A friend of mine has been having issues with broadband not syncing with the exchange.
I went over to have a look and basically the master socket is a tiny white box, and normal household telephone cable comes out of this box, and into what looks like a NTE5 type master box - basically the two blue wires are wired in to point A and Point B. (Probably originally wired by B.T. many years ago!)
I am guessing there will need to be some re-cabling work.
Sometimes it syncs at 4mb put will eventually drop down to 800k and sometimes keeps recycling the connection, there is also crackling on the line.
The problem she is having is making the B.T. foreign call centre understand the NTE5 type box is NOT the real master socket! So the problem is still on going. Does anyone know a better way to speaking/contacting B.T. so this issue can be resolved.
