"EPFS202UA020" and "FS202WU-1B0" is silkscreened on the board.

A date code of 0517 (April 2005) is also on the board.

This device would seem to be a Cellvision FS-202U

(the FS-202WU [wireless capable] probably shared the same board).

This device is listed on the linux-mips ADM5120 device list.

In the absense of a DHCP server, the device will assume the IP of 192.168.0.101.

Recovery via ADM Boot[edit]

Hit the spacebar three times quickly after power-on - you can then transfer

a desired file to flash via XMODEM (Tera Term will work fine if you're
in [or have] a Windows environment to work with). [1] [2] [3]

A successful recovery should look something like the following..
