Re: Slow sync speed

In reply to a post by Jaxx281:
Hmmm I don't want to get caught up in forum "elitism" it's not my style, but he was clearly talking about a home user. You say relevance nil on the leased line bit that was mentioned but the relevance that Enta may supply EFM services to business users on an LLU network is NOTHING to do with ADSL to a home user or anything to do with the OP's original question, so you've contradicted yourself there.

Sometimes there is being anal just for the sake of being anal and I find it unneccessary and rude.
It is not "anal", (an unnecessary rude and derogatory term), to object to something stated as an absolute fact that was and is now confirmed to be incorrect. That can never help anyone. This response to the OP:-
In reply to a post by yarwell:
the opposite, Entanet run over BT Wholesale. They might have a bit of local LLU somewhere but if they do it's incidental.
was broadly correct and served the purpose. For b_bliss to wrongly refute that was almost certainly down to ignorance on his part of his claimed employer's portfolio, as well as not being relevant to the OP, something which seems to concern you.

The details have only been posted because of you won unnecessary and rude intervention in support of him. What dragged you out of your permanent home in "Gaming", apart from a couple of non-gaming posts in the Entanet forum, one of which was telling a reseller they didn't know their own business?

I would also point out that the only person here indulging in personal abuse is yourself.

Re: Slow sync speed


[re: RobertoS] [link to this post]
 
Just to avoid confusion (which I may have inadvertently created), my Entanet connection was a business DSL.

WRT my currently (home user) issues, PlusNet have, under duress and rather reluctantly, reset my connection profile and I'm currently going through the 10 day training period again. Its probably a worthwhile exercise as I'm using a different router to when I first signed up with Plusnet. Initially I was using a Draytek Vigor2800 router which is reported to be rather intolerant of long/noisey lines. I then experienced a 9 month spate of line problems and exchange problems before BT finally fixed all the faults. I've tried a variety of routers and the Thomson Speedtouch seems the most stable with my line.

Like everyone, I would ideally like the fastest and most reliable connection possible on my line. I'm OK with interleaving to help with this as the additional latency this introduces does not affect the applications I use.

Regards and thanks for all the help and advice.

Let us know how it goes smile. For some reason it can take a couple of days before the SNR reset/retraining happens.

Re: Slow sync speed - UPDATE


[re: RobertoS] [link to this post]
 
Hi all

Been in training period now for 5 days. Sync speed started at 2,400 and line stayed up for more than a day, now however, even though the line has a decent (9db) SNR margin, the line keeps dropping (or is it dropped deliberately at the exchange?) and syncs at a lower speed, including when the router was accidently rebooted. Is this normal for the sync speed to keep dropping despite fairy good SNR during the training period or does this indicate that I still have a line fault?

Should I power off/on the router or leave it alone during training period?

Latest stats below.

Have you any idea what time of day it loses connection? Overnight, or any time?

Do you have a fixed IP address, (static IP), or does it change every or most times you reconnect, (dynamic IP)?

Have you seen the Routerstats Lite tool? This is very useful for diagnosing your sort of problem. Scroll down this page past the full product.

Don't worry too much about the 10-day training - it isn't really tuning anything. See my explanation.

Looses sync anytime of day or night. Initially it synced at ~ 2.400 for nearly two days then dropped the connection, next sync was at ~ 2.176 for about a day etc etc. Sometimes the PPoA connection stays up so the IP address doesn't change. This is typical of what my line is like and looks to me like random noise events (REIN?) as the SNR appears steady. The longest time its ever maintained the connection is 5 days. I leave my router on 24/7. Have tried Draytek Vigor 2800, 2600, BT Business hub and Thomson Speedtouch 585v6. The Thomson has proved the most reliable.

I have used the routerstats tool - typically it'll show a more or less steady SNR, then bang the line drops.

Its pretty annoying...Last April I had a good connection, syncing at 2.048, bRAS profile of 1800, and seeing throughput at about 1600kbps according to various checkers. Then we had the trees rubbing through the line, new cables/poles, then another fault further up the lane, then an exchange fault. BTW The neighbour's line is steady at 2.176 sync, throughput at 1600kbps, he's been monitoring it for me. His line uses the same cable all the way to the exchange.

tbh I knew broadband wouldn't be great in the countryside but this has been a really frustrating experience frown(

Thanks for the replies.

I had similar but worse problems after a recent pole change. The cowboy contractors had made a complete mess of the new joints as it seems that the only tools that they had besides picks and shovels were a hammer and a pair of pliers. Some cables were apparently just loosely twisted together.
O2, my ISP didn't want to know even though they were presented with a ream of very convincing data, but luckily for me, lines to adjacent properties attached to the same pole soon failed completely and BTo fixed the lot while they were there.

Another bonus for me was that my dropwire, which was previously clipped to an incoming noisy mains, was moved. My connection has seen a vast improvement in both throughput, latency and overall stability since this was done. My router has now been continually sync'd for 24 days - It couldn't hold sync for longer than around 18 or 20 hours before.

I do feel for you but you are in a much better situation than me. This BT line drops randomly at inappropriate moments as many as 40 times a day, can almost tell the weather.
On ADSL up to two years ago with various ISP's the best i could get was IP 1250 with 63.9db att.
Spent many years hovering anything from IP250 to IP1000, it was only in the demise of Enta i could get over 1.4mg throughput. Even going LLU two years ago best achieved intitially 1.9mg but stable at 1.75mg with Att 75db.
