Looking at the speeds you are getting I'm assuming you are on a fibre broadband connection. What vDSL filters are you using as your NTE5 master clearly hasn't got the faceplate vDSL filter which would give you some other options and possibly increase your speedThanks Gilko,
My current speed data is below. btw, The speeds are about the same whether I plug the router in at point "A" in the bedroom or point "B" in the living room.
Download speed: 53.96 Mbps
