Help. WiFi option not appearing - Sierra

Hi,

First time Hackintosh builder, asking for some help.

Setup:
Gigabyte GA-Z170-HD3
i3 6100 - Using HD530
TP-Link WN881ND 300mbs wireless N PCIe

I've installed Sierra and tried reinstalling. Should I have the kext IO80211family? (I don't see it inside the folder)

Can anyone help me, or point me in any certain direction to fix this?

Thank you!
