RevertingEdit

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

NotesEdit

These units not only support DD-WRT, but they ship with it from the factory. You can revert them to Buffalo's proprietary firmware if desired, though that firmware has reduced functionality. Both Buffalo's branded DD-WRT version and the standard DD-WRT distribution version have bugs that lead to crashing under high load, high connection count situations. BitTorrent is particularly problematic. I am not aware of a way to fix this through configuration options and there has been no patch by Buffalo or DD-WRT.

OpenWRT "Attitude Adjustment" V 12.09 works very well on these units and can be flashed from the DD-WRT upgrade page of the web based admin interface using the file openwrt-ar71xx-generic-whr-hp-g300n-squashfs-factory.bin.  OpenWRT works very well and even under abusive loads remains stable. I consider this the preferred firmware for the device.

These routers also have removable antennas and work quite well with enhanced antennas like D-Link's ANT24-0700

Note that all the above information is based on the hardware revision A1 version of the Buffalo WHR-HP-G300N
