So I've sorted a Zgemma out for a chap at work all working fine at my place with his Ethernet home plugs or direct via cable. However on him plugging it in at his place with the same plugs/cable he's only getting FTA.
He has a BT home hub 4 where as mine is on Virgin.
I've looked into the smart setup and told him to disable it.
Any other things that could be the problem??
