Just in case it helps anyone out there, I struggled to set up DSL Stats with this router.
I ended up using the netgear debug url to enable telnet (http://192.168.0.1/setup.cgi?todo=debug), which left me with a prompt for a username which I had to enter 'root' (without quotes).
To set up DSL Stats, I used these settings:
Modem/Router model -
IP Address: - set to the IP of your router
Telnet login name: - leave blank
Telnet password - leave blank
Telnet port - 23
tick the box " Requires command to enter shell"
Shell command - root
CLI command prefix - xdslctl
with these settings it began collecting data for me. HTH and HAND :)
