I suspect using latency or timing would be a very bad way to gauge the distance as it is easily affected. Using latency for example would cause a user with interleaving to be reported with a much longer distance than a person without it, even if they were in the same area.

Hi Rik, I don't seem to be able to find any reference to attenuation or noise margins, maybe it's because I'm just an old thicko  :-[

Gramps

I have found something here,

WANCommonInterfaceConfig

LossOfLink= 1
LossOfSignal= 7

TotalBytesSent= 24363782
TotalPacketsReceived= 101790

True, and I don't suppose it's possible to decide whether interleaving is on remotely?

Nope, not unless you have access to BT data, which I doubt is possible. Even then I suspect it would require the user to supply information to find your BT profile.

The Doctor does hide its figures well, I'm afraid, Gramps. Congratulations on digging them out.

Your attenuation is 2db better than mine, your noise margin is high, which suggests to me that the line has been dropping, so the DLM software has stepped the target noise margin up to try and stabilise the line. Even so, your sync speed is appalling.

On those figures, you should certainly get a fixed-rate 1Mbps service, if you can't get stability with Max. However, with the noise problems resolved, you should be able to get to a profile of 3000kbps, throughput of around 2800kbps. The key is how to resolve the noise.

I don't think we can take you much further here. It looks like a line fault on the figures we have, but support can run tests on your line and see what is happening, while we are limited to looking at figures and trying to decide where things are going wrong. It's rather less precise I'm afraid.

One thing I ought to ask. You have two modems, you don't leave them both plugged in do you? That would be a big no no, and would certainly cause problems with the line.

Ah well, I'll just have to leave my dreams in science fiction until they become science fact. :)

Rik, I only have one modem connected at any one time depending on which PC I am using.
I would just like to thank you all for taking the time to assist me.

Rik

Hi Gramps

Just thought I'd better check as it was about the one thing left that I could think of. :(

I'm sorry we can't come up with an answer for you. Are there any industrial units near you which could be putting noise on the line through the mains?

Well the problem seems to be back. Wanted to do some late night work on a server so it didnt affect anything during peak times and i have to wait ages for sites to load. Getting weird tracerts aswell..

Is support working today?

Just for your information; the distance field on the Speedtest.net tester refers to the distance from IDNet's servers to the Speedtest.net servers. It does not, and can not, get the distance from you personally to the server.


Well Adam I beg to differ.
I would refer you to this page ............SPEEDTEST


and this is taken direct from their page..........................

Speedtest.net initially recommends a server based on what it thinks is the shortest physical distance between you and one of the servers. However, because the Internet does not operate in direct paths, this recommendation may not be ideal. To best utilize Speedtest.net, find the server that provides the fastest and most consistent results and set it as your preferred server.

...

In other words the distance shown is what the system "thinks" is your distance from the chosen server.

Out of interest Gramps, how many times a day are you turning your modems on and off?

Hi Paul,

Support won't be working today, but you could try giving a call just on the off chance that Simon or someone is in.

Hi Devonboy.
QuoteOut of interest Gramps, how many times a day are you turning your modems on and off?
I would say 3 to 5 times a day.

Rik

Careful, Gramps, Devon and Dorset have distinct cultural differences. :)

3-5 times a day won't cause problems. Do avoid forcing more than nine re-syncs an hour though, 10 is the magic number at which DLM wakes up and takes an interest...

Apologies to DorsetBoy for my mistake, another senior moment  :-[

It's OK, Gramps - we, collectively, have a lot of those round here. :)

 ;D ;D ;D

Shame you don't have a router,you could leave the connection running then.

I know they say no more than 10 synchs in an hour BUT I could not get the correct speeds when I first had Max and was switching on and off @5 times a day.I was advised to leave the router on and after 3 days my synch,profile and speeds really changed for the better.

A neighbour had the same,no way could he get above 2.5 meg,his router was on and off several times a day,since I told him to leave it on 24/7 he gets better speeds than I do ::)

I wonder just how suitable a modem is when using MAX broadband, aside  from the lack of security you have so little control .

Gramps,if you can't get/borrow a router, could you leave your PC running for a few days to see if your line comes up to a better speed?

This is becoming a joke now, speed is under 150 Kbps today.

Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 5500 kbps
    DSL connection rate: 448 kbps(UP-STREAM)  6336 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 107 kbps

I will see what support say on tuesday and see if they and BT can come up with a fix to my problems i seem to always have.

If not then i'll be thinking about migrating.

:(

Join the club, my current speed is 128 Kbps.

DorsetBoy, Thanks,I will try your suggestion and leave my PC on for a few days.

You do have a speed test which means BT will have to take action,it is well below there acceptable level.

:(

Well my problems have been ongoing since migration and they haven't done anything that fixes it for good, they do stuff that only lasts a few days.

Dare i say it, Tiscali was much more reliable  :-\

I have read back to some of your posts regarding your speed and packetlost issue. I am just wondering what your MTU is set as your don't say in any of your posts and as noone has brought it up yet that I could see.

I'm sure support must have brought it up but just wanted to double check.

psp83

I've tried 1500 and 1458..

I can't see its my end as i get a day or 2 with a great connection (after bt has done some work) then it all goes tits up again.
