Overview

The device is presumed to be manufactured by Cameo.

Review of the device on it186.com (decent photos)

This device appears to be using the same board (and 2T2R capable WiFi IC [AR9283]) as the Buffalo WHR-HP-G300N.. despite being a single-stream (and single antenna) device.

On the DD-WRT forums (internal shot) Buffalo WHR-HP-GN / WHR-HP-G300N on the OpenWrt Forums

Serial settings are 115200, 8, N, 1

Default login credentials and the IP is per Buffalo's manual.

The default SSID for the device appears to be the MAC address (no delimiters, upper case hex letters).

Flashing

Flashing dd-wrt

Supported by dd-wrt as of = v24 SP2 - build 13406 - 20091207

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

Reverting dd-wrt

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
