Currently I am running into an issue where I can't seem to find a way to identify which WiFi adapter I want to use as my primary in Kali (v 2017.1)

My laptop has a normal PCI WiFi card inside however I have a RTL8812AU USB 3.0 adapter as well. The way I know I'm using my internal is because I can only see the 2.4Ghz broadcast spectrum.

I am using the same Realtek drivers I use on my desktop which works fine, but unsure if there was an error here. It appears under lsusb. I am looking for a way to perhaps identify the adapters and choose which one to use. Should both be showing up in ifconfig under perhaps wlan0 and wlan1 or something similar?

EDIT: Output of lsusb:

  • I mean currently I only see wlan0, and the secondary under lsusb. I guess I was wondering if it should work that way, where it displays both modules as such Commented Jun 3, 2017 at 20:46

    Perhaps I need to reinstall the driver? Commented Jun 3, 2017 at 21:01
  • I have tried all of those drivers off github before, and fail to compile/install any of them (see newest edit), the only one I've had success with is the realtek-tl88xxau-dkms stated. Commented Jun 3, 2017 at 21:31

It turns out I did need to fully remove and reinstall the WiFi driver, and now both do show up when executing ifconfig as wlan0 and wlan1 respectively. As well as both appearing in the network-manager GUI (see image).

The steps I took were:

  • Uninstalling the driver by running sudo apt remove realtek-rtl88xxau-dkms followed by sudo apt autoremove

  • Installing the driver by running sudo apt install realtek-rtl88xxau-dkms

  • Unplugging and replugging the WiFi adapter in question
  • Run ifconfig to check for success, there should be an additional WiFi adapter
