Profile reduced
My profile was reduced from 7000 to 4000 on the 11th June. For the last 6
months I have always got between 6400 &7200 on tests. Now get between 3800 &
just managed 4200 this morning. Could uploading a small amount of data
(about 22kb) every 10 seconds 24/7 have caused or be responsible for the
profile remaining low?. Would it help to shut the router down overnight as I
understand that is when sync tests take place.

My connection has done the same ... at about the same date.
Went from the usual 6.5Mb to 4Mb.
I've sent Demon a couple of emails, but their only response is for me to
call their inbred cretin in "technical support".

Sorry for lack of info - no LLU - Plusnet, who responded quickly and say it
should go up in a few days or if it is stuck then get back to them. The
question I was interested in was if the data upload could be having an
affect as the problem appeared round about the same time I tried uploading
every 10 seconds. . If it is I could knock it down to daytime only or
increase the periods to 2 minutes. The data currently is 20kb every 20 secs
and 2 other lots of data every 120 secs all to different address's.

My experience has been that a short burst of noise can severely
degrade your sync speed.I look at my ADSL spectrum display
and it is as it's always been. It can take the best part of a week
before whatever algorithm they use sees that the noise has gone,
and sync spped suddenly jumps up to its former value, often a bit
higher, stays like that for a while, then drops back one step
to as you were originally, having found its preferred SNR figure.
Suspected, but not fully proven, if I swap in a different, spare,
ADSL modem, it sees a different box amy end, so forcing
a retrain. Then put the original box back, forcing another retrain,
and the sync speed is much better, but still takes a little while
before you get your highest sync speed back.
There are different makes of DSLAM so I can't say if they all
act the same, and their algorithms are a mystery, why does
it take so long to recover after a noise burst, yet it is quick
to respond to the burst.?

I've got a spare modem/router so if it doesn't go up by the weekend I'll try
swapping them and see what happens - thanks for that.

Even though I have the problem just now I cannot fault Plusnet for their
tech support - I left NTL/Virgin after being with them 8 years due to
support with extremely low speeds (quite often a low as a few hundred kbps)
and have had extremely quick responses to any queeries. They even got me
migrated in about 4 days just coming up to Christams eve when I was having
trouble migrating to the Post office broadband who had a software problem
with their ordering system and were going to take at least 7 weeks with no
promises even then. I have only had a couple of dropped connections in the 6
months and no drop in speed until now so as long as the support stays in the
UK then I will be staying with Plusnet.

The MAC issuing desk is still in the UK, and a model of efficiency. You get
a code within a few minutes. Its a shame the rest of their helpdesks are
rubbish as one wouldn't then need the MAC one.

Mike,
AIUI the DSLAM adaptive system takes a series of line drops (10 inside
one hour period I have heard) as symptomatic of a noisy line, and
increases the target SNR from the basic 6dB to 15dB. This results in a
significant reduction in sync speed.
The slow recovery (requiring stable periods of a week or more) for a SNR
reduction of 3dB is a (presumably) deliberate attempt to ensure that
lines subject to intermittent noise do not yo-yo. Someone (BT?) having
decided that slower but stable is preferable (i.e produces fewer support
calls) to fast but erratic.
If you check your router stats you should see that the SNR is sitting at
(probably) 15dB. If it is then something (a longish period of noise)
caused your router to retrain multiple times over a short period, and
the DSLAM reacted - I had this happen with a mains glitch which caused
my router to misbehave.
If its sitting at 6db, then you have had a change in the line quality.
When the data transfer started, did this coincide with a new device
(webcam?) A dodgy (electrically noisy but working) device PSU can
generate incremental noise at ADSL frequencies.
Regards.

I've got a similar thing going with Plusnet right now. My speed (long line)
used to be 2 to 3.5 Meg but has dropped to - and stuck at - 1.5 to 2 Meg.
Over the last couple of days they've been thoroughly investigating and have
now referred the problem to BT (expected update tomorrow morning).
They've been very good with feedback so far.
Keeping fingers crossed.

