Hardware

Chipset: TP-Link TL-WN722N v2/v3 [Realtek RTL8188EUS].
Check kernel version:
$ uname -r
5.8.0-kali2-amd64
Install kernel headers:
$ sudo apt install -y bc linux-headers-amd64
Build drivers from source and install:
$ sudo -i
# echo "blacklist r8188eu" >> "/etc/modprobe.d/realtek.conf"
# git clone https://github.com/aircrack-ng/rtl8188eus/tree/v5.3.9 /opt/rtl8188eus && cd /opt/rtl8188eus
# make && make install
# reboot
Test for packet injections:
$ sudo aireplay-ng -9 wlan1

Alfa AWUS036ACH AC1200

Chipset: Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN Adapter.
Install drivers with apt:
$ sudo apt update && sudo apt upgrade -y
$ sudo apt install realtek-rtl88xxau-dkms
$ sudo reboot
Or build from source and install:
$ sudo -i
# git clone https://github.com/aircrack-ng/rtl8812au /opt/rtl8812au && cd /opt/rtl8812au
# ./dkms-install.sh
# reboot
Test for packet injections:
$ sudo aireplay-ng -9 wlan1

Install stuff:
$ sudo apt install lshw cowpatty -y
Make sure lsusb can see the wireless adapters (it would show the chipset):
$ lsusb
Bus 001 Device 003: ID 2357:010c TP-Link TL-WN722N v2/v3 [Realtek RTL8188EUS]
Bus 001 Device 010: ID 0bda:8812 Realtek Semiconductor Corp. RTL8812AU 802.11a/b/g/n/ac 2T2R DB WLAN Adapter
Make sure iwconfig can see the wireless adapter:
$ ifconfig
$ iwconfig
$ iw dev
Turn on monitor mode manually:
$ sudo ip link set wlan1 down
$ sudo iwconfig wlan1 mode monitor
$ sudo ip link set wlan1 up
$ iwconfig
Undo:
$ sudo ip link set wlan1 down
$ sudo iwconfig wlan1 mode managed
$ sudo ip link set wlan1 up
$ iwconfig
Or create a separate virtual interface in monitor mode:
$ sudo ip link set wlan1 down
$ sudo iw dev wlan1 interface add wlan1mon type monitor
$ sudo ip link set wlan1 up
$ sudo service NetworkManager restart
$ iwconfig
Undo:
$ sudo ip link set wlan1 down
$ sudo iw dev wlan1mon del
$ sudo ip link set wlan1 up
$ iwconfig
Or do it with airmon-ng:
$ sudo airmon-ng start wlan1
In fact, that does not need to be done as airodump-ng can put the wireless card into monitor mode automatically:
$ sudo airodump wlan1
Make sure, you're not using the default MAC:
$ macchanger -s wlan1
Restart NM when there are troubles with Internet connection:
$ sudo service NetworkManager restart
