    WiFi Module does not work

    Hello everybody,

    I have an ASUS ROG Crosshair VI Extreme motherboard with integrated WiFi. The Module should be a Realtek RTL8822be (looked it up on Windows because Linux does not show any information about it). It is working properly (after driver install) on Windows 10 Pro but I can't get it to work on my Linux. Meanwhile I tried a lot but noting of success. The driver DVD just states in a text file "Note: Please update to the latest Linux Kernel for motherboard chipset and components support." The latest kernel should be ("uname -r") "4.14.0-kali3-amd64", installed is ("uname -v") "#1 SMP Debian 4.14.13-1kali1 (2018-01-25)", so this should not be a problem. https://wiki.debian.org/rtl819x#rtl8821ae gives some advice to install "firmware-realtek" which actually results in "firmware-realtek is already the latest version (20170823-1)".
    My USB-WiFi-Stick with a RTL8192CU Module works without any problems and the integrated LAN controller also works perfectly fine. I thought maybe it is a problem that I installed Linux using the WiFi Stick and now the drivers are interfering somehow but I could not find anything that confirms this thesis and this would be a bit stupid if you have to switch from one adapter to another e.g. because of hardware failure.
    I am not sure what else information you need, please let me know!

    Thank you for your solutions in advance!

    Best regards

    What makes you say it doesn't work? Is there any interface when running ifconfig?

    Have you looked at the content of dmesg?

    Thanks for your response!
    ifconfig shows the following:

    You can see my Lan Port, a hamachi network and my wlan0 from the USB Stick are active but my internal card is not.

    The last 50 lines of dmesg show this:

    There is absolutely nothing about my internal WiFi Adapter.
    Interestingly inxi -Fn shows the Adapter (Card-2) but without any further specification:
    Code:
    Network:   Card-1: Intel I211 Gigabit Network Connection driver: igb
               IF: eth0 state: down mac: 10:7b:44:90:2a:c7
               Card-2: Realtek Device b822
               IF: N/A state: N/A speed: N/A duplex: N/A mac: N/A
               Card-3: Realtek RTL8192CU 802.11n WLAN Adapter
               IF: N/A state: N/A mac: N/A
    So the hardware is being detected but the sowftware seems to be missing. Since it should have come with the latest kernel I have no idea how to install or activate it now.
