Fibre fault, now slow upload rate

I've had talktalk fibre service since last December, and it has worked 100% reliably until a week ago. I used to get 23MB down and 2MB up sync rates, with speed test results to back that up. A week ago my service went off completely - my Draytek router lost sync and couldn't reconnect. Now it work intermittently with my Draytek router, and reliably but slowly with the talktalk router (HG633).

 

I phoned talktalk support who did a line test and confirmed that there was a fault on the line. It was escalated to Openreach, issue ref no: INC000013346256, and my line number is in my profile. Openreach engineer came out (even though I'd called talktalk to cancel) and tested the line, said the measurements were all good. His test equipment synced at 20MB down and 2MB up, just like my Draytek router does. He also reset the line profile, in case DLM was affecting it.

 

My talktalk router will only sync at 0.5MB upload, which is clearly abysmal - I used to get 1MB upload on adsl. My Draytek router worked again for a couple of days (at 2MB upload), then lost connection and couldn't resync. Line stats from the talktalk router:

So why will the talktalk router only sync at 0.3 to 0.5MB up speed? Why does it report 0.5MB as max attainable up rate, when my Draytek worked for months at 2MB and the Openreach enginer's test equipment also synced at 2MB? Why does my Draytek router keep getting thrown off, and refused resync?
