At home I have a couple of Ubiquiti access points running for my wireless access. Out of curiosity I wanted to try and see if I can crack the password. For this we need Kali Linux and a hardware WiFi dongle that supports monitor mode. Unfortunately TP-Link decided to change the chip in the v3 version of the TL-WN722N that doesn’t support monitor mode out of the box. I came accross a method to enable monitor mode on the v3.
Installing the correct drivers for monitoring mode
First we need to remove the current drivers, clone the modified drivers from GitHub and make sure the correct drivers are loaded on bootup.
sudo apt update sudo apt install bc sudo rmmod r8188eu.ko git clone https://github.com/aircrack-ng/rtl8188eus cd rtl8188eus sudo -i echo "blacklist r8188eu" > "/etc/modprobe.d/realtek.conf" exit make sudo make install sudo modprobe 8188eu
Checking monitor mode
After the correct drivers are installed we can enable monitor mode and check the status.
ifconfig wlan0 down airmon-ng check kill iwconfig wlan0 mode monitor ifconfig wlan0 up iwconfig
The TP-Link TL-WN722N v3 is a great WiFi adapter for use with Kali Linux with these modified drivers. The dongle is easy to use and cheap to buy.
