@Streaming1 doubt Sky will let you revert. However there is a method of attaching devices which wont connect to the standard dualband SSID which is to temporarily turn off the 5GHz band by logging into the My Sky app finding the controls for tge Sky Max hub go into thecadvanced section. Oncecturned off connect your IOT devices and tge re-enable the 5GHz band and your devices should stay connected.
