Linux Netgear Netgear DG834G/GT script

I have a script which I use to over-ride BT's noise margin on my Netgear router.
Paste the following lines into a file, reset_router called in your home directory:-
Quote
#!/bin/bash
wget --http-user=admin --http-password=password http://192.168.0.1/setup.cgi?todo=debug
(echo /usr/sbin/adslctl configure --snr 48 ; sleep 1.0; echo exit) | telnet 192.168.0.1
rm "setup.cgi?todo=debug"

Change the attributes to execute=yes, write=no
Run it from a command line with ./reset_router
or run it from a menu option (no special authority required)
You may need to massage it a bit:-
admin=your router signon admin name
password=your router admin password
48 is a value that gives me a 6dB noise margin - use higher values for higher noise margins.
Well it works for me anyway... Grin

Are you sure it works on an 834G as that uses a different chipset and firmware load to the GT and I have not seen any other script that allows SNR to be changed on the G.

Re: Linux Netgear Netgear DG834G/GT script

Can't swear to the 834G - I thought I'd seen it (somewhere) - but anything with a telnet interface that supports the
/usr/sbin/adslctl configure --snr NN
command should work though.
http://www.kitz.co.uk/routers/netgeardg834_interleaving.htm seems to indicate that the adslctl command is enabled (at least in some form).

Would it be possible to use something like this in Mac OSX with a DG834 v2?

Re: Linux Netgear Netgear DG834G/GT script

As I suspected it is only the 834GT/834PN range that allows the SNR figure to be changed at the router end.
The 834/834G V1/V2/V3 do not support that feature as it does not have an adslctl command. The V4 might as it uses a different chipset and has the adslctl command, but cannot confirm it.
If it were possible then The DMT tool would list that router, but it does not.

Never mind, but thanks Peter.
