I have been noticing recently, I put the router on in the morning, by about 7pm, the SNR is in funny figures. congestion thing or something?

Yes, found it on page 13..........you have been switching it off.

It's not necessarily the cause but I'll let the more learned members on here comment how much you've contributed to your own problem.

Thanks for the reply, but bare in mind I am on Tiscali's LLU Platform and they have their own Profiling system and not one like BTs.

If I remember from my other thread. Kitz mentioned that Tiscali don't use bRAS profiling like BT and they just have standard profiles.

If anyone thinks otherwise do mention it, however I was having no probs when on Datastream and turning the router off every night.

[kitz]

>> Is it better for the line if I leave the router constantly plugged in and never turned off, to see how it settles overnight? So that it can drop out itself etc?

I suggest you leave the router to sync/resync as it wants to for a few days, that way it'll find its own sync it's comfortable with.

As chris suggested in his post the other day I would leave it for a while and see if its able to settle at its own level.

>> Tiscali don't use bRAS profiling like BT and they just have standard profiles.

They dont have bRAS profiling, but they do have a DLM which manages their profiles.

Well, I left it on last night and it lost sync about every 20minutes.

Also I had to resync this morning to get on the web, even though it was connected, it wouldn't go to any webpages?

Had lots of these entries in the Router Logs? What is a System Call Error then?

[kitz]

Not sure - but PPP is usually the ISP bit... before that there was a device or resource busy message.
Possibly problems logging into your ISP or a router config problem.

>> even though it was connected, it wouldn't go to any webpages?

Sounds like you just have sync and not proper ISP access (PPP session)

Or alternatively I cant remember what router you use, but I do recall you recently updating your firmware... but someone experiencing similar disconnects after updating their dlink dsl504t

Here is the email from today:-

I would like to tell you that the 2nd level engineers have reset the profile for your account and they are monitoring the connection for 48 hours. I assure you that you will receive a callback within next 24 hours in order to check the speed which you are getting. I request you to wait till the 2nd level engineers contacts you.

I hope the above information will help you. Please feel free to contact us if you have any further issues. We will be happy to help you.

I am still on a fixed 4meg profile so they must have either imagined it or not done it yet, will keep you updated this morning.

Question on the ring-wire, I have a star wired system in my house and I had only disconnected the ring-wire from the master, but on reading your site, I have now done it on all of the other sockets in my house, 4 to be exact, did have five but it was a cheepo and have disconnected as I don't use it much:)

As you can see, Upstream is 448kbps

Kitz, with their DLM, if I leave the router on, is it possible that DLM will change some settings around?

Edit: Just resynced as I changed WiFi settings and Target SNR has gone down to 9dB and Sync is up to 5728kbps. Is it good that the Target SNR is down?

Looks like DLM has moved me to this profile:-

[jid]

Just came in to find the SNR in funny figures! I guess I will leave it plugged in all of the time now and not resync if necessary?

With this DLM, is it always running with Tiscali connections? How does it work?

Does it actually resync my line automatically if it feels I can sync higher, I don't really understand?

Cheers

Thing is, I will be doing GCSEs next year and wanted an easier router than changing ISP, with all the work I will have, do you seriously think I have time to go around webpages changing email addresses and sending upto 300 people notifications?

In all honesty, you could have changed ISPs and sent your 300 notifications and got on with your studies in less time than this thread has been running.

You have had several replies stating the blindingly obvious but you still carry on posting hoping that some fairy godmother will appear and wave her magic wand at Tiscalli and make them sort out your problems.

You started off this thread over 3 months ago with the title No Connection. As you now have a connection even if it is not what you want, either put up with it or change ISP. Then, perhaps you can concentate on your GCSE studies and we can concentrate on helping people with genuine problems.

They have just rung and I am back on an adaptive profile!!!! Stats are below:-

Well that has always been the case.

Max DSL (BT or LLU) is rate adaptive by default and is very rarely set at a fixed rate manually by the ISP (unless to provide a certain fixed speed using DSL Max exchange equipment hardware).

Often a certain sync speed is maintained either by not rebooting/resycning the router and the line conditions at the time of sync noise margin vs. target noise margin. If you have consistent resyncs/lose of sync the target margin is raised and can sometimes remain so (which looks to be the case with your stats of 4096Kbps with 17dB margin).

If the ISP resets the profile, it will be trying afresh from the default target SNRM compared to the one decided over time by DLM and so a sync speed increase can be expected.

If you leave the router on, it will continue to adapt to changing line conditions and so if the SNR drops too low may resync. After a few resyncs this may lead to an increase in SNR margin and hence lower speeds.

If you only use the router when the SNR is at its best, it is likely to retain the 9dB margin and provide a higher sync speed. However, the DLM may think the router being disconnected is due to signal failure and may tamper with the settings as a result.

Overall its best left as it is, leave the router on, it is set to a target 9dB noise margin which will only change if you have major sync loses.

If I were you I would now be content. The line has had its profile reset and is a decent speed anyhow. If your satisfied with your ISP, then you can save sending out 300 change of e-mail address notifications and if not, then switch to an ISP with better customer service.

As for the GCSE's, I did them four years ago and still had plenty of time for other things.

[jid]

Woke up now and had resynced to a 9 dB profile with a sync of 6304kbps!!!! Highest ever.

So I am finally a happy customer knowing that the DLM is doing its job, I am just hoping it will go up now!

Once again, as posted previously, thanks to Kitz, Ezzer, roseway, mr_chris and everyone else who posted

@soms, Tiscali put my profile to a Fixed 4meg profile with a higher SNR, DLM didn't do that?

I am now staying with Tiscali, keeping my father happy that he doesn't have to pay his line rental and pay for local and national calls!

You may close/lock this thread now.

Edit: Sync is now 6400kbps!!!!!!!!

Kind Regards and Many Thanks to you all

I still believe there's an underlying fault on your line and that you will continue to see fluctuations in your speeds.. particularly in the evenings.

I personally would not accept a 4-6Mbps down and 228kbps up as being acceptable for a 31dB attenuation line.  It should sync quite happily on their  8Mbps downstream and 896kbps upstream profile.  Ive known much longer lines sync at the full 8Mbps with much less fluctuations than what you're seeing.

But since Tiscali refuse to look into the underlying problem properly, and you are content to stay with Tiscali, then to cut your looses, I think you will have to accept speeds much lower than you could get with a decent ISP who would be prepared to investigate the obvious.

I wish you all the best with Tiscali and your connection, as IMHO this thread has been yet another prime example of Tiscali's failure to resolve problems promptly and efficiently.
However, as you now appear to be happy with your connection, which is the main thing...  at your request I have closed this thread.
