Hi All,
As many of you maybe aware, some customers have reported that since installing the latest update of Sky Q firmware (Q120), they have had issues with their BT Whole Home Wifi when a Sky Q/Sky Q Mini box is connected to the BT Whole Home Wifi via Ethernet.
We are currently in the process of identifying why this latest update is causing the issue and a joint investigation with Sky is in progress. In the meantime, you can connect your Sky Q boxes via wifi in order to eliminate this issue:-
