stats

[Tina]

OK i don't know all the technical jargon, but my stats have gone way down. This has been going on for a week or so now. I rebooted the router, nothing changed. I went away on wed - to last night. unplugged the router and phone line.. still no better on my return.. so i dunno.

[Rik]

Not enough info there, Tina. Can you do a BT test please:

http://test.speedtester.bt.com:50301/

And also let us know your router's downstream noise margin and attenuation.

[Tina]

Thanks Rik - don't understand the last bit.. but here are the results for the first bit

Download speedachieved during the test was - 2164 Kbps
For your connection, the acceptable range of speedsis 1000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :3020 Kbps(DOWN-STREAM), 760 Kbps(UP-STREAM)
IP Profile for your line is - 2500 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 11.15:24.25:64.6 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

The results of this test will vary depending on the way your ISP has decided to use these traffic classes.

[Rik]

Your speed is fine for your profile. What router do you have.

[Tina]

I thought it might be the router tbh It's a netgear DG834G

[Rik]

Check the instructions about halfway down the page, Tina:

http://www.kitz.co.uk/adsl/frogstats.php

Do you know the version number?

[Tina]

it's V5 I think. i did it all to the last bit but got this /bin/sh: adsl: not found. I'm on a Mac so opened terminal and did it that way

[Rik]

Did you get the figures?

[Tina]

nope just that line

[Rik]

OK, best guess I can give you is that your router has been resyncing frequently due to noise bursts, so the profile has been forced down. As you can't run routerstats, I'd suggest giving support a call/email and ask them what they can see from their end.

[Tina]

That would make sense as the conection has been dropping

[Rik]

Anything change at your end, eg new electrical equipment, change to using an immersion heater etc?

[Tina]

nope nothing

[Rik]

Talk to support, then, it's going to be hard to diagnose from here without access to our normal tools. If you have an NTE5 master socket, can you take off the faceplate and connect directly to the test socket?

[Steve]

Does this not work for version 5 ?

Sorry for hijacking the thread but I thought it would be better than making my own one.

I've also been suffering from very slow speeds for the last week or so


Download speedachieved during the test was - 306 Kbps
For your connection, the acceptable range of speedsis 1000-7150 Kbps.
Additional Information:
Your DSL Connection Rate :8128 Kbps(DOWN-STREAM), 448 Kbps(UP-STREAM)
IP Profile for your line is - 7843 Kbps
The throughput of Best Efforts (BE) classes achieved during the test is - 26.98:31.99:41.03 (SBE:NBE:PBE)
These figures represent the ratio while sententiously passing Sub BE, Normal BE and Priority BE marked traffic.

The results of this test will vary depending on the way your ISP has decided to use these traffic classes.


ADSL Link                     Downstream     Upstream
Connection Speed    8128 kbps            448 kbps
Line Attenuation            23 db            7 db
Noise Margin            9 db                    25 db

Nothing has been changed hardware wise or anything new brought into the house. I had similar speed issues roughly this time last year and it took a few weeks to be resolved. I still don't know who fixed it back then.

Any suggestions?

[Steve]

I think I'd check with support tomorrow and give them your BT speedtest results. Only other suggestions are  perhaps a failing router or a very poor wifi connection.

Tried a spare router with no improvement. I'll give support a bell tomorrow. Thanks for the help

IP Profile for your line is - 7843 Kbps

That's VERY strange, somethings not right there!. Its not a valid IP profile, 7150 is the profile for a sync of 8128 and the next one up ( if you're on ADSL2+ is 8000.

I think you need to check with support Tina to find out why BT have hamstrung your connection, they'll need your BT speedtest result.

[Tina]

I've e-mailed them and included the results. Thanks guys

[Rik]

I agree with Steve, Tina. BT have bumped your noise margin sky high, it's costing you about 3.5M or more as it stands.

[Rik]

Tried a spare router with no improvement. I'll give support a bell tomorrow. Thanks for the help

The good news is that it's outside BT's acceptable speed range, so they are obliged to investigate.

[Tina]

sorry what is noise margin? Why would BT set it up high?
