 * WHR-HP-GN and Buffalo branded DD-WRT 14512 is FLAKY!!!

Flashing DD-WRT
1. Connect computer via switch

PC == Switch == WHR-HP-GN

2. cmd => ping -t -w 10 192.168.11.1 3. tftp ==> browse file xxxx.tftp (download from dd-wrt website) 4. unplug the WHR-HP-GN, and then switch on the WHR-HP-GN 5. Count 1 to 9 (count the response time in cmd) and hit the button (in tftp program)

NOTE>>> You need to find the exact time to hit the button... if not success, try again with another different waiting time

Reverting from DD-WRT to OEM
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
