• 1300 Mbps - 3SS 5GHz 802.11ac (80MHz chan.),

• 450 Mbps - 3SS 2.4GHz 802.11n (40MHz chan.) = AC1750 class

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.

Wi-Fi Certified : WFA54828 (as of 05/28/2014)

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