Why has my download and upload speeds have been reduced in t

I just received the Report Card from Samknows for the month of March and I have noticed that my download speed has decreased from over 16+Mbps to around 12 Mbps and upload speed has decreased from 1.0Mbps to 0.5Mbps, my line SN margin has gone up from 3.0dB to 13.1dB. For the past 10 years or more I have had a download speed of around 16+Mbps and a SN margin of 3.0dB first with O2 and then with PlusNet when O2 was sold to Sky.
I live around 850m from my exchange and the distance from the exchange to cabinet (2) is 700m and from cabinet (2) to my house is 150m. I do not have any telephone boxes extensions. I have done a line noise test and there is no noise on the line. So I am no wiser as to why this decrease in download speed and increase in SN margin has occurred since February this year and what can be done to return to my original download speed and SN margin.

Any suggestions as to why this has happened?

Looks likely that higher target noise margins have resulted in reduced sync speeds

A line attenuation of 20dB is more inline with 1.5 to 1.8km cabinet.

The 'loss of' counters suggest something is up, its worth giving the router a complete reboot, power off, count to 10 and back on to see what happens to the connection stats.

I have now done a router reboot as you suggested above and the download speed has remained the same @ 12.3Mbps but the upload has increased to the usual 1Mbps.

The only new developing issue that I know about is that BT Openreach has install a new cabinet literally across the road from me although I did see them lay the ducts in the opposite direction to my house so I am wondering if they have swapped my line to this new cabinet and my line now comes the long way round! Would this explain the line attenuation of 20dB?

Who should I contact if something has gone wrong, PlusNet?

The new cabinet is the FTTC twin for your existing cabinet.

THis is confirmed by the top two sets of numbers in the speed checker that show you could get the full 80/20 service.

Regarding the drop in speed, it's possible something got disturbed while they were running the tie cables from the FTTC cab to the normal one.

Without knowing what the attenuation was previously impossible to comment

Perhaps these previous stats from 2014 can help

Notice that on these two sets of stats the SN Margin are much lower than at present!
My instinct as to what may have happened is that around the 22nd of February 2017 the BT Openreach engineer/s must have disturbed something in Cabinet 2 which is why the SN Margin and the speed have changed so much from previously and indicated by the SamKnows graph http://i1304.photobucket.com/albums/s524/scopio1/Feb... .

More likely that DLM has intervened, and changed you from a 3dB target SNRM to a 12dB target.

That would account for the change in speed.

Why would DLM do that? Usually because it saw more errors, or more disconnections.

Your attenuation barely changed, so it is not likely that BT engineers lengthened your cable dramatically. They might, of course, have disturbed a joint that is causing (or caused) your error or disconnection issue.

Just spoken to CS and they checked the system and did find that there was a problem and have said that they need to reset something (don't know what) and that it will take a couple of hours to see if that will solve the issue.

I shall wait to see if the SN Margin and download speed go back to what it was before otherwise I shall have to contact them again.

Correct me if i am wrong but....

If you want more speed sign up for FTTC you are currently

G.992.5

on ADSL(2+)

in Cabinet 2

You are not connected to a cabinet.

In reply to a post by ian007jen:

You are not connected to an/the FTTC cabinet.

It may not be live yet of course.

I do not need more speed or FTTC for what I do and can afford. I just want PlusNet to correct whatever has gone wrong and set my SN Margin and my speed back to what it has been for ten years or more.
I did speak to CS and they said could see what the problem was and that it would be sorted out in the next 2 hours, this was @ 15.30 and as yet nothing has changed.
I will call them again on Monday if things have not changed by then.

Edited by deleted (Fri 21-Apr-17 21:16:09)

Sounds like the openreach engineers may have inadvertently been causing errors etc.but there may be an underlying problem with your connection.

Plus net will/have/may reset the target SNR margin (back to 6 dB) see if your connection resyncs tomorrow; if it does not perform a reboot after 09:00 and before 18:00

Thanks for reminding me to do a reboot which I will do tomorrow.
I will post the result here tomorrow.

You may also just be suffering from the various connections in the street degrading. Mine did this when I was with BE and the engineer that came to my house found all sorts of connections in the chamber outside my front door that were "jelly crimped" about 25 to 30 years ago - and now starting to open up - causing crackling noises on the phone and major issues with the broadband. He fixed my line, but left the neighbours....

To day I had an answer from CS to my ticket stating "they have tested your line and have been unable to find any issues with it. The minimum estimate for your line is 16.5Mbps; this estimate is created based on the known length of the line, joints and materials used to create the line. The line is performing well and within the expected limits with a sync rate of 18.2Mbps."
My downstream has improved from 12.31 to 15.73Mbps and my SNM from 13.1 to 6.1dB my sync has gone from 14.335 up to 18266.
But my downstream has gone down from 1.06 to 0.35!
http://www.speedtest.net/my-result/6249659219
So there must still be some issues.

Your line has been reset to the Plusnet defaults for a new connection by the look of it. That has an upstream maximum of 440Kbps, which is what you have.

It is normally a single conversation with CS to have that uncapped and you should get over 1Mbps again. It isn't a line issue, just a restrictive setting ridiculous in this day and age. The vast bulk of their customers will never know, so PN save a fair bit of money over a year.

