It's only had eight days so far though.

It doesn't remove interleaving that quickly, and without a lot of shenanigans I don't think an ISP can request it. ISP-triggered DLM resets are normally only when an engineer should have requested one after clearing a fault, and didn't.

I think its down to error counts.

In the summer season my line generally runs without interleaving, and in the wet winter, interleaving is added and stays until the summer. It took about 2 weeks last year to remove the interleave.

This year I migrated to plusnet (2nd June) about the time it would have started to get reduced error counts, and the move reset the line (probably because I went from 80/20 to 40/10 and had to be kicked back to 80/20). Since then my connection sync speed has been 55790 down and 9183 up with no interleave. I've previously seen lower down and higher up - but with interleave enabled.

DSLstats tells me my ES/hour are 52.2 on download and 1.07 on upload. On the 40/10 profile I was 0 on both.

I am still thinking that a DLM profile change initiates a reset.

But no isp's seem to try it (maybe there is a deterrent in place?).

Also there is the option of changing the openreach product e.g. down to 40/10 then back up to 80/20. Plusnet probably don't do this due to it also initiating a new contract and possible setup fee's.

I seem to have a vauge recollection there's a charge of £10 for a profile/product change.

It's would cost more than £10. Because they have to change product order via BT twices from downgrade to 40/10 then upgrade to 80/20. So, it probably cost £20. But, changing product is pointless because I don't think openreach willing to reset DLM at the cabinet.

I have raised a Question with PlusNet so will wait and see what they say. I will leave the connection alone and see what happens, I'll see if there is any change in the next 2-3 weeks.

It's annoying because for just over 2 years prior to the UPS fault the line has been perfect. 79999 sync and fastpath. I have also swapped modems in the past ( testing a spare I got from eBay) and DLM did not notice.

Not to hijack this thread, but in a similar situation. Went on holiday so left router powered off for a week. Came back, and noticed it sync'd at a slower speed. Reset a few times, but no joy.

Am now gonna leave it the 10 days.

But what I've also noticed is that the BT Adsl Checker has actually dropped my estimated download from 15.5 to 11

This all seems to have also occured now the infinity cabinet is live (And have it being installed 29/7).

Has anyone else ever seen the BT Adsl Check website reduce their estimated download speed?

It has been nearly 19 hours since I power cycled the modem and in that time I have a downstream ES:2 and 5 for upstream other errors are not particularly high either.

It is also important to not that lots of people keep resetting their modems to try and get better results... The problem with that is the DLM will see it is further issues. The DLM doesn't know you are trying to get it back to a faster state. The disconnection counts are adding up. For anyone who was on Fast Path and it 'was' stable before, just leave it connected and stable. The connection in 99% of cases will go back to Fast Path after around 9 days.

Yes, that's why I left it 8 days before power cycling it (and only once). Unfortunately FTTC DLM is controlled by OpenReach who seem to be a law unto themselves.
