I'm assuming you're using a Buffalo WHR-G300N router and using the TFTP method. Although you can use these tutorials for any Buffalo router using the same method. If you're using TFTP to flash DD-WRT firmware on a non Buffalo router, you may need to change some of the IP Addresses (some use the range 192.168.1.1 - 192.168.1.XX as opposed to the Buffalo 192.168.11.1 range).

If you'd like more help, or a little unsure, check out the Beginners Guide.
