Trouble installing header files/network drivers

I'm trying to get a wireless card to work with Kali Linux, but I'm having a lot of trouble. I have two network cards that I can use an Asus PCE-AC56u and a Netgear WNDA3100, neither are officially supported, but I found drivers for the Asus card: https://github.com/astsam/rtl8812au/. The problem is, that in order to compile those drivers it says I need to download linux header files, but I unfortunately don't have any way to get a wired connection.....so I need to download the header files manually and copy them over via USB. I tried to download the header files from: http://http.kali.org/kali/pool/main/l/linux/ but I keep ending up in a dependency circle (e.g. XXX can't be installed because you need YYYY).

TL;DR I'm running a Kali Linux live USB version 2016.2 64 bit and need help installing header files/dependencies (and network drivers).

Downloading them is not the way to go.

Use apt-cache to search for headers and apt-get to install them.
