@PaulaN9 most devices although they only use the 2.4GHz band can be connected to a dualband WiFi SSID. However if your ovens wont connect and you have a white Sky hub go into the hub's advanced settings in the Product Settings section of the My Sky app and click the WiFi Disable link then tirn off the 5GHz band once the hub has made thst change using your phone connect the ovens. Once connected do the same process but this time turn on the 5GHz band and yhe hubs should stay connected.
If you have a blsck hub follow these instructions Split Sky WiFi bands
