Quote from: kuja on Apr 03, 2006, 20:15:15Is SNR the same as DS Noise margin, if not how can I find out what my SNR is?

BT require a minimum SNR to allow you to sync at any given speed (I think it's 6dB). Noise margin is how much you've got in excess of that minimum.

So your SNR can go down to 6dB without worrying, that's equivalent to a noise margin of zero.

Does that help?

Can't help with finding out the actual value, I'm assuming the 6dB figure. Xbandito may well come up with something, he knows more about telnetting in to a router than I do!

Kuja, are you able to "telnet" into your router ?


Not sure m8, I have a Netgear DG834 v2..

Cheers for that m8, at the moment the DS Noise Margin is around 1-3dB, hopefully thats ok.

Well, how I telnet into my router may be different to other users...   :)

Bring command prompt up, type in   telnet 192.168.1.1  <enter>  (usually this is the ip of your router)
login and password will come up and if you have not changed them, they are admin , admin    :)
now this bit may be different on each make of router, I am not sure

get dsl params        <enter>

and you should have all imfo there  -:
local line atten(db) = 29.5
local snr margin(db) = 6.0

Kuja, you don`t need to Telnet your router, stats are already there for you ;)

However, just to see if you can, copy this http://192.168.0.1/cgi-bin/webcm?todo=debug and paste into browser, see if you get a message "Debug Enabled".

For the DG834, to enable telnet, go to http://192.168.0.1/setup.cgi?todo=debug . Which will display the message "Debug Enabled". Telnet will remain active untill the router is restarted.  ;D

1.88 Mbps (1922.9 kbps) from the IDNetters speed tester, however. (Planned for release shortly :P)

Thanks Adam, that worked.

However, I'm not getting any login prompts etc, its not accepting 'get dsl params either'

Open up a command prompt and type in at the prompt telnet 192.168.1.1 or 192.168.0.1, depending on what your router address is, there will be a prompt for password, enter it (you won`t see anything on screen) then copy this , right click beside the hash and paste:

cat /proc/avalanche/avsar_modem_stats

Very good :)

You may see a slight drop in sync speed during peak hours if your SNR drops below 6 but it shouldn`t affect throughput.

Begs the question, is anyone actually getting a throughput anywhere near their sync?

I'm getting about 650kbps -> 700kbps from http://gamefiles.blueyonder.co.uk

Not settling at a constant speed, but its spiking between the above rate :)

I'm not complaining though! :-* ;)

Same here Kuja, can`t complain at any extra speed for no extra cost! :)

Mark, BT had informed us that once a line is Maxed, it could take 75 minutes to increase throughput, but for reasons unknown this has not happened in some cases. :\

That's a Netgear router, right? There's an error in the firmware, it's not "dropping" to 0dB, it's rising from -1dB. The 2147... is a mis-representation of -1 in binary. If it's a DG834, I think the later firmware, which you can get from the Netgear site, will fix it. Amongst other things  ;D
