The problem of capturing WiFi wireless network packets

[blueboy727]

1. Wireless network cards must be connected to the network in order to capture packets. Can wireless network cards capture packets when not connected to the network? I can use Wireshark to capture packets when the network card is not connected.

2. Unable to capture probe request or beacon frame packets, only packets from other protocols can be captured. The protocol data captured using Wireshark is complete.

My local environment: win11 + NPCAP (1.78) + pcap4j (2.0.0-alpha.6)

Please help me, thank you
