So, this is a bit of a post-necro'ing, but I thought it might be interesting for some.
Recap: My FTTC was rated @ 35-57 down 4-7 up in the line checker back when I first got it installed. Using the BT "free" upgrade my infinity1 sat nicely at 55/7 typically. But then, my neighbour got connected.. and that caused my connection to resync to 43-45. They switched their router off at night, which allowed my router if rebooted to sync back at 55, until next they switched on. Through advice in this thread, I was able to throttle sync to a stable 52 succesfully for quite some time. Eventually though, I got re-banded to I'd guess 50, as sync would lock at 49997 or some such, and that was that.
2 months ago, fleeing another price hike, I switched to plusnet unlimited/uncapped. DLM released me, and I initially connected at 57, but neighbours soon put a stop to that, and I'd get dropped to 45, I tried to catch them during off periods and reinstate the throttling of before.. but it just would not work for some reason. Alarmingly, when I checked the line speed estimator, it now showed my line capable of 40mbit at best.
Then something odd happened after a few days, I resynced at 50.. and neighbours rebooting router no longer affected me. Long story short.. Vectoring got enabled.
A week later, and here's where we're at:
Dn Sync: 67, max attainable: 72.
Sync has been rising throughout the week, I thought I was doing good at 57, then it was 62, 65, and now 67, every few days a resync higher. I just wish my upstream was better
