I've been working on this, tutorial after tutorial for hours, to no avail. I honestly don't know what else I can do.

After installing the IO80211Family.kext file via Kext-Droplet, I finally got the WIFI symbol but when you click on it, "Wi-Fi: No hardware installed". The WIFI model name is AR5B225. I've also tried installing the AirPortAtheros40.kext file separately, as it helped someone else out in forum I believe... If anyone could help me out, it would be greatly appreciated. Oh yeah, and audio isn't working either.
 
WiFi - Try the kext attached in this post from the network forum - https://www.tonymacx86.com/threads/ar5b225-ar9485-kext.287655/

Audio - Your laptop uses the IDT 92HD87 High Definition Audio Codec, which is supported by injecting Lilu.kext & AppleALC.kext from your /CLOVER/kexts/Other folder. See the screenshot below for details of which layout id you would need to use in your config.plist.
