The V6 Box requires two connections ...
A white co-ax cable the same as the one going into the back of the Hub.
An internet connection, this can be by an ethernet cable from the Hub or a Wi-Fi connection to the Hub.
You will need an engineer to put the co-ax cable in for you.
Is there a brown box on the outside wall of the room where you want to site the V6 box ?
You can contact VM to report the problem using ...

150 from Virgin landline.
0345 454 1111 from any other UK phone.
The best time to call is weekdays 08:00 to get a UK agent, anything after 10:00 you must realise that you are quite likely to get through to an offshore agent that doesn't speak English as a first language.
Or you can wait on here for one of the VM Staff to pick up the thread but this may take a few days.
