| Error | Likely Cause | Solution | |-------|--------------|----------| | No handshake captured after deauth | Client is on a different channel or 5GHz | Ensure your adapter supports 5GHz; use airodump-ng to confirm client channel. | | "No valid WPA handshake found" | Capture incomplete or corrupted | Run wpaclean clean.cap original.cap to remove junk. | | Client reconnects instantly but no handshake | Router uses 802.11w (Protected Management Frames) | Deauth won't work. Wait for natural handshake or use PMKID attack. | | Aircrack-ng runs but finds nothing | Weak wordlist | Use hashcat with rules or a larger wordlist. | | "Interface not in monitor mode" | Driver issue or interface down | Run sudo airmon-ng check kill and sudo ip link set wlan0 up before starting. |
Now, create a monitor mode interface:
: Aircrack-ng combines the SSID and each password in the wordlist to generate a hash. It then compares this hash to the one found in the captured handshake. If they match, the password is recovered. Mitigation and Best Practices aircrack-ng handshake

By capturing these four packets, an auditor can perform a or brute-force attack locally. Because the actual "cracking" happens on your own hardware, the Wi-Fi network won't even know it's being tested. Prerequisites for Handshake Capture To follow this guide, you need a specific environment: | Error | Likely Cause | Solution |
This does not use the classic four-way handshake but is often more reliable.
In the realm of wireless security auditing, capturing a is the "Golden Ticket." It is the essential piece of data that allows security professionals to test the strength of a Wi-Fi password offline. Wait for natural handshake or use PMKID attack
