Cheers peeps. I put the cables back to where they was before I started and it was still the same, I am going back over there after lunch, but I just had a thought, their son download on demand stuff from the Sky box, so I wonder if the box is downloading stuff and that is why the net is slow. I will check that this afternoon, if so then that is my problem.
The reason why I have been sorting the cables out is because the connection sky put in top connect their boxes to the phone line is now failing, in that it is broken, so the idea is to take it out all together, Sky do not seems to bother with it these days anyway. I will disconnect it for a few weeks and see if sky contact them, if not then the cables can be got rid of.
