How to use airplay with wifi dongle?

My mac's wifi adapter was broken, so I bought a wifi dongle - ASUS USB-N10.

It wasn't work until I installed the driver: http://www.wireless-driver.com/realtek-rtl8192su-adapter-macos-drivers-ver1082/

And however it seems to be a wifi assistant to help me using my wifi dongle more than a simple driver, and my mac recognize the wifi dongle as a lan connection, so I just cannot use airplay anymore!

The question is: how can I make my mac recognize the wifi dongle correctly (as a wifi)?
