My Youview box is connected to the ethernet via powerline adapters. I bought a Now TV box for the sky internet channels only and tried connecting it the same way as the Youview box using the same powerline adapter with Youview already connected.
Well, the router just didn't want to know about my new set-up so I disconnected the Now TV box and all was well again.
Basically what am I doing wrong and is it possible to achive my aim.
Its possibly the multicast packets which are destined to go to the YouView box, getting into the NowTV box.
If you disconnect the Ethernet lead to the YouView box, and just use the NowTV box, is the home hub happy?
You may have to used a smart or managed Ethernet switch, connected to just one port of the powerline adapter, and feed the YouView box and NowTV box from that switch.
That will ensure the multicast only goes to the YouView box.
