Issue with installing Alfa AWUS036ACH on Kali Linux 2020.3

Hi guys,

I'm back with the same issue again and really can't figure this out:


2x years ago I have been trying to make my Alpha AWUS036ACH work on Kali Linux 2018.3a, unfortunately gave up.

Now I'm back again and this time trying to make it work with Kali Linux 2020.3





What I have done is:

- fresh installation of Kali Linux 2020.3 (Dual Boot with Win10)
- edited the file "sources.list" within /etc/apt/, replaced the file content with following lines:

deb http://http.kali.org/kali kali-rolling main contrib non-free
deb-src http://http.kali.org/kali kali-rolling main contrib non-free

- from the terminal I have issued these commands:

apt-get update
apt-get upgrade -y
apt install realtek-rtl88xxau-dkms

- the driver seems to be extracted and installed correctly so rebooted the PC and connected the WiFi card to the USB port

- from the terminal I have issued this command:

root@kali:~# lsusb
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 005: ID 8087:0a2b Intel Corp.
Bus 001 Device 006: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac WLAN Adapter
Bus 001 Device 003: ID 1058:1021 Western Digital Technologies, Inc. Elements Desktop (WDBAAU)
Bus 001 Device 002: ID 413c:2501 Dell Computer Corp.
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

This shows me the USB works correctly and it sees the WiFi adapter.

- from the terminal I have issued this command:

where interface "wlan0" is the built-in wifi card.


What am I missing?
What else shall I try?
