It looks like after enabling auto channel selection and background scanning the 2.4Ghz channels and some 5Ghz channels on our AP's have disabled. I can't find how to switch them back on for the life of me. I have created seperate WLAN groups to steer devices between 2.4 and 5 ghz via SSID but ideally need the 2.4ghz available for IoT and guest. Does anyone have any idea?
TIA
