Just found out how to enable Telnet to the belkin N1 router. Discovered that, like many other hackable routers, it runs linux... It's quite simple to enable telnet and open a busybox session:
1) Save the current configuration file (user.conf). Open it with a text editor, and search for the value "telnet". Enable this parameter. Save it, and upload it back to the router. CONGRATULATIONS! Now open up a telnet session to your router! BAM!
Within the telnet session, you can modify just about anything!
I've attempted to increase the transmit power through the iwconfig command, but got the following message:
#iwconfig ath0 txpower X
(where X is an integer). Here is what is returns:
"Warning: Driver for device ath0 has been compiled with version 19 of Wireless Extension, while this program supports up to version 17. Some things may be broken..."
Thought I'd throw this knowledge out there so you all could expand on it... Enjoy!
