Connection to Zen resolved during 16th Nov - there was a mention of the problem being an incorrect VLAN setting somewhere in the provisioning system.
Many thanks to the various Zen staff for their efforts and putting up with my frustration and occasional rants by email, forum and phone over these past 3 weeks.
Since both myself and my contacts within Zen were convinced that provisioning was the problem all along (especially as the clues were there on the day of the original upgrade) they way in which BT have gone about resolving this matter is an utter and total farce. Mysterious line faults were discovered and resolved, multiple visits were undertaken to my locality, by up to 4 mobile technicians, before someone at a computer terminal decided to spend a couple of hours investigating what they had been told all along.
What a way to run a monopoly!!
I am not sure that I understand your explanation. When I had FTTC installed, OR left me with a working modem. I assume that this was the case with you? For my part, I put the modem back in its box and fitted my own VDSL-capable modem/router. During the set up, I had to configure VLAN to 101, set PPPoE in the GUI, enter my Zen username and password and that was it. Just in case this type of problem impacts on others, I would be interested to know where 'in the provisioning system' something might have gone wrong? If it was back at the exchange, then surely this type of problem would impact on one than one user? If it was at the time of installation, then FTTC would not have worked at all.
Edit: FWIW, the simplest way of checking the serviceability of an FTTC modem is to plug a laptop/desktop directly to it.
