Hello all, a bit of a strange question.
I have Virgin and it works fine. The thing is though I haven't got one of those brown box things outside my house like neighbours have.
What I have found in my cellar though is a white box with NTL on it, with 2 wires coming out of it connected by what looks like TV aerial connectors. One of these wires then goes through the stairs and into my living room and then into the Tivo Box.
At the side of this box there another connector, this one is metal with 2 wires with the same connectors.
What I'm wondering is, if there are no visible wires coming into my house, how is the service getting there?
I've checked next doors brown box and there are no wires leading to my property from it.
I just don't want anything illegal to be going on, although I get billed and have an account number.
Any thoughts on this? TIA, WWAS x
