@BrendanDR all but the Sky hubs which are 10 years old offer dualband wifi both 2.4GHz and 5GHz. Some devices find it difficult to connectvto a dualband SSID. On the black hubs follow these steps to splitvthec2 bands https://helpforum.sky.com/t5/Broadband-Talk/How-to-separate-WiFi-bands/ba-p/3530610
On the newer white hubs you cannot splitvthe bands therefore you need to usecthe hubsxsettings in the MySky app to turn off the 5GHz band temporarily connect the devices affected then turn the 5GHz band back on.