YES. That's the problem. My understanding is that BT changed the way the DLM
operates !
Can anyone confirm this ?
My BT1801HG is capable of 2.8Mb/s on 6dB SNR and 51dB att. ~95% of the time.
We get random noise spikes and even though the router works down to
2dB SNR, it does disconnect every 3 or 4 days, but almost always re connects
straightaway.
Previously it was possible to bring it back 'up to speed', whenever the SNR
got over the 6dB threshold, just by re training the DSL.
However, lately it won't, I even got my ISP - PlusNet to reset it back down
to 6dB,
but it has since climbed up to 12dB and they REFUSE to do it again. They
said it should be left alone for at least five days, but it just doesn't
stay up for that long !
I am now stuck on synch of 1.8Mb/s, but actual download speed of 0.8Mbps.
Quite simply I am prevented from making the best use of my connection. It's
MY connection and I should be able to chose between slow and steady or fast
with drop outs, which happen anyway !
If my car would operate at 60% of it's capability, I could get it replaced
or get my money back.
How can we get BT to listen ?
Otherwise the only thing I / we could do is switch to mobile broadband !
Thanks, regards,

Have you attempted to get your ISP to raise an engineering visit because if
you are dropping with in days a APTS result should show errors so the
engineer should go looking for the problem. The reason I'm asking is that
BTs kit will work to the most stable connection speed it can give you,
automatically, so it's the drop outsevery few days which is the problem not
BT screwing your speeds down. Yes it should train back up after a few days
but by that time, by your own words, it's dropped out again so it will not
do so. Find the cause of the drop outs find the cure for your low speed.

One short burst of noise from an untraceable source and
you are down to dialup speed for a week, or longer if
another burst appears.
Most would prefer an short burst of high error rate, which
error correction can handle, than long periods of slow
connection.
One thing though unproven, is that if you swap in a
different modem, if forces a (new box at the other end)
retrain, then swap the original router back in, forcing
another retrain. Sometimes works. Worth a try.

Anything is worth a try I've even known line tests to force a retrain in the
past.. Problem is that a retrain can go either way..

HOW ?????
Thanks for your reply.
This is an ongoing problem, since ADSLMax started.
We had periodic problems, sometime lasting days, sometimes weeks, whenever
we asked for the line to be investigated, the line was 'within limits' and
we were threatened with extortionate charges for BT visit.
As we could always eventually bring the connection up to ~2.5-2.8Mb/s at
6db, we lived with it, but now we are STUCK at 1.6-1.8 Mb/s / 0.8Mb/s actual
download and min 12dB SNR :-(.
Just had an email from PlusNet:
THIS LINE IS STABLE AND WITHIN ERROR/RETRAIN LIMITS FOR THE CHOSEN SERVICE
OPTION (ILQ=A)
Fault Threshold Rate 921
If your speed drops below 921kbps then we can investigate this further !
I can't see that changing ISP would help, the problem is the c**p quality of
BT 3.9km long line !
Apparently O2 / Be LLU is coming to our exchange soon, but would they do
something about the line ?
The way I see it is like this:
BT claims their CAR will do 'up to' 80mph.
When you drive the car is misfires and repeatedly cuts out at 28mph.
When you complain, instead of fixing it, they limit the speed to 18mph !
Law says you should be able to get it fixed, replaced, or get your money
back.
But BT is the only game in the country and you need a car....
Bring on WIMAX, LTE, whatever !

Re: Profile reduced
> This is an ongoing problem, since ADSLMax started.
Buy a cheap ADSL only Draytek Vigor 2600, cheap
enough on eBay, and give it the long/difficult line
flash, this improved things for me, but it might not
for everyone, but either way the DSLAM will
be forced to use ADSL not ADSLmax since the
modem doesn't support ADSLmax. DSLAM's
seem to be backwards compatible to support
ADSL, otherwise we would have had to buy new
modems. Not sure if the 2600 had a wireless version,
I'm Cat5, with the 2600 next to the master socket.
I have an ADSL+ BT Voyager 240, but although
it's ADSL+ it syncs slower than the Draytek with long
line flash. Think I'm actually on ADSL+ 8Meg its just
that I'm forcing it to run ADSL, more stable and faster
in practice.

You will only get what your line supports,
that said the line might have a problem, bursts of
noise, water in the underground 200 pair, dry
joint, drop wire (if any) acting as an aerial,
local after the master socket problem.
Did once investigate a problem where the
drop wire rested on a sodium street light,
and had slid up against the ambient light
sensor. So every night there was a high noise
level most of the night, it never retrained to
a higher speed, but could be forced to, by
swapping ADSL modems, not that it was
much help, it was stll at dialup speed every
evening.
Don't know where the drop wire was
originally, council however recently
resited the street lamp and put in a
pedestrian crossing, so that may have
triggered the problem. Don't know how
you get that fixed if council says we don't
move street lamps, and BT hasn't another
convenient pole.

