Could anyone write a small program to log the Signal-to-Noise figures 
for a Netgear DG834 router?

I have been getting very variable SNR readings - and I would like to 
collect some evidence to analyse.

What is needed is a program that logs into the router's html page every 
minute, and then extracts the time and the SNR figure, and writes a line 
of a text file.

I reckon it would be useful to many people.
