I am not able capture 4 way handshake, I also tried manually disconnecting and reconnecting my device to the network in hope that airodump-ng will capture the handshake but no luck. I checked the device was successfully getting disconnected after sending deauthentication packets, and gets automatically reconnected the moment I stop sending the packets. I tried googling about this problem but couldn't find any solution. I am using Kali 2020.2 in VirtualBox. My Wifi adapter is TP-Link TL-WN722N(V3) with Realtek rtl8188eus chipset. Also one weird thing I noticed, deauthentication attacks do not work everytime, it only works roughly 1 out of 5 times and discovering networks around me take 30-40 seconds. I tried reinstalling VirtualBox and Kali Linux, still no improvement.
Commands that I am using
- airodump-ng --bssid <bssid of router> --channel <channel number> --write handshk wlan0
- aireplay-ng --deauth 32 -a <bssid of router> -c <target client> wlan0
I can see the captured packets in handshk.cap file but no handshake is being detected by aircrack-ng.
