Our FTTC 'went live' three days ago.
Due (I think) to the long line lenght TalkTalk decided a engineer was needed to install.
On the day a engineer visited in a hurry, covering for a sick colleague, swapped our old master socket for a mk3, plugged in the router, tried to get through to talktalk speed checker but failed, tried to get throu on mobile but failed, said "well your connected it will proboly be about 18Mb" then legged it.
Our estimated speed on the order was 7 to 12Mb, the guestimate from ADSLGuide was 7Mb, our speed is 5.6Mb.
Something that occured to me is that several years back an engineer needed to 'Profile' our line to get best speed, should the engineer installing FTTC have done something similar?
