Speed Question

[Rik]

Nice county. I wonder whether it's possible that there's been water getting into a cable joint. Keep a note of what the weather has been like immediately before another loss of speed (if there is one).

[Wobbly]

OK, (its chucking it down now, very christmassy)

stats dont look any better, even though its working ok

[Rik]

That graph range is typically Netgear, but the frequency of the noise pulses is not. You seem to get a pulse about every two minutes, which is not normal. Once you have the new extension installed, and can test at the master socket, the resultant graphs will tell us a lot more.

Those noise spikes, though, would be enough to affect your throughout, as there will be a lot of packet re-transmissions during the burst.

Response from simon at IDNet

I have run a line check on your service and it is has shown that you are suffering from errors which are probably caused by your line running too fast. It will probably prove to be more stable if we ask BT to increase the noise margin on your line. However, this will decrease the speed at which it can operate. But then stability is usually preferable to a fast and flaky service. Please can you
continue to monitor the situation and if it does not improve please contact when our office is open again next week and we'll take it up with BT for you?

Still waiting for my better extension and a cat5 to come so I can so if the extension has any affect, but the speeds a still all over the place with no pattern - 1 minute its 6 meg, the next.......



Test1 comprises of Best Effort Test:  -provides background information.
    IP profile for your line is - 6500 kbps
    DSL connection rate: 448 kbps(UP-STREAM)  8128 kbps(DOWN-STREAM)
    Actual IP throughput achieved during the test was - 81 kbps

That's pretty typical of a noisy line, Wobbly. I had my margin increased from 6 to 9db to improve stability and now I rarely get a drop, and speed is pretty much constant at ~2400k on a 2500k profile.

Sadly, there is always this speed/stability trade off with ADSL. Sort your extension out and see what happens. If things still don't improve, then I would agree with Simon's view myself.

Well my cables came



1) is with the old cheapo extension, 2) is with the proper extension, 3) is with router in master socket and long cat5 back to computer, and 4) is back to the proper extension.

Unfortunately the cat5 I bought wasnt quite long enough  so it was a shopping line  so I had to abandon that as my grandson was running around and he would probably have wrecked the lot or garotted himself

anyway, noise margin has improved, up a bit and not bouncing around as much. will see how things go then speak to ID when they are open to reduce the speed a tad

Incidentally I "helped" a guy on the Pipex (my old ISP) ADSLGuide forum who was complaining of speed, found out he had a cheapo extension and told him to plug his router into the socket direct and it sorted his problem. A week a go this was all mumbo jumbo, but I'm learning thanks to you chaps - many thanks

Hi Wobbly

That's an excellent demonstration of just how much noise a poor-quality extension can introduce, thanks for posting it. It looks like you can probably get away with the good extension, if you prefer it that way to having the router at the socket.

Keep us posted.

Incidentally, I know just what you mean about picking up the tricks of the trade, when I first went onto ADSL, I hung around forums reading everything I could. After a while, I found I could answer questions for others. We're all on the same road, just at different points along it.

can i jump in post my stats? hope wobbly doesn't mind? I just wanted to know if they were ok?

thanks guys.

Let's put it this way, I'd kill for them.

You've got the highest sync possible with some noise margin in hand (an extra 6db). Your line should be consistently fast and very stable.

[Wobbly]

pfft    (wont stay like that though)

[Rik]

Just shows you how reliable speed testers are, Wobbly. There's one I have used which consistently gives me 200k over my profile. I wish.

Mine went over the 7000 mark for the first time ever, must be a glitch in their system...

[Rik]

It's when it goes above 8000 you know you're dreaming, In. Mind you, when ADSL2 launches for you (with 21CN), you should see some incredible speeds.

[Inactive]

My speeds still show up faster than any other provider at DSL Zone, on a like for like basis.. 

I just go there to rub it in..

Spread the gospel, In.
