    Realtek RTL8812AU USB WiFi Issues

    I just can't get my Realtek USB WiFi adapter to work on Kali. I have read hours of forum posts but still can't resolve things. I'm hoping somebody here can help me.

    My setup:
    - MacBook Pro (Running MacOS 10.14.6 Mojave)
    - Kali running as a VM inside Virtualbox
    - Realtek Wifi adapter (
    Realtek 802.11 ac NIC [0210]). Uses RTL8812AU chipset)

    Kali version:
    root@kali:~# uname -a
    Linux kali 5.2.0-kali3-amd64 #1 SMP Debian 5.2.17-1kali1 (2019-09-27) x86_64 GNU/Linux

    Issue:
    I have virtualbox setup ok to pass the USB adapter through to Kali. The Realtek adapter is listed in USB devices:

    root@kali:~# lsusb
    Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
    Bus 001 Device 004: ID 0bda:b812 Realtek Semiconductor Corp. 802.11ac NIC
    Bus 001 Device 002: ID 80ee:0021 VirtualBox USB Tablet
    Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
    root@kali:~#


    I have installed the driver using the following commands:

    apt-get update && apt-get upgrade
    git clone https://github.com/aircrack-ng/rtl8812au
    apt-get install dkms
    cd rtl8812au
    ./dkms install.sh
    ./dkms remove.sh


    Here is the status:

    root@kali:~# dkms status
    realtek-rtl88xxau, 5.2.20.2~20190617, 5.2.0-kali3-amd64, x86_64: installed
    rtl88x2bu, 5.2.4.4: added
    virtualbox-guest, 6.0.12, 5.2.0-kali2-amd64, x86_64: installed
    virtualbox-guest, 6.0.12, 5.2.0-kali3-amd64, x86_64: installed
    root@kali:~#


    However, no wireless interface is listed:

    root@kali:~# ifconfig
    eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
    inet 10.0.2.6 netmask 255.255.255.0 broadcast 10.0.2.255

    TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0

    root@kali:~# iwconfig
    eth0 no wireless extensions.

    lo no wireless extensions.

    root@kali:~#

    I have rebooted Kali, but still no luck. Device is listed in USB devices, but no network interface.

    Any suggestions?

    Many thanks.

    Hi All, Well i managed to fix this.

    It turns out my Realtek adapter had a RTL8812BUchipset and not the advertised RTL8812AU chipset. I bought it off ebay, so i guess its my fault.

    I found the BU driver and installed it and it now appears as my wlan0 interface. I'm sharing in case this happens to anybody else.
