This was predominantly answered in this threadHow do I install an ASUS USB-AC56 WiFi adapter?
Unlike the original requester the instruction provided by chili555 (sorta) works* for me, even on USB2.0 port The device shows as Realtek 802.11n NIC
The following files are found inside the driver download file. Description: Driver for ASUS USB-AC56 Type: Wireless ASUS USB-AC56 Driver 1023.6.225.2013 for Linux 1. Combine connect and disconnect button. 2. Fix use auto run could not uninstall ASUS WLAN Card.
Installed the driver I indicated in the original post from the rtl8812AU_8821AU_linux-master package (this is a revision 4.2.2 driver):
The Good news - again that install completes and sees the USB adapter and allows it to connect to my router;
The Bad news - compared to the internal adapter the measured download speed (using a browser speedtest) is only about 7Mbps vs 40Mbps (7 at best and EXTREMELY sensitive to position)

Now - I found however, that if I am in direct line of sight of the router, the speed comes up to normal - so somehow it appears there is potentially less power to the device, which is affecting its range?
The same device in the same physical location running under windows is flawless.

1) AC56 vs internal adapter performs much slower when both at same physical location removed from direct line of sight of router
Asus Ac56 Usb
2) In the same physical location, the AC56 performs much worse under Linux than Windows
=> Perhaps less power to the device in Linux which is affecting its range?
- However the download speed is really slow:I only get about 1.3 Mbps on this adapter; 20Mbs on the internal adapter; I get over 50 Mbps in Windows. i.e. I know its not my ISP or my adapter itself - something is choking it in Ubuntu
Problem Statements:
- The 4.2.2 driver referenced above will successfully 'make' and install and fundamentally work; however unless within immediate close-proximity, line-of-sight to router, the performance will be severely compromised.
- The 4.2.5 driver from the Asus site, which appears from the overview may address this performance issue, will not install.
So I have a related question which may or not resolve the speed issue - how to install the Proprietary Asus driver module
The original syntax per link above showed to download that specific driver file and how to load it:
however I have since found the Asus proprietary driver for Linux off the Asus web-site: https://www.asus.com/Networking/USBAC56/#support
It seems like the latest driver listed on the Asus site might address the issue I'm seeing with the limited range with the open-source driver
Update MAC/BB/RF parameters and mechanism to improve overall performance.
But I simply CANNOT get this driver loaded.
I've tried using the install.sh file (making it executable and then executing it) and also making/installing just the driver folder itself - no joy with either method.
The install.sh file is now completing without causing the corruption problems I had originally:Below is the conclusion at the end of the install.sh execution script and lsmod shows the 8812au driver (first line after lsmod)
however when I plug in the adapter it is not activated:
After re-starting I don't initially see 8812au listed when I request lsmod;but if I plug in the the adapter, then I do.However if I physically remove it, the driver remains loaded. In this state, the Terminal will not respond to most commands (other than list) and neither software manager or upgrade drivers will load from the Menu. If I restart the system, these will all function normally before the USB adapter is inserted.
If I request modinfo 8812au I get this:

More:
I disabled my internal wireless adapter - ath9k - in case of conflicts with both running - it definitely is stopped, but still nothing on the usb adapter
Next - rfkill list
Edit: Found that the issue is, 4.2.5 will not load into 3.11 kernel;
However WILL successfully install in <3.10 - I ran it in 3.8 and it installed with no issues.
Also pleased to report that the performance issues associated with 4.2.2 appear to have been improved considerably in 4.2.5
So - PARTIALLY RESOLVED - in that the 4.2.5 driver will work in kernel <3.10
Hopefully a full fix will come with a modification to run in 3.11
Hopefully a full fix will come with a modification to run in 3.11
Now - COMPLETELY RESOLVED - great job by abperiasamy to see what the conflict was in 3.11 and modify so now we have a loadable working driver with the improved range! https://github.com/abperiasamy/rtl8812AU_8821AU_linux/issues/1

WARNING: Hi everyone, I purchased the USB Asus AC56R for Ubuntu 14.04, and installed the driver from the ASUS website, then SUDO broke!!! rendered my system useless. Please BE VERY CAREFUL and backup your system before trusting Asus drivers.
