DG834GT Stats basic version. (This should also work in Opera and Safari)


Enable telnet          Open telnet console      to disable type "killall utelnetd" in the console. (Enable telnet should also work in Opera and Safari)


Target Noise Margin


Override Target Noise Margin % of default target margin  86%=6dB, 100%=7dB(default), 114%= 8db, 180%=12.6db... (also works in Opera)

Connection Table (ip_conntrack)



DNS Settings





Reboot the Router, or restart the PPP connection for DNS changes to take effect. If you input invalid DNS servers, you will be unable to access the internet - to restore the original setting click the "use ISP allocated Domain Name Servers (default)" button above. This change can also be cleared by resetting the router to factory settings using the reset button in the back


This page must be downloaded and opened locally for these options to be enabled.

Add entries to router's hosts file


These settings are not particularily useful unless your connection is 100% stable as the Netgear's host file & its dns server will be reset every time the PPP connection is re-established after a drop.

Enter IP address <space> hostname (eg. 192.168.0.10 mel.lan)





(doesn't survive connection drop or reboot)

Reset DNS Server


Router based "speed test"


If you think poor speeds are caused by your PC or wireless link - This will download a file to the router and time the download (if this test fails to work choose a download file with a shorter URL) Results are only a very rough estimate.

Input the URL of a file to download and its filesize (url must be quite short).

Please be patient, the page will only open once the file download has completed.

Download url Filesize=


Alternative test: Downloads and displays the start and end times so that you can calculate the speed more accurately

Download url {44668/(end-start) Kbps}

Excellent work! Have been looking for a tool to sync the router at a specific noise margin since the firmware update screwed the last tool. Many thanks!

Many thanks for this. A nice addition/ amendment would be:

For the "Target Noise Margin", not to have to 'click the "Connection Status" button, and click on Connect'. Can this be automated as in Mognuts?

With Mognuts I used to save the command (e.g. http://192.168.0.1/setup.cgi?todo=ping_test&c4_IPAddr=%26/usr/sbin/adslctl+configure+--snr+144) as a favorite and just click on that everytime I booted my router.

I made the target margin thing drop the PPP connection first because I found I often had problems reconnecting if I just resynced the router - I presume a stale PPP session (usually cured by clicking on the sky test button)

If you prefer to just resync as per your example, edit out the "rc+wan+stop;" from the URL.

http://192.168.0.01/setup.cgi?todo=ping_test&next_file=diagping.htm&c4_IPAddr=127.0.0.1>/dev/null;PATH=/usr/sbin;adslctl+configure+--snr+144+>%261+2>%261;

Mel, do you have the ability to offer a peak at the pppoa_username and password within your utility. Yes i am a UK SKY customer with a struggle to shake the DG834GT off my shoes. All threads so far leading no where.

Mel, thanks for the "knowhow" on amending my "favorite" to "Target Noise Margin" without the connect.

I'm fine, but others might like the option via the main page.

Thanks a lot for this dude. I was looking how to change my dns on this version for quite sometime.
BTW, the change DNS button is disabled, so I ve just enabled telnet and typed some commands I found on a forum..

Thanks again
