HI,

All of my devices are unable to see my 5GHz-1 channel.  Both the 5GHz-1 and 5GHz-2 have the same settings.

WPA2-PSK[AES]

Transmit power - High

Channel width - 20/40/80

Channel - Auto

802.11a/n/ac mixed

But if I turn off 5GHz-2 channel, all of my devices (iphones iOS 18.1.1,  macbook OSX 14.7) are unable to see the 5GHz-1 channel.

Also my Sonos ERA 300 can't see either 5GHz channel.

I would appreciate any advice.

Cheers
