This is an 802.11b version of Asus WL-500g. It has got the same board inside, only miniPCI wireless card is different.

Wireless interface worked only in White Russian 0.9 and older for me (and only in AP mode or client mode with WEP encryption). If you want to use this device in client mode with WPA encryption, you may replace your wireless card with something better (WL-120g, Atheros CM9, etc.).

Working versions:

• Kamikaze 8.09.2 (r18961) - brcm2.4
• Backfire 10.03.1 - brcm2.4, brcm47xx(not recommended, see below)

Small bits:

• SSH is refused for 60 seconds after ping is available. You have to be patient.
• USB soundcard works on all versions.

• Everything is slower. Reply to ping after power-on is 63 seconds (for brcm2.4 it is 30 seconds). SSH connection takes 5-6 seconds instead of 1-3 seconds.
• Installing packages hangs sometimes.

Reason for having root on external drive is that you want to install more packages than fit into 1.5mb of internal memory.

• For Backfire's 10.03+ : use the extroot ability as it is easy to setup
• For rest use the “Changing mini_fo's storage directory (/jffs on external media)” [howto] Changing mini_fo's storage directory (/jffs)

To check if root is mounted from external disk, check it for space: df -h /overlay or df -h /jffs. Do not install some of important usb packages like 'kmod-usb-core' when root is on external usb. That will probably disconnect the usb with root. So reboot without usb, install packages on internal root and copy updated root to usb root afterwards.
