867 Mbps - 2SS 5GHz 802.11ac (80MHz chan.),
300 Mbps - 2SS 2.4GHz 802.11n (40MHz chan.) = AC1200 class

Overview

The FCC photos indicate this device has a

single USB 2.0 and a single USB 3.0 port.

Default settings are per the FCC label.

Specifications

  • Product class: AC1200 (300Mbps [2.4 GHz] + 867Mbps [5 GHz])
  • Antennas: 2x external dipole antenna w/ RP-SMA connector
  • Ports: USB: 1x USB 2.0, 1x USB 3.0
Ethernet: 1x WAN, 4x LAN (10/100/1000 Base-T)
  • Power Supply:
AC Input: 110~240V (50~60Hz)
DC Output: 12V with max. 2A current
  • Vendor firmware operation modes:
wireless router, access point, media bridge
  • Vendor firmware features:
AiCloud, USB file / printer / scanner sharing [1],
ASUSWRT interface, Smart QoS (StreamBoost?)
  • ASUS's product page also notes this product has 'AiRadar' support
(whatever that marketing term is), yet the blurb indicates usage of a
Broadcom chipset which contradicts the FCC filing for this device.
