I keep answering my own QU's... Apparently to be able to view the sport channels via the youview box I need to be 'hard wired' to the router. However I am perfectly able to stream netflix via my console using the powerline adapters etc..
I get the above error message, so I tried to connect to the router directly, made no difference.
I then connected my laptop by wire to the switch that connects to the powerline adapter - it was able to load bt sport 1 and 2 almsot instantly with decent image quality.
Does anyone else have this problem? I think its a little stupid for BT to provide powerline adapters, then tell me its not possible to use it with BT sport when actually they are easily fast enough to hold a solid connection and load large files.. I do this trying to stream content via netflix etc..
Im barely 3 metres away, but due to the locations of the TV and router, I do not want wires to be trailing around the TV room.
