slow speeds - netgear dg834g v4 error reporting ??


[link to this post]
 
hi there my current router stats


ADSL Link Downstream Upstream
Connection Speed 4768 kbps 448 kbps
Line Attenuation 41.0 db 21.0 db
Noise Margin 7.3 db 21.0 db


about 4 hours ago we had thunder and lightening, since then my speed as been bouncing about from 0.5 to just over 1 meg , the noies margin does seems to be moving about between 6db and 9db at the moment.

i use JDs auto speed tester all the time , and today noticed when it did the ping test it keeps dropping packets

here is a ping test from command prompt ( which looks ok )

C:\Users\PC>ping www.bbc.co.uk

Approximate round trip times in milli-seconds:

when i try to do a bt speed test at the moment i get

is there a way to get more stats out of this router as i know some show errors and such like

Click on this link: http://192.168.0.1/setup.cgi?PATH=/bin:/sbin:/usr/bi... and you won't need to mess about with TELNET.

i did a disconnect through the router , then turned off then on, i see that they sync as gone down and its seems like noise has gone up by 3db.

hoping some one else can tell a little more from these current stats , many thanks

Running at half-speed and full of errors frown

Are you plugged into test socket behind faceplate? Removed ring wire? Extensions sockets and extension leads? All filtered?

what could be causing this, is it worth tying another router?. also checked the phone and the line is clear , no noise or hissing , many thanks

That's looking far better.

So long as nothing strange happens, you now need to leave things alone for 8-12 days, as the DLM has scope to lower the noise margin and so increase the connection speed. It takes 10-14 days to do that if it thinks the line will sustain it. You've already done 2 days.

It may disconnect you overnight after that time, and reconnect with 6dB and higher sync. Around 500-750kbps increase. Keep a check on stats and let us know then whether it happens or not.

Once we are past that stage, we need to look at why it doesn't then connect at more like 7Mbps, which is what is indicated by the 40dB attenuation. There is an ongoing problem, but we need to see what the DLM thinks of the stability by seeing what it does to the noise margin.

What you could do now though is download DMT v8.07, (read what I say about it on the page I gave you a link to at the start for the telnet stuff), and get that to show the bit loading graph, as in this screen shot. Upload that somewhere for us to see. That could help us diagnose the problem.

You can monitor the noise margin with that, but whatever you do do not use it to alter any settings at this stage! You could mess things up during the 8-10 days. Or in fact at any time without us telling you what to set to what smile.

Good luck.
