I have 3 virgin media entry points in my house 1 for old hub and 2 more for TVs,
Can I put my new hub onto a TV entry point
Yep they are all the same.
But the power levels might be different at each outlet so if you get any disconnections try and use a different socket - it'll be quicker than trying to arrange an engineer.
