• 300 Mbps - 2SS 2.4GHz 802.11n (40MHz chan.),

• 867 Mbps - 2SS 5GHz 802.11ac (80MHz chan.) = AC1200 class

Overview

• The Ubiquiti WiFi chip appears to be a custom Qualcomm Atheros QCA9882. Ubiquiti firmware calls it “Peregrine” and says the the Vid:Pid is 168c:003c It is detected as QCA9882 (hw2.0) and supported by the ath10k driver. Ubiquiti U-AME-G1-BR4A - Qualcomm Atheros QCA9882 (Peregrine)

ath79: add support for Ubiquiti airCube AC The Ubiquiti Network airCube AC is a cube shaped device supporting 2.4 GHz and 5 GHz with internal 2x2 MIMO antennas. It can be powered with either one of: - 24v power supply with 3.0mm x 1.0mm barrel - 24v passive PoE on first LAN port There are four 10/100/1000 Mbps ports (1 * WAN + 3 * LAN). First LAN port have optional PoE passthrough to the WAN port. SoC: Qualcomm / Atheros AR9342 RAM: 64 MB DDR2 Flash: 16 MB SPI NOR Ethernet: 4x 10/100/1000 Mbps (1 WAN + 3 LAN) LEDS: 1x via a SPI controller (not yet supported) Buttons: 1x Reset Serial: 1x (only RX and TX); 115200 baud, 8N1 Missing features: - LED control is not supported Physical to internal switch port mapping: - physical port #1 (poe in) = switchport 2 - physical port #2 = switchport 3 - physical port #3 = switchport 5 - physical port #4 (wan/poe out) = switchport 4 Factory update is tested and is the same as for Ubiquiti AirCube ISP hence the shared configuration between that devices.
