I have opposite problem. My hub and V6 box are connected via ethernet cable supplied by VM and work fine. My LG smart TV apps eg iPlayer and Netflix cannot see the WiFi.
Can you connect your TV to the Hub by ethernet cable (lie the V6 is), if so, do so.

thanks for all the feedback, but in my view, Roger was the answer which correctly identified my point. Ethernet is advised as the connection to use, wifi is fallback. If the box/port is faulty, as a rental, we should get a replacement.
