoying to look at. Thanks, I've turned off meshing and the 'overlapping' channels (SSIDs) went away.

Thanks everyone for the suggestions
