Hacking the Belkin N1 ROUTER!
How to hack the F5D8231-4 to enable BusyBox session

Hey guys,
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!

Hi there Kevin,

Thanks for the information. I went into my user.conf and found part that said "telnetd_enabled=0" and I changed it to "telnetd_enabled=1". I've uploaded this as the router configuration.

When I go to cmd and telnet 192.168.2.1, I still get "Could not open connection to the host."

Am I doing something wrong?

Any help you give would be GREATLY appreciated!

Hey Kevin,

Gaining telnet access would really make my day. Unfortunately I tried your suggestion, but didn't get a telnet entry in the saved config file to edit. Instead, I added telnet=0 to the list which produced a CRC error when I tried to load it back. What router firmware are you using?

Failed for me using F5D8231-4_WW_2.01.19 (an Australian version). I'm not sure yet how the CRC is produced or checked.
