Identify the target network you wish to assess from the list displayed by Aircrack-ng.

In the terminal, enter the following command to capture packets from the target network airodump-ng -c [channel] --bssid [BSSID] -w [output_file] [wireless interface]

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

Aircrack-ng will start capturing packets and saving them to the specified output file.
