"2052500401" is silkscreened on the board in the FCC photos.

There would seem to be multiple revisions of this device. It is, for now, assumed that this entry is for the v1 iteration of this device - the unit currently sold now is the RNX-N300UBv2 (product page), though the v2 driver set would seem to be for another Realtek-based device.
