Hello Anji1
Sorry to hear of the problems with your set top box, we understand the concern this can cause and appreciate you raising this via the forums.
From looking at the account this is a V6 box so unfortunately as japitts explained in his post, doesn't have the internal connection option. From looking at the box on your account it is currently showing as offline. Can you ensure the box is switched on and follow these steps via the menu
TiVo/V6 setting help - Home, help and settings, Settings, Network, Connect to the Virgin Media service now
Please let us know how this goes.
Rob
