Overview

  • "AUF00D-1.6" is silkscreened on the board in the FCC photos.
The same text is on the LAPAC1750's board in its' FCC photos.
  • The SoC used seems to be QCA9558 (QCA9558-AT4A).
QCA9880 is presumed to be used for the 5 GHz radio, but, as the FCC photos are not terribly illuminating, the exact P/N is unknown.

Default settings are per Linksys's manual.

The WFA certification notes the stock OS as Linux.. and seems to note the use of a v2 QCA988x radio