Similar problem to mine, had burst of noise due to dodgy mains supply
and router went into a funny state. Happened about 0030 in the night.
Resynching continued for hours and eventually gave up. Router power
off/on brought back the synch ~1400 but at a 12db SNR. Normally
synched at ~2300 kbps. (Just enough to get me a 2M profile. I am a
long way from the exchange).
ISP investigated and sent me the logs of the continual resynching and
said the line should go back to a 6db SNR. They also said that BT
wouldn't look at setting the SNR back to 6db as the "line was within
limits". It didn't go back to 6db SNR after three months of stable
running (I fitted a small UPS to the supply to the router). It was
stuck at 12db. Several calls to the ISP resulted in the same answer -
it should go back to 6db by itself. So I gave them (ISP and BT)
enough rope to hang themselves. I just lived with the slow speed for
three months.
After the three months I asked ISP what they were going to do about
the failure to resync at 6db. Passed to next level of support who
actually called me on my landline! The problem was discussed and the
cause and reolution by UPS on the router deemed acceptable.
The ISP moved me to "some other equipment" where they "could alter the
line parameters" if necessary. After this it resynched at around
2200kbps (which it did with BT at 6db SNR before the problem) but at a
9db SNR! The only only difference I note is that the upstream synch
is now 736kbps.
I guess they moved me to some LLU equipment in the exchange. I was
happy about this because if this move proved to cause other troubles I
could get a MAC and go elsewhere, even back to an ISP who used BT
stuff in the exchange.
Just staying on the BT stuff in the exchange with the 12db SNR and
changing to an ISP who used the BT stuff would achieve nothing. I
would still have been stuck at the 12db SNR.
However there have been no further problems so I stuck with the ISP
and I am happy, the line seems to be more stable than it ever was when
I was connected to the BT stuff. (Monitored with Router Stats).
Though I dont know why that should be. Maybe because the target SNR is
9db.
For you, changing ISP and using LLU (or a different LLU) might be an
option as it will get you moved to someone's else stuff in the
exchange. Though you will need an ISP that will take an interest in
resolving any problems you may have with your line. I can't help you
on that one. Others here will have had experience with their ISPs
getting line problems sorted.
During my trouble I did look at moving to Be/O2 put when I tried their
broadband checker it said I couldn't have their broadband. So I
called them up and apparantly I am too far from the exchange for
*their* broadband. Over 5km I think they said when I gave them my
postcode.

It would appear that they have a policy of not providing service to anyone
who won't gain an advantage from ADSL2+ because of long line difficulties.
In other words, they are forestalling future complaints from people who
might want to migrate, thinking that things will improve - and they
don't/cant.
As I understand it, the "up to 16Meg" service only improves speed on short
lines. If you're on a long line, it might even get worse than it was under
ADSL Max.

I assumed it would be something like that. Which sucks frankly. I know I
have a long line. I also know ADSL2+ isn't likely to do much if anything.
What I would like is to pay £12.50 per month instead of £19.99. Quite why I
can't join makes no sense to me as I'm the perfect customer. Happy to pay
the prices and can't use up loads of bandwidth!

What does APTS stands for, what does it do, and how do you find where the
problem is ?

I HAVE 2600VGi, with long line firmware, used it for years, but after long
spell of disconnection problems last autumn PlusNet gave me the BT1801 HG to
try.
I synchs at higher speed, works down to 2dB, and the WiFi is better too, so
I was quite happy to use it, (despite the software and facilities being
inferior to the Draytek and loosing VoIP).
However all that has now been negated by the min 12dB SNR enforced at the
exchange. I think that will still apply to the Draytek, will swap them just
to see.
Can someone confirm that ADSLMax won't work with plain ADSL modems ?

