Good afternoon Joan, the YouView box should not be plugged into the telephone socket.
It needs to be plugged into your broad band router Ethernet port.
Since the router is in the other room the best way to overcome this is by purchasing what is known as a powerline adapter, this allows you to plug the ethernet cable into a box, which then sends the signal to another box which plugs into your router. These devices can be purchased from here.
There is also a short instruction guide on how to use them which can be found here which may be helpful.
Should you need any further assistance please let me know.
Hi Joan, I just wondered if you need any further assistance, and would appreciate if you could rate the service received to date.
