If the target network uses WEP encryption, continue with this step.

In the terminal, enter the following command to crack the WEP key aircrack-ng -b [BSSID] -e [ESSID] -w [dictionary_file] [capture_file]

Replace [BSSID] with the BSSID of the target network, [ESSID] with the ESSID (network name) of the target network, [dictionary_file] with the path to a dictionary file, and [capture_file] with the path to the captured packets file.

Aircrack-ng will attempt to crack the WEP key using the provided dictionary file.