Edited by RobertoS (Thu 27-Apr-17 01:20:54)

Upstream sync is now 440 due to a snr margin of 32.6, hence a reduced upload speed. Definitely still some issues!

No. The SNRM is high fir the reason I gave. It is well known here and accepted by Plusnet that this happens. It was supposed to have been corrected a couple of years back, but we still see instances.

It is always 440Kbps.

Thanks for reminding me about that.

Hopefully the OP's connection will hold with a downstream target SNRM of 6dB - probably the previous (post 30/11/14) downstream SNRM of 3dB and 20.527kbps sync is now unsustainable on the line.

Certainly since VDSL2 was enabled from my cabinet error rates have increased on my ADSL2+ connection possibly due to interference on the D Side - my ISP (xilo) confirms that such a thing is certainly possible.

Today I have asked CS to uncap the 440Kbps which he had to put an order to do so.
I shall see what happens after midnight.
There seems to still be some issues if this graph is anything to go by.
http://i1304.photobucket.com/albums/s524/scopio1/201...

CS phoned back today @ 15.30 to inform me that they have now uncapped my upstream and my stats are now near but not what they were before February stats.

Oh dear. That's the other upstream cap they have. Corresponding to the old-style 832Kbps on ADSL Premium or whatever it was called, on the ADSL Max "up to 8128" 20CN products. I'm sure I've seen some people get the full open profile.

I suggest you ask on the Community forums, and see if one of the reps there can do anything. They have more powers than first-line support.

I could be wrong though and it can't be fully uncapped .

I have send a PM to Adam Walker as he has offered to have a look at my issue.

Thanks for all the help, I will post whatever Adam Walker says.

888kb/s is the normal upstream speed limit when the upstream is interleaved

Yes that is correct - I have these upstream "uncapped" stats from an old PN ADSL Max Premium account that I had back in 2011:

DSL Type: G.992.1 annex A

Data Transferred (Sent/Received) [kB/kB]: 0,00 / 0,00

Line Attenuation (Up/Down) [dB]: 20,5 / 35,0

SN Margin (Up/Down) [dB]: 9,0 / 12,0

Funny thing at the time was PN support wrongly thought that "uncapping" the upstream would affect the downstream sync - probably they got confused with Annex M. I didn't question that belief because they offered the "Premium" upgrade for free

I think Oldjim is correct (Sorry Robertos you can't always get it right!) it's nothing to do with ADSL Max premium (832Kbps sync) the OP is on ADSL2+ and 888Kbps is the maximum sync speed when upstream is interleaved. Modem is showing FECs for both downstream and upstream.

Edited by Realalemadrid (Thu 27-Apr-17 19:18:45)

On Plusnet Jim? Or on all WBC ADSL2+? Or on all ADSL2+ such as O2/Be, Sky, TalkTalk?

Edited by RobertoS (Fri 28-Apr-17 00:12:34)

The ISP has nothing to do with the sync between the user's router and the exchange so it's definitely every ISP using a service provided by BTw (I'm not sure about LLU ISPs who have their own exchange equipment).

In reply to a post by jelv:

(I'm not sure about LLU ISPs who have their own exchange equipment).

My TTB SMPF stats:

100% is not the case for sky and talktalk

As I said in my last comment I would update this post when I had a response from Adam to my PM in PlusNet Community but alas I have had no response.

Had a visit from an engineer yesterday he tested the line which he said was OK with no problems he had it reset to 6dB and capped at 440kbps which he said was preferred and changed the faceplate on the Master Socket with a newer version and to leave it for the 10 day training period.
Would appreciate your view on what he said about the line and the latest stats.

1) The engineer should not be doing that, (I don't know how he can anyway, because unlike FTTC it isn't Openreach's baby), but he may be misinformed.

2) It's a ludicrous suggestion that BT Wholesale ADSL2+ cannot run with an upstream even as high as ADSL Max (448kbps) or Max Premium (832Kbps)!! That 440Kbps is "preferred"?

I suggest you get back to Adam at Plusnet on both points.

The line still screwing up suggests a genuine fault, which this engineer may or may not have fixed. But the proper upstream sync of around 1100Kbps is not part of it.

Thanks RobertoS.

1) The engineer should not be doing that, (I don't know how he can anyway, because unlike FTTC it isn't Openreach's baby), but he may be misinformed.

There's an internal unit you call, staffed by OR but have access to Btw stuff, so can hard pin profiles.

2) It's a ludicrous suggestion that BT Wholesale ADSL2+ cannot run with an upstream even as high as ADSL Max (448kbps) or Max Premium (832Kbps)!! That 440Kbps is "preferred"?

Additional training required I suspect.

Re that internal unit, that's very interesting. No doubt on paper instigated by BTW with even perhaps a nominal charge by Openreach for providing this extra service. Which I'm sure would be available to Sky, TalkTalk, Vodafone and Zen should they request it .

The "further training required', yes indeed. What is extremely interesting however is that Plusnet used to default to this setting then stopped after customer complaints. They seem from a couple of recent threads to have reintroduced it. I wonder if EE also have it?

I suspect there is something in BTW capacity planning that yields more financial benefit than we lay people would expect. We tend to think purely in terms of the downstream. I wonder if the increasing emphasis on cloud computing and domestic cloud storage and backup has screwed the previous algorithms.
