Per LOM

Set your pc to static ip 192.168.11.2, netmask 255.255.255.0, gateway 192.168.11.1

open a cmd window and type arp -s 192.168.11.1 ro:ut:er:ma:c

open your tftp program, enter filename, destination ip and set retries to 100. Don't start the tftp transfer yet.

(Destination is the router at 192.168.11.1)

Power on the router, wait 5 seconds and then start the tftp transfer at the pc. It will normally take another 5-10 seconds before the transfer starts.

The above works for WHR-HP-G300N which is basically the same router as WHR-HP-GN
