New Plusnet Extra Fibre speeds

Hi Plusnet,
Had fibre installed this morning and so far very impressed .    However the download speed is only 40m ( yes I am being greedy )  at the moment and I was expecting between 60-80 ..
will this automatically increase over the next 10 days or will I have to call after the bedding in period to have it increased.
Thanks

Re: New Plusnet Extra Fibre speeds

Run the BT speedtest - diagnostic version and report the IP profile

Hi Oldjim
  IP Profile for your line is - 77.44 Mbps

Congratulations - that is as high as it gets!
What does it say here for Current Line Speed?

Re: New Plusnet Extra Fibre speeds

And how much usage does your View My Broadband Usage say?

Re: New Plusnet Extra Fibre speeds

As you only had it installed this morning it will default to the highest profile and will come down as your line trains throughout the next 10 days.

Re: New Plusnet Extra Fibre speeds

Fibre's DLM sets the line profile after monitoring for 48 hours - and triggers a resync if a speed or interleaving change is necessary. I've seen this in BT documents, and had practical experience of it happening. I haven't yet seen any evidence of a 10 day period...
Any other involvement of DLM seems to cause resyncs between 4AM and 8AM.

What are you using to test with?
BT's tester can go flaky sometimes, while the Plusnet one seems to be flaky more often than not. Speedtest.net is usually OK, especially if you select one of the major servers in London.

Re: New Plusnet Extra Fibre speeds

Also, don't think this has been asked, are you testing via wireless or an Ethernet connection ?

Re: New Plusnet Extra Fibre speeds

If the answer is wireless I am going to get a large hammer out  Smiley

Thanks all
I have Ben testing wired , no hammer necessary
I will monitor over the next few days and hopefully
See an increase

Re: New Plusnet Extra Fibre speeds

From my experience I would say an increase is unlikely, generally it gets slower as DLM kicks in. You are on the maximum possible BT and Plusnet profile, so ought to be getting download speeds of around 75Mbps now. If you are only getting 40 that suggests something is wrong somewhere. Can you confirm what speed you get on speedtest.net?

I first read that when I downloaded BT's SIN 498 document in August 2011. The latest version I have was updated by BT in July 2012.
I still believe that to be generally the case, although I have (on reflection) recently ceased stating it to be rigidly the case.

Due to many engineering visits where physical external cabling works such as replacement drop wires, lifts & shifts etc. have been carried out, my DLM profile was reset via the engineer's request a few times.
On these occasions, I did see an uninitiated resync at a lower speed within the 48 hour period (usually around 5am), but Interleaving, INP & delay tended to SOMETIMES remain OFF beyond 48 hours - for almost 8 days on one occasion.
On each occasion, Interleaving was eventually switched ON, which obviously substantially reduced UnCorrected errors & also substantially reduced Errored Seconds.
My connection is now permanently stable again, no longer frequently resyncing "on the fly", with DS Interleaving depth varying slightly between 400 & 500 whenever I have needed to reboot the modem during home refurbishment works (all power turned off), DS INP at 3.00 & DS delay at 8.00.
So, perhaps my empirical data does confirm that the 10 day training period does still apply (sort of, to some extent, for some connections).
SIN 498 also states that DLM is an ongoing process anyway.
From my experience, unless there is a complete loss of service, BT refuse to send engineers out within the first 10 days.
"2.2.1 Dynamic Line Management
Dynamic Line Management (DLM) is employed in GEA-FTTC. DLM constantly manages lines to maintain a target link quality (speed and stability). It does this for as long as the product exists.
At provision, the line is put on “wide open” VDSL2 line profiles allowing the upstream and downstream line speeds to run at the upper limit of the product option selected.
On the first day of operation, DLM will intervene if severe instability is detected. Otherwise, DLM will wait until the day after provision before deciding if it must intervene, provided that the line has been trained up for at least 15 minutes during the preceding day."
& so on...............

Re: New Plusnet Extra Fibre speeds

Hi dizzler,
I have checked your sync speeds and they are currently sat at 77MB/s, so 40MB/s is quite some way off.
Are you connecting wireless or wired?
