How is this for BT 21st century BroadBand performance.

Which is true but it might be worth digging about to see if you can
get one of the older and possibly cheaper offerings.

As far as the speed (or lack of) is concerned:

How far are you from the exchange?
How much of that is overhead?

Can you extract some line stats from the modem?
Loss up and down stream
Noise up and down stream

What "ADSL filter" are you using?
How many?

Any extension wiring?
Topography of them? Loop in/out, star, combination.

If you lift the reciever on a wired phone and dial a single digit to
clear the dial tone are there any whistles, pops, crackles or noise?
Listen for at least a minute.

They have now turned on Interleaving to see if that will help ... have

Interleaving is normally automatic during the 10 day training period,
it can be forced on or off though.

Had an issue last week where download speed reported ok at 6.35 but upload
was 0.01 ! The overall performance was atrocious presumably as the link was
always waiting for acks or their modern equivilence from my end. BT
eventually sorted it after about 8 hours

We've got one like that waay out in the sticks;(.

Been like that since the word go .. which it sometimes does..

Still never mind .. we were treated to a magnificent pantomime
orchestrated buy Openwoe yesterday on a fibre upgrade. Total cock up the
whole thing from start to finish all 4 hours of it, then they had the
audacity to send us an e-mail saying that we weren't there on site and
now thats 90 quid thanks..

They got this AM a rather sarcastic mail which had the desired effect;!.

Lets see if they can get it right second time around, else I'm billing
them for my time which I think 100 sheets an hour is quite
reasonable;-?.....

A friend of mine had her BT broadband speed go down to 0.25Mb/s
download but 0.7Mb/s upload! After several days of conversations with
Mombai, eventually an "engineer" there said he would "reset the line",
and it miraculously returned to about 4.5Mb/s download and 0.7Mb/s
upload. I would love to know what this was all about.

I'm 500 metres from a modern exchange. I went from 1.5 to 15 when I
ditched BT in favour of PlusNet. (Took a little bit of hassling).

a bad line that gets repaired doesn't always get reset so when you have
**** performance the first thing is to reboot the router and start
looking at error rates. If they are low, get your ISP to reset the line.

Waiting. If the speed reduction was due to just a relatively short
period of noise (thunderstorm) the DSLAM should note the resynced
higher seed in a less than 24 hours and then up the BRAS rate. If the
speed reduction was due toa line fault that lasted a day or three you
might need to wait up to 72 hours. Trouble is the system can get
stuck with a noise margin that is far too high and sync speeds thus
forced down. The only way out is to get your ISP to get BT to trigger
the 10 day training period, this may or may not be a "line reset".

... looking at error rates. If they are low, get your ISP to reset the

You really need to know what the line performs like normally as error
rates, particularly FEC, vary from day to night. If the system has
got a stuck noise margin the error rates will be low and so will be
the sync rate but you need to know what the sync rate ought to be at
that noise margin.

So the line should be capable of better if it gets fixed.

In my case, the speed had been down for days, but went back instantly
after the reset. What does "reset" involve - can anyone explain
without using terms like 'resynced', 'DSLAM', 'BRAS' that I don't
know? I am but a lowly worm who has done electronics and software
design but has no telecomms experience.

You could try powering down your router.

There is plenty of information out there that google will find for
you. The "knowledge bases" of the more enlightend ISPs such as Zen,
A&A, Clara etc are probably the pages worth reading but not
exclusively.

My ADSL 2+ line has also done the ADSL in reverse trick a couple of times in the last year. Seems Openreach don't automatically reset the line after repairing the fault, as I had to email my ISP to get the training period restarted and the speed back up to my normal 12 down 1 up, not bad for a fairly out in the sticks location.

what happens is that when the negotiation happens wioth the DSLAM, the
DSLAM can enforce a nose margin on the router forcing it to go for
slower speeds and a presumed more stable connection.

resetting it removes all that so it starts at the most wild and woolly
setting and then proceeds to look at error rates and negotiate the link
down to an acceptable error rate.


Now I have seen that happen in real tiem but I have NEVER seen it go
back up.

Despite it allegedly being part of the whole deal. Ny synch speed on the
new router has been steady without variatin for over 9 months now with
no resyncs whatsoever.

I need a reset too, its too conservative. I used to get one every few
days before at a rather higher speed.

BUt its no big deal so its a job for a 'quiet day' when er indoors is
gardening so I don't get 'bloody internet's gone away' every few minutes
while it negotiates down.

No, is the answer. The second part of the answer is that you should do
some research. Look here for openers:

If you are a BT user aren't you supposed to test using their in house

You should have been on interleaving at that pathetic connection rate to
begin with. Something is badly wrong or you are at the wrong end of a
very long piece of wet string.

A fairly decent tactic is to report a POTS voice grade line fault and
hope that the basic TDR fault checker will find it. A dry joint or
leakage to ground (water in a connector) could do this.

Otherwise ask for your MAC and move to Plusnet or Zen.

BRAS is the fastest data transfer that the exchange thinks your line can
handle in practice. Sync is the speed that it has chosen.

Actual BRAS Sync

Reset has the effect of zapping the exchanges statistics and forcing it
to start again from a conservative geusstimate of sync speed based on
line attenuation. It then tweaks up or down usually every three days
until the error rate to speed tradeoff is acceptable. If things get
really bad it will enter a death spiral losing speed every time sync
drops out until it hits rock bottom. Sometimes it takes way too long to
come back up from there so a reset at the exchange is useful.

This might help by way of an explanation:
