The router normally sits in my office and is on the end of good quality telephone extension wire that weaves it's way under floor board and up walls, and is probably 15 metres in length by the time it reaches my office
When the router is plugged in to this extension, it syncs to the exchange at about 19750 downstream and about 828 upstream
When I plug it in to the master socket (disconnecting all extensions), the router syncs at about 17000 downstream and 1000 upstream
When I return everything back to it's original position in the office, the router syncs back at 19750 downstream and 828 upstream
I have tried this several times and when moving the router to the master socket the downstream sync drops and the upstream sync increases
The thing that is puzzling me is that when plugged in to the master socket, I would expect the best up and down sync, but the downstream decreases but the upstream increases
Can any one explain this behaviour to me?
