FCC ID: MSQWL500GD
CPU: Broadcom 5365
RAM: 32 MB

Software on router after

WL-500gD English Firmware
Version: 1.9.6.0

Host operation system is Fedora 19 (64 bit).
If you are not using Fedora 19, you should virtualize it:
Installing Fedora 19 (64 bit) in VirtualBox

I presume that you can communicate with your router.

Preparations

  1. Go to Asus Support site: http://support.asus.com/download/
    Type “wl-500g deluxe” in Model Name Search box
    Click Searchasus_support_search
  2. Click “WL-500g Deluxe
    found_wl500gd
  3. Select WinXP as OS
  4. Click Firmware
  5. Click “Global” in the Version 1.9.6.0 frame to download the firmware
    If it doesn’t work here is a copy of it one my site: WL500gx_1960_EN.zip
    router_page
  6. Decompress the firmware
    $ unzip WL500gx_1960_EN.zip
  7. Check firmware checksum
    $ sha1sum WL500gx_1.9.6.0_EN.trx

    It should return:
    a273a7e7c5278d4eb76c53c20492a772187ced59  WL500gx_1.9.6.0_EN.trx

Firmware update

  1. Copy this file in the router
    $ scp WL500gx_1.9.6.0_EN.trx root@192.168.1.1:/tmp/

    Note: My router IP address is 192.168.1.1, change it to your router IP address in all commands

  2. Login to your router
    $ ssh root@192.168.1.1

    Enter your password.

  3. Write the firmware to flash
    root@OpenWrt:~# mtd -r write /tmp/WL500gx_1.9.6.0_EN.trx linux

    mtd

  4. Wait until “Rebooting …” appears
    Note: If you have configured your router as an OpenFlow switch before using my guide than you have to pull out the LAN cable from WAN port now and plug into a LAN port (eg. LAN1).
  5. Go to http://192.168.1.1 in your browser
    user: admin
    password: admin

    Press Enter
