Recently taken delivery of new Smart Hub 2 and associated black disc. Initially everything seemed OK but we have noticed that all connections to the Disc in our family room are 2.4ghz - the other devices looking for 5ghz are connecting to the HUB with a poor signal. Despite several attempts we cannot find a way to get the devices located in the family room to connect to the Disc (also located in the family room) . Thinking of sending this equipment back to BT as I did not have the same problems with my old setup.
