This does not use the classic four-way handshake but is often more reliable.
| 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. | aircrack-ng handshake
Open a terminal and check your interface name (usually wlan0 or wlan1 ): This does not use the classic four-way handshake
: These tools should only be used on networks you own or have explicit permission to test. | | Client reconnects instantly but no handshake
