I had a FTTC install last week on a brand new master socket.
I am aout 100m from the wiring cabinet and the DSLAM (are they still called that?) is right next to it. The engineer found a fault with the port I was supposed to get - it tested slow at the cab - and arranged for a move. He waited there for 30 minutes and came back. I wandered down to see what was taking so long - that's why I know what happened.
Anyway, given that I am 100m from the cab I figured I should be getting excellent sync speed.
Speedtests indicate about ~50Mbps down and ~12Mbps up, both from BT and speedtest. The estimated speed at provisioning time was 68.1Mbps which is more realistic.
I've tried a number of routers and a direct connection - no difference.
I finally unlocked the modem and can see the following. Not sure where to look, but I'm sure there's still a fault somewhere, or does this look about right?
