AC1200 Wireless Dual-Band USB Adapter
"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 (and it is...).
- 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 188.8.131.52 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)
