Overview

For the original filing (09/26/2003)...

"(C) 2003 Microsoft", "HW Rev A4", and "MN-740" is silkscreened on the board in the FCC photos.

The device uses engineering samples of the AR2312A (AR2312A-ES) and AR2112 (AR2112-ES)

A MAC label w/ a 00:03:2F (Global Sun Technology) OUI is affixed to the board. For the later filing (11/23/2003) and presumed production model...

"(C) 2003 Microsoft", "MN-740", and "HW Rev B2" is silkscreened on the board in the FCC photos.

The firmware on this device can apparently be changed to that of the D-Link DGL-3420 (WPA support). See here.

Notes:

- No firmware was found

- OS: Probably similar with D-Link DGL-3420
