moved??? For instance my master socket is down stairs which is far-away from my PC and router(plugged in an BT extention) in the cabinet upstairs.Master socket is old type - not ADSL filtered socket and obviously needs replacing.Well when I change it I would have two options - eitgher to plug the router directly in the socket with 30 foot long extention cabel( not preferable very inconvenient ), or plug the BT extention in the new ADSL socket.Would that make any difference??
