How to resolve airodump’s inability to capture handshake packets?

If Airodump is unable to capture handshake packets, there may be several reasons and solutions for this issue:

1. Unable to enter monitoring mode: Please make sure that your network card supports monitoring mode and has successfully entered monitoring mode. You can use the iwconfig command to check if the network card has entered monitoring mode. If not, you can try using the airmon-ng command to enter monitoring mode.
2. The signal strength is not strong enough: make sure your device is close enough to the target wireless network and that the signal strength is strong enough. If the signal is too weak, Airodump may not be able to capture the handshake packets. Try moving your device closer to the target network.
3. If there are no active devices on the target network, Airodump will not be able to capture any handshake packets. You can try connecting a device to the target network and then re-running Airodump.
4. The target network is using a hidden SSID: If the SSID of the target network is hidden, Airodump may not be able to capture the handshake packets. You can specify the SSID of the target network using the command “airodump-ng –essid “, and then rerun Airodump.
5. Using the wrong channel: Make sure that your Airodump is using the same channel as the target network. You can specify the channel by using the command airodump-ng –channel , and then rerun Airodump.

If the above methods still fail to solve the problem, it may be due to hardware or software compatibility issues. You can try using a different wireless card or another packet capture tool to resolve the issue.
