Overview

The FCC ID for this model is actually 'UQ205' (UQ2051NH is the ID printed onto the label).

The LEDs on this model are green and considerably less annoying than the ALFA Network AWUS050NH v1.

ALFA seems to indicate that there is a V2 of this device using RT3572 based on the AWUS051NH v2 product page.

This YouTube video shows the v2 board, indeed, using RT3572
