[QUOTE=TURIN;11001843]Thanks for the replies.
This is the root of the problem. He's had about five BT 'Youview' boxes that keep failing. We think its because he uses those internet adapter plugs to send the broadband over the house electrical circuits. Until I can get in there and route an ethernet cable half way around the house to the BT Box, I thought it would be a quick temporary fix to use the smart TV App.
Been using BT Youview boxes for years connected to homeplugs, the box just sees it as an ethernet cable. That said the occasional electrical spike might affect the pairing but that can be fixed by switching them both off then switching the master back on before the slave.
