Over the last couple of days, we have started running into some issues with our M1 Macbook Airs not connecting to AP230s that have the 2.4GHz channels turned off. We have APs in every classroom and we turn off 2.4GHz in most rooms so that there is less co-channel interference. The Macbook Airs are getting a self-assigned IP address when they connect to the 5GHz in the rooms with the 2.4GHz turned off. They connect just fine to the 2.4GHz in the rooms that have the 2.4GHz turned on and they also connect just fine to the 5GHz when I take the computer to a room with an AP650. Is this happening to anyone else or does anyone know what could be causing this?
