Atheros AR9200 Wifi is not working

Hello,

I'm a new to hackintosh stuff and i have a Clover El Capitan installed on Asus G53SX, everything is working except my wifi Adapter (atheros ar9200).
Anyone know kext file for this adapter or should i change it to another one, if yes, so can u propose me some cheap wifi adapter.

Thank you.

I found this guy who has the same wifi adapter as me and he installed it. But i can't find how he did it.
