Zero One Technology PAN1000W

The device almost assuredly shares the same manufacturer as the D-Link DP-311P.

The FCC test report lists the following additional models..
 * Zero One Technology PAN1000W / PA1000W
 * Elecom LD-WL11PS/P1
 * PCI (Planex) Mini PWF
 * TRENDnet TEW-PS1

The RAM is assumed to be 2MB, same as the D-Link DP-311P.