I'll hold my hands up & say that no one has taken the time to actually tell
me, which is partially my fault because I have never asked. Being so used
to 2, 3 or 4 letter anachronisms you tend to say ok, & just get on with the

No idea what APtS stands for, but you can download a version of it from
here: http://www.buzzhost.co.uk/downloads/APtS_PW_IS_broadband.zip The
'zip' password is 'broadband'. It requires a BT Voyager 105, with drivers
installed before hand.
It bitched at me about licences being out of date, but still worked.
It will show you errors etc, but there is very little you will be able to
do about it. Kraftee may well have a later version of it - but I don't
expect you will be able to pry a copy out of him ;-)

OK, getting there...
Do you test at the clients site, exchange or in between ?
So what does it tell you ?
What do you do then ?
I need to know more then the guys at the ISP to get them to talk to BT.

Update:
Far from improving my speed, Plusnet got BT to improve my SNR, due to noise
on the line. This has resulted in an even slower speed, which is now stable.
It might sound stupid but I was happy with the occasional disconnection,
provided that my speed increased to what it was (up to 3.5 Meg).
It's now a steady 1.8 and not going anywhere else.

The one you're interested in would be at site, that is your home, normally
done from the master socket after it has been changed out for the newer
version. It can be used anywhere in the network between you & the exchange
to try & locate problems causing excessive erroring on your line (although
the line test perfect electrically).

Well it is cheaper than them paying Openreach to go to site (possibly a
number of times) to try & pin down what is causing the excessive errors.
I know that there is a group of people who don't mind the occaisional
dropouts but the basic service is aimed for the most stable connection
possible, hence the increase of your SNR threshold (to possibly 12 or 15dB)
in order to make it stable. Do what you can to tweak your line, faceplate
filter, good quality extension wiring etc etc...if you can improve your end
you would have the leverage to get them to reduce your threshold & possibly
increase your speeds again.

There is a tool called DMT that will allow you to tweak the SNR on
compatible routers to achieve a better sync rate.

If they have set your SNR threshold in tablets of stone,
at an unrealistic level, then you have a problem.
By experiment I have found I can force a retrain by swapping
routers. I'm assuming when the connection starts up there
is a handshake, what do you support, ADSL, ADSL+,
what's your received signal level, SHR, and so on?
So I swap in an ADSL+ modem, then an ADSL only
modem, that has a long line UK2 flash, forcing
retrains, and my speed rises. The ADSL only
with UK2 flash gives the best sync speed.

Thanks for the tips.
I may well get a faceplate, disconnect bell wires, etc, if that's the only
way forward.

Might be worth looking on eBay for a cheap ADSL only router,
non wireless, with low postage.
As everyone wants wireless, and the faster, current production
modem/routers, the old ones, are going quite cheap.
I assume your PC has a network RJ45 connection, or
a network ethernet card.
If not you'll just have to stick with the USB, although
these aren't noted for best performance.
OK for short, low attenuation, good SNR lines
(quiet - not long enought to pick up much noise)
lines, but not ideal for the longer high
attenuation, poor SNR, lines.

It could be, best guestimates for this line stated 3.5Mbps (IP profile
3Mbps) with fitting a faceplate filter, using a ADSL2+ patch lead (both from
ADSLNation, yes I didn't get one off the van) & generally putting the rest
of my extension wiring into better order I now have an IP of 5Mbps with a
sync rate which seldom falls below 5.5Mbps. So it can be done.

None of my routers are on the list, which appears to be pretty old.
The newer Drayteks have that build in, but
are you sure that the DSLAM at the exchange will take any notice of that,
or will it stick with the BT decreed profile ?
Thanks, regards,

Well, that means an openreach visit at £180+ !
The trouble is we got interminent line spikes / disconnections, sometimes
every few hours for weeks on end, mostly every 3 or 4 days, sometimes it's
OK for several weeks.
It could take days to track down what's causing it....:-(

It certainly can be done.
I hada HUGE issue whenI wento ADSL max. Connections were fast but
flakey. By SNR ended up at 12db at te DSLAM and it ws still falky.
After several days of net research I discovered the telnet interface,
and started changing every parameter in sight: one was something like a
'turbo' switch..cant remember what it was called. I switched it off and
immediately dropped speed by about half. I now am at normal operation.

SNR ratio at the DSLAM has to be manulally reset.

yep. I got a Dlink 504 for peanuts.
Does need all teh latests firwmwre patches and a turn off of the turbo
functin tho.
Buta new netgear is only 30 quid or so IIRC.
