I have just moved into a house and I am having trouble locating which phone point is the master socket. The Broadband speed is terrible so I called SKY who told me to plug Router directly into master socket, i.e take off the face plate and find the direct line. They said they were getting fault on the line and hence slowed down the speed of broadband. They also stated it my responsibility if problem is with my network internally. Going mad as I can't prove anything at the moment. This is where I am struggling, all the plates are flat modern stainless steel with no indication as to which may be the BT line. I have done obvious thing and followed the line into house but it disappears. So I took off plate nearest to where it comes in, no joy. I have also taken off all plates in the house. I don't mind paying for someone to come and sort it out but not sure who I approach?
Is there a peice of kit that will determine where it is? I assume there must be master point?
Please help as driving me bonkers.
