Those trying to get this working under Linux can find instructions that linked to a patched version of the RTL8822BU driver which does work with these. (the driver on the cd will not compile correctly) I've tested it on ubuntu/kde-neon(16.04) but the driver is distro agnostic and should work on any version of linux. DKMS is used to have the kernel module auto get recompiled every time you upgrade the kernel so you don't have to do it manually.
Note: The led on top of the device does NOT light up and flash when device is transferring information. The chipset is also an rtl8812BU and not the rtl8812AU in the AC600 dongles. These are NOT handled in any way the same.
Since this dongle has an actual antenna port you can replace the one that comes with it with a powered one or use a "cantenna" should you need long distance connectivity.
