sudo ip link set wlan0 down sudo iw dev wlan0 set type monitor sudo ip link set wlan0 up Unlike airodump-ng which requires you to filter by BSSID later, hcxdumptool lets you capture everything and filter afterward. The simplest command:
--filtermode=2 means "only accept packets from this list." | Issue | Solution | |-------|----------| | No handshakes after 10 min | Move closer. Signal strength matters. | | Hashcat won't load hash | Ensure you used -m 22000 . Old 16800 format is deprecated. | | Interface stuck in managed mode | sudo airmon-ng check kill (kills interfering processes). | | Too many hashes, all invalid | Some are M2/M3 only. Re-run hcxpcapngtool with --keep-essid . | Legal Disclaimer Do not use this on networks you do not own or have explicit written permission to test. Capturing handshakes constitutes interception of communications. Use hcxdumptool only on your own lab networks, your authorized enterprise environment, or with explicit consent from the network owner. Final Thoughts hcxdumptool is not just "another wireless tool"—it's the future of WPA/WPA2 auditing. It pairs perfectly with hashcat and removes the guesswork from traditional de-auth attacks. Next time you’re performing a wireless assessment on Kali Linux, skip airodump-ng and reach for hcxdumptool . hcxdumptool kali
