I was told that tests showed the problem lay in my premises, it will cost £xxx if an engineer comes out etc. but nevertheless I did have an engineers visit and an external joint was replaced and the rest of my line checked and found to be in order. Things didn't improve.
I finally replaced the Plusnet Hub One with a Fritz!Box 7530 and with the default settings got an immediate improvement.
Various changes that I've tried made little difference except for one which I don't entirely understand.
In the connection settings there is an option entitled, "Delay disconnection by provider to the period between" with a drop down box after it to allow a choice of a 2 hour period. I have mine set at 3-4 i.e. between 03:00 and 04:00 hrs. I'm guessing that by "provider" it means of the connection to the cabinet and not Plusnet.
Every night at about 03:15 hrs the router log shows "Clearing internet connection briefly to prevent the internet service provider from disconnecting you in the immediate future." followed by "Internet connection cleared." and then "Internet connection established succesfully." together with my new IP address gateway IP and other info.
If I untick this option then my connection drops once or twice a week and the re-connection takes anything up to 10 minutes If I have the option enabled the new session is started with 1-3 seconds.
The downside for me seems to be that the downstream SNR rises slowly day by day. At the moment it is wavering between 14 - 16 dB and my download speed has dropped from around 45Mbps to about 36 Mbps, this being nearly 9 days after a re-sync.
Have my observations lead me to a false conclusion that I can control whether my line re-syncs or not ?
p.s. apart from the obvious fact that I can re-boot the router to force a re-sync
