Hello all
We have had FTTC here since 2015 (no FTTP available - WOODBRIDGE Cabinet 2).
Its always been slow (35/5) but with low latency (8ms ping to google / bbc / 8.8.8.8), which is important for some real time sound work I do.
On Friday last week, a fault developed, and the internet dropped. The hub probably got power cycled a good 10 times over the weekend from various family members 'checking if its come back'.
BT fixed the fault Tuesday, but since coming back on, latency has more than tripled.
Looking online, i have seen mentions of DLM and interleaving (i dont pretend to know any more than that!). From my understanding, DLM can kick in and enable interleaving if a line has instability, or a modem gets repeatedly power cycled. The system should readjust automatically after some unspecified time IF THE INSTABILITY IS RESORTED.
Now heres my issue - i currently have to travel into the office to do latency intensive work, which is expensive and inconvienient, so i am extremely keen to have this back asap, but if this issue is NOT DLM / interleaving, i could we be waiting for ever for it to 'reset'.
I have a HH5, ( and a currently disconnected HG612 modem - disconnected as it was an ebay purchase, and i figured 3rd party hardware might complicate BT recognizing the fault), so i cant see any way to actually test this.
Here are my HH5 stats:

Is there any way i can confirm DLM has activated interleaving, and that i should expect it to return to normal at some point (and ideally wether thats 1 week, 1 month etc)?
I also understand that i have no ability to actually request interleaving turned off on FTTC, but perhaps (hopium) thats no longer the case?
