We have just moved into our house and only had VM connected for just over a week, have never been with them before so this is all new to us.
We have a brown box outside which has 3 cables inside. Only 1 of these is attached and goes from the box, along the wall and into our lounge box then straight into our router. The other 2 cables go up the outside of our house and into the wall into 2 wall boxes in the back bedrooms. Can these cables be plugged in and the boxes upstairs used at all?
