If the target network uses WPA/WPA2-PSK encryption, continue with this step.

In the terminal, enter the following command to crack the WPA/WPA2-PSK key reaver -i [wireless interface] -b [BSSID] -c [channel] -vv

Replace [wireless interface] with the name of your wireless network interface, [BSSID] with the BSSID of the target network, and [channel] with the channel number of the target network.

Reaver will initiate the WPS (Wi-Fi Protected Setup) attack to crack the WPA/WPA2-PSK key.
