 * Product page •  Datasheet

"1244-01000871-50Z" appears to be silkscreened on the board in the FCC photos.
 * The device is using two Skyworks (SiGe) SE5022T / 5022T 5GHz Power Amplifiers
 * and two Skyworks SKY85601 (SKY85601-11?) SPDT Switch w/ LNA modules.
 * The flip-up antenna (LYNWAVE ALA110-221020) is connected via an internal U.FL / IPEX connector.

Based on Edimax's provided drivers, the USB ID of the device is presumed to be 7392:a822.
 * The drivers also indicate a single-stream RTL8811AU based device
 * (USB ID: 7392:a811, AC600, EW-7811UAC?) may be released later by Edimax.


 * Warning: each time the device scans it seems to cause a 3second delay in
 * packets for several seconds (Linux 3.13 using patched 1.0.1.6 drivers).
 * As network manager does this by default every 2mins this is can be very problematic.

Review of Linux Compatibility
Edimax EW-7822UAC is a USB WiFi stick, which supports wireless connections 802.11ac.
 * The adapter bases on the Realtek RTL8812AU chipset and has the USB ID 7392:a822:

Bus 003 Device 002: ID 7392:a822 Edimax Technology Co., Ltd Until now no driver for the EW-7822UAC is included in the standard Linux kernel.
 * However, Edimax provides a Linux driver for this adapter,
 * which has to be compiled from source per hand.

Alternatively, on can use a Open-Source Linux driver from GitHub
 * by downloading the ZIP file which is available on the linked page.

The downloaded file can be compiled by: cd Downloads/rtl8812AU_8821AU_linux-master make sudo make install sudo modprobe 8812au The compiled kernel module 8812au.ko will be used automatically for the stick after reboot.

As of March 2017, Edimax has provided a detailed tutorial for compiling the Open Source driver on higher kernel versions (e.g. above 4.1)
