Hi guys
Up until 4 weeks ago I enjoyed 2 megs bb from Tiscali, it was great, on it for about 2 years, then suddenly it went right down the pan.
Contacted support and spent 2 weeks talking to our Indian friends and getting nowhere. It was only after a heated discussion with a team leader that he admitted
that no-one had investigated my problem as they could not get slots with Openreach Engineers, as BT were pulled out.
At point I requested my number and jumped ship. Deciding it was best to go with the infrastructure specialists I went to BT and ordered Total Broadband 3 and talk.
That went in on the 27th November and ever since it's crawled. I had a line engineer over to check the line and he said it pegged out at 2500megs, which is what the IP profile is saying. He fitted a master broadband socket and said he could do no more, I would have to let it settle.
Well I've waited and nothing seems to change, it gets no faster. Apparently something, I know not what, was done at the exchange 3 days ago, but nothing has made a difference. Also I've reset my hub 3 or 4 times since then, and now wonder whether I've reset the 10 day period for line training....or whether the line has locked up I don't
know. Below are my line stats, I've checked Nildram site and apparently my exchange is a dsl max exchange and when I checked, was not choked with traffic. I was getting about 150-200 kbps at best.
I have good cables, not cheapies, both computers are cookie, adware, virus and free of bloatware and normally slick.
My xp machine has the mtu tuned for Tiscali although it may not suit my con now, but cant get a good enough con to even consider tuning.
I read up a little on adaptive adsl on the main site ( excellent site btw) and learned the difference between fixed and the latter, but don't really know what to expect now.

Any help greatfully received, sorry its an essay

Hi and welcome

Ok The good news is that there appears to be nothing wrong with your line .

with your attenuation    Line attenuation (Down/Up) 57.0 dB your  downstream connection is spot on

see link below
http://www.kitz.co.uk/adsl/max_speed_calc.php

your noise margin is normal at 6db

Your profile at this synch rate will be 2500Kbps .

can you run speedtest on btspeed tester to confirm that .
http://www.speedtester.bt.com/

I think your problems are simply congestion. you can verify this by doing speetests at different times of the day .
http://www.speedtest.net/

Do not keep trying to get a better connection as this migth result in your line being seen as unstable .this could result in increased target SNR and a lower connection speed.

Hi Jeff

Many thanks for the reply, I did check exchange data on the Nildram site and my exchange got a green light?
But after the last router reset, I seemed to have picked up a boatload of upstream errors..

FEC Errors (Down/Up) 1998 / 0
CRC Errors (Down/Up) 6 / 2147480000
HEC Errors (Down/Up) nil / 0
Error Seconds (Local) 4

Also is the interleaving a normal situation, and also a desirable one?....or an automated error fixing system.

I did try to use my netgear router to connect but for some reason the primary and secondary DNS ip addresses would not save to prom..
so plugged the hub back in  doh!

Here is a speed tester you can leave running:

JDSpeedTester ver 10.8

[roseway]

CRC Errors (Down/Up) 6 / 2147480000

Don't worry about that large upstream figure, it's just a reporting error by that particular router.

[billy171]

Thanks guys for the replies, and Britbrat for the tester link.
Lo and behold, last night or should I say this morning at about 12:40, I did a final test before going to bed, and my connection flew, it may have coincided with the 3 day period for line training maybe and the con had settled down. I did a BT test and got 1850kbps! for the first time in about 4 weeks. 
Went to bed a happier bear, and got up this morning to find my wife on the laptop, who reported a flying connection of around 2megs!...that was at 07:30am this morning. She stayed on till 0900, and I got to the laptop at 09:15, did a test and got 170k on the BT tester!!
It's almost as though someone threw a switch. 
And there's nothing at home that would implicate the connection, central heating pump or the like, only the sun coming up   

I live 4.1 kilometres from SLXDS

Don't think I 'll be fine tuning mtu today

Hi Billy,

Just to be sure, you don't by any chance have an open wireless link ?

Kind regards,
Walter

Hi Billy,

Appologies for butting in as I'm not trying to distract from Walter's suggestion, but also worth thinking about...

A good connection with lousy data rates in normal hours, but much better data rates off-peak (say, midnight to 9am), can suggest the ISP may be throttling you for contravening their FUP (fair use policy).  That hardly seems likely if you've only been with them a few weeks, and in any case I'm also not sure whether an ISP's FUP throttle would show up on the BT speed tester.  Still, it may be worth checking the small print on the T&C to see if anything could explain it - especially if you're a heavy downloader (are you?).

Regardless of above, next  time you get a BT speed test - good or bad - can you let us know what  the BT tester reports for your IP Profile, as well the download speeds for the tests.

Hi Walter

No its closed alright, and my NIS firewall/ av software also reports it so...with high encryption.

And I dont subscribe to BT Fon either...doh  

I'd like some bandwidth for myself, without giving it away!

Thanks for the suggestion but , no I'm on BT Total Broadband 3 with anytime talk, so no restrictions applied, well not supposed to be...
Mostly the reason why I'm so angry at this situ as its not exactly a budget connection, and i've not had a service yet!

Hi

Your slow throughput has NOTHING to do with TRAINING period .

Your synch stats are GOOD for the attenuation on your line.

Your last synch rate Downstream 3,424 Kbps will get you a profile of 3000Kbps .  
The synch rate is the lower end of the BAND for this profile

If you want your profile to IMPROVE   Do not switch off router as your next synch may be lower .

Have you done the BT speedtest to confirm your PROFILE ?

What sort of speeds did you get during  Morning ,Evening  etc . Large differences with very low speeds during busy periods  are most probably due to ISP contention.

what was the Maximum you got ?


Regards Jeff

Hi Jeff

Thanks for the reply,
I have been informed today that my connection is under investigation by systems engineers, and as you say everything is ok so far as my line is concerned.
This also has been ratified. It appears there could be issues at the exchange, but clearly a pre-requisite for further deeper investigation warrants further time related testing, which has been initiated and is ongoing, so it's watch this space for now. Will know better in a day or two.

regards

[kitz]

Sounds like either exchange congestion or ISP throttling if you have ruled out the suggestions by others.  You should also check out your IPprofile from the BTw tester to rule this out too.

[billy171]

IP profile pans out at 2500, in line with everything else..

Have you noticed any major fluctuations in your ping times?
