"Old" wiki about Initial flash of WL500gP v2



Thought this would be a good place for ASUS WL-500G Premium v2 specific information similar to what has been added for other router makes and models. It would probably be relevant to merge any existing and future v1 content here if anyone wishes, as the differences are relatively minor.

Details on version 1



At its heart, the ASUS WL500PV2 is your basic Broadcom-based, Wireless 802.11g router. It sports a modern veneer of white and silver colored plastic. The length and width dimensions are slightly larger than your typical Linksys router. The status lights on the front are lit with orange LEDs. It is silent, passively cooled with plenty of ventilation holes along the top and bottom surface. The orange LEDs shine through the holes, but are only noticeable in dark lighting conditions. The AC adapter is fairly slim and does not hog up multiple spots on a standard power strip.

It offers several advantages over more popular G routers like the venerable Linksys WRT54GL. The most predominant advantage is the 8MB flash and 32MB of SDRAM, allowing DD-WRT Mega builds and plenty of resources for increased IP connections, ipkg installs, JFFS2 partitions, etc. The dual USB 2.0 ports allow USB printers and storage devices to be connected, and the 240MHz BCM5354 is faster than the 200MHz BCM5352 found in the WRT54GL.

One drawback of this router is the single antenna pole. It may be the case that dual antennas is just an illusion of signal range, I cannot say for sure. Also, no overclocking support in DD-WRT as of v24 SP1 and no integrated GigE switch.

The easiest, most reliable method to flash to 3rd party firmware is to use ASUS Firmware Restoration tool that comes on the CD bundled with the product. There is no firmware size limit requiring you to flash dd-wrt mini first; you can go ahead and flash dd-wrt mega right from the start.

When flashing from 3rd party firmware to other 3rd party firmware, just use the firmware upgrade utility in the web GUI. This applies to 3rd party firmwares that include a web GUI, as not all of them do so.

The ASUS Firmware Restoration Utility comes with the CD-ROM included with the device and by default installs to

  • WinXP / Vista 32-bit C:\Program Files\ASUS\WL-500gP V2 Wireless Router Utilities\Rescue.exe
  • Vista 64-bit C:\Program Files (x86)\ASUS\WL-500gP V2 Wireless Router Utilities\Rescue.exe
To flash using the "recovery" method, do the following...
1) Unplug the router
2) Press and hold the restore switch and plug in power.
3) Keep holding the restore switch until the power light starts to blink on and off.
3a) The router is now in recovery mode
4) Change the ip settings on your computer to:
4a) IP:          192.168.1.xxx(use anything above 1, I like 100)
4b) Subnet:
4c) Gateway:
5) Run the recovery program and point it to your .bin file of choice
6) Hit the "upload" button and wait about 2 minutes.
7) Change your IP settings back to DHCP and let it get an address
8) Open a web browset and go to and have fun!

ASUS stock firmware

Of course this ASUS device works with the latest ASUS firmware. Patching to the latest ASUS firmware provides a notable improvement over earlier versions, even those shipping as of Oct 2008. The interface has undergone a cosmetic makeover and provides a straightforward GUI to easily set up shared printers, shared storage, Samba file serving with user credentials and of course typical router functionality. However, the firmware is unstable and requires a reboot every day or two as functionality seems to randomly break.


Here is a useful chart from the DD-WRT Wiki comparing the different builds. Ever wanted to know what you get in mega that you don't in std? This chart has the answers.


Micro (1.7 MB)

DD-WRT micro is not a good fit for the ASUS WL-500G Premium V1/V2 router. While it has an amazing amount of functionality for such a small firmware footprint, you lose out on the SSH server, JFFS2 file system support, ipkg, WDS and more. The embedded Linux does not even have the /proc filesystem enabled, nor is their even /bin/ls available. This makes it just about impossible to add any USB devices.


Mini (2.8 MB)

Standard, Vpn, VoIp

Standard (3.6 MB)

VPN (3.5 MB)

VOIP (3.6 MB)


Mega (6.6 MB)

Mega is the only build that includes USB support "baked in", although there are non-Mega builds that also include USB support, such as the Eko v24 NEWD mini USB firmware. Which, as you can probably guess by the name, is a mini firmware image with the USB functionality built in. It is also possible to configure USB support on any non-micro v24 (and later) DD-WRT firmware release as long as the proper USB drivers are loaded.


Accepts latest Tomato firmware, but no USB support is officially possible. I have never tested it, but apparently it is possible to add USB support to Tomato.


OpenWRT page for this router


FreeWRT is the basis for other popular firmware distributons. There is no web GUI, only ssh/telnet access for management. It is not easy to upgrade from FreeWRT to other firmware. If anyone has a good guide on how to do this, please add it here because I still haven't figured it out :)
