Two weeks later, it was all done!!! YAY.
With bated breath, I logged in a did a speed test. Result before, (with ADSL) ~5Mbs, after (VDSL) ~ 6.2Mbs - wow!!!!
What an anticlimax. I have been on to tech support and we have tried various things but that is what it is. And, yes, I am plugged into the test socket.
The odd thing is that the BT wholesale speed checker tends to give results around 10Mbs (sometimes it's as low as 6 but 4 out of 5 times it's 10 or even a touch more).
I have tested with TBB speed test and Ookla, same result. If I download one of the TBB test files, sure enough, around 6.
I'm about 1500m (by road) from the cabinet (which, ironically is a about 100m the *other* side of the exchange).
The ISP says that they can't log a fault with BT as it is within the "tolerance band" or some such excuse.
So, is there any point to FTTC, is it all a just a big sham???
By the way, if I try to run the 'further tests' on the BT speed-checker, it fails with the message 'The Performance Tester is currently unable to run a speed test for your broadband connection.'
