I have a handful of RPi 4s that are connected to WiFi. I can tell using nmcli device wifi that the Pis are connected to a 5 GHz channel. Unfortunately I don’t have control over the access point so I can’t separate the channels to 2.4 GHz and 5 GHz. Is there a mechanism to restrict the Pi to joining only 2.4 GHz channels or a specified list of channels?
