Re: Sudden Drop In Speed

Hmm, just yesterday when I tested your line you were on a 3db profile getting around 75Mb.

It could be possible that the drop you experienced caused DLM to make changes to the profile.

I'm not in work at the moment, what's your speed estimate showing at www.dslchecker.bt.com?

Re: Sudden Drop In Speed

Is there any fault showing on my line that may have triggered the DLM

Re: Sudden Drop In Speed

I've tested your line and I'm not identifying the cause of this. The profile the test is showing is actually still 3db. Seems that it's not as much as DLM causing this, but something else impacting the speed.

 

As the downstream sync is currently below your estimates I'd advise to try the test socket if you haven't already: https://community.plus.net/t5/Library/Testing-From-The-Master-Socket/ba-p/1322242


And then raising a fault to us at http://faults.plus.net

Re: Sudden Drop In Speed

Re: Sudden Drop In Speed

Yeah the product is still 80/20. In this case I'd recommend raising a fault as we'll likely need to arrange an engineer to investigate this.

Re: Sudden Drop In Speed

I cant see anything else that would be causing the drop though i don't think openreach would look into it as according to the checker it's within there estimates therefore an engineer charge would be applied,

Re: Sudden Drop In Speed

Hmm, when I checked half an hour ago before I left the office you were below the Clean estimate range.

Are you looking at the Impacted when you go to www.dslchecker.bt.com?

Re: Sudden Drop In Speed

The downstream sync is below the clean estimates so we'll be able to raise a fault to BT wholesale.

Re: Sudden Drop In Speed

I'll give it a few days see if DLM increases it although i can't hear any noise on the line after doing quiet line test from the test socket ,if it's no different by midweek then i shall raise a fault ticket.

Re: Sudden Drop In Speed

I know Openreach are trialling 3db profiles in select areas i wonder if the OP is in one such area.

I believe if the 3db profile causes a problem it should automatically go back to a 6db one but i'm not sure if that is a immediate thing and it failed to do so, or it's something that happens over time.

If indeed it is a trial there might not be anything the OP can do as it would be in the hands of Openreach to sort out in the time frame they have laid out for the trial, Plusnet could let them know something is up but whether they would act on it i don't know.
