 * If the Whirlpool data is accurate, the default SSID is the wireless interface MAC address. WiGLE data shows the XX:XX:XX:XX:XX:XX pattern described in the Whirlpool data to be somewhat less common than XXXXXXXXXXXX.

This device is using an Anadigics AWL6153 Power Amplifier Module.

Flashing DD-WRT
The web interface on a Buffalo-router cannot be used the very first time to convert the Buffalo router from factory firmware to DD-WRT.

It is very easy though to bypass this on most models (see specific models below for exceptions):
 * 1) Get a TFTP utility for your OS TFTP_flash. Many operating systems include a GUI tftp tool.
 * 2) From the DD-WRT website, download dd-wrt.v24_std_generic.bin from the Brainslayer 12874 folder, or the latest SVN release.  There is a link to this folder in the peacock announcement at the top of the broadcom router forum.
 * 3) Plug your ethernet cable (not wireless!) into a LAN port on the Buffalo.
 * 4) Your IP address auto-assigned is usually 192.168.11.2, but you must manually set it to flash this time only.
 * 5) Assign the IP of 192.168.11.2 to your network adapter. In most Microsoft Windows this is Start, Control Panel, Network Connections, find the LAN connection and right-click, find TCPIP and click Properties, and set the IP to 192.168.11.2 and the Subnet to 255.255.255.0. Do not change any other settings!
 * 6) In your TFTP utility of choice, put in 192.168.11.1 for the Server, select the .bin firmware image you downloaded. No password is required for TFTP.
 * 7) Unplug the Buffalo. Get ready to start the TFTP upload.
 * 8) Plug in the Buffalo. The diag light with all the other lights may come on very quickly and go out. A few seconds later when the diag light blinks, immediately start the upload.

''The diag light flashes for awhile, the router restarts, and you are done! Don't forget now to change your LAN TCP/IP back to DHCP (Automatic).''

Misc. Notes: The TFTP procedure above is necessary for first time flashing from the factory Buffalo firmware to DD-WRT firmware. Many companies let you upload firmware directly from the user interface. Buffalo, unfortunately, encrypts their firmware, meaning their routers will accept only their encrypted firmware from the web interface.

The first time you flash, the TFTP method can be used to bypass the 'encrypted' firmware requirement. After dd-wrt is installed, the router firmware can be upgraded through the Web interface normally.

All the Broadcom routers normally enter a special mode in the first few seconds after power is applied that allows a TFTP transfer to directly program the flash ROM with new firmware. So what you do is get everything ready to go. 1. power up the router, and then 2. send the router the new firmware, quickly.

Reverting DD-WRT to OEM firmware

 * Once you flash to DD-WRT on the Buffalo WHR-G54S/WHR-HP-G54/WZR-RS-G54, you may want to flash back to the Buffalo firmware. The Buffalo Factory Revert files can be uploaded from the dd-wrt GUI to restore the factory firmware. The WHR-HP-G54 image is the German version. Once it is installed you can download the English version from Buffalo's site and install it.
 * A hidden LED behind the front panel may blink on older models. It slightly lights up the bridge icon. This LED is not used in the Buffalo firmware, but in DD-WRT it will flash on for 2 seconds, then off for 2 seconds.
