D-Link DWA-171 rev A1

Wikidevi Notes
"Ver:A0-0'13/01/10" (or something like that) and "Made in China" is silkscreened on the board in the FCC photos.

This device would appear to have been listed in a MediaTek driver set with a 2001:3d02 (USB\VID_2001&PID_3D02) USB ID. I suppose this adapter was orignally slated to use MT7610U.
 * A Cameo manufactured RTL8821AU device in Realtek's vendor driver set for the 8812au has a USB ID of 2001:3314..
