I have removed the 1,3,4 and 6 wires from all the wall sockets. Which has helped slightly increase my sync rate.

When the phone line enters the house it goes in to this thing. ^^
Then it goes on to the master socket which has the ring capacitor.
I am sure this isn't helping anything, considering it looks like shit and is extremely old, as old as the house infact. I take it I can't remove it because of BT ruling etc.
