What makes you think you should be getting more speed? Have you located your local fibre cabinet? My guess is the neighbours getting higher speeds will be in the direction of the cabinet. Distance to exchange means nothing with FTTC. My brother had double my speed on ADSL, I now have double the speed of his fibre. Distance from the street cabinet is the main factor in determining your estimated speed.
First it was because they said I would and 1mb up is a pathetic improvement on a good adsl connection..
Now its because its clear my neighbours all have five or six times my upload speed.
I do know where my green box is. I can trace the phone line from it across the fields to the pole in front of my house where it splits to me and carries on further to my neighbours pole and then on a further 150 meters or so up the hill, through a bush and several tree branches to an even further neighbour who gets 30 something down and five up.
Of course it may be that the final stretch from the pole to my house is bad. Or the stretch of wiring to my master socket and bt may be only obliged to give me a bad connection. But if so you would think it would show up in my stats wouldn't you? I don't know for sure myself but I hope.
Anyway I have tried to sign up for mydslstats and will see in the morning if the old netbook I have left running managed to do anything. I'm not really sure what I'm doing but it may work.
Thanks for the thought
