My experience with IDnet over the last 3 years. after moving back to my house post divorce:
ADSL: 6 or 7 support calls moving speed up from 2Mbps unreliable to
6,5Mbps reliable.FTTP: 1 support call to tell me how to set up the router PPP interface to them..
Now am not saying that FTTP has given me smooth seamless uninterrupted internet access, but none of the issues have been with the last 15 miles.
In short FTTP has been a total 'fit and forget' experience - far more so than neighbours' FTTC, where VDSL routers fall over lock up. etc. Mind you I bought my own router and paid a lot for it.
And I am getting a pretty rock solid 34-38Mbps with actual download speeds >4Mbps from it.
