When I bought this Wireless network card it wasn't working in Ubuntu 14.10 with kernel 3.16. Then I have found patched driver here on GitHub that was tested with Fedora but I wasn't able to compile it on Ubuntu so I've decided to create this repository and provide working sources for Ubuntu users. The instructions were taken from this superuser thread. There's nothing more except for the need of having ethernet connection to install build dependencies.
Reportedly 5 GHz is not working anymore with this patched driver as of 4.2.0-17-generic kernel. If you happen to know what's wrong or where I can find a patch for that, let me know and I'll gladly update the repo providing all the instructions so that all of us can get it to work.
Simply clone the repository, install build dependencies, compile sources, install compiled module and use modprobe to activate it.
$ sudo apt-get update
$ sudo apt-get upgrade -y
$ sudo apt-get install build-essential linux-headers-generic linux-headers-$(uname -r) -y
$ cd ~
$ git clone https://github.com/mareksuscak/asus-pce-n53-linux.git
$ cd asus-pce-n53-linux
$ sudo make
$ sudo make install
$ sudo modprobe rt5592sta
If everything worked well you should be able to connect to the Wireless network now.
Some users have had success compiling this driver after making minor changes to the source code which normally result in a compile error.
