Steve, thanks for your reply.

I think with IDNet at present the method of install is an engineer visit to install the VDSL modem, ...
Oh no ...
Never again ...
When we were migrating from Orange to IDNet, several different BT engineers came several times to our house on a single day !
It was a nightmare !
Only the last one knew what he was doing so after checking few things he drove to our exchange and within 10mins or so the issue was solved.
After reading some more about the FTTC I realised I do not really need more speed - we don not watch films online, we do not play games online ...
All we need is a bit larger download allowance.
I think I will stick to ADSL2+.
I do not want anybody messing around in our house, playing with internal wiring which is nicely hidden under plaster boards, putting some dodgy extension cables around the house, modems ... brrrrrr ... no way ... for a sake of some increased speed that we do not really need ...
