Wireshark on Win11 can't capture local UDP traffic on Mobile hotspot

Open xenkuo opened this issue 2 years ago • 0 comments

Describe the bug On Win11, I created a mobile hotspot to share WIFI internet. Two devices connect to the hotspot and try local UDP communication. The communication is ok and the traffic packets can be captured by Microsoft Network Monitor, but Wireshark can't capture it.

Seems like other traffics like TCP, broadcast UDP packets can be captured and Win10 doesn't have this issue.

To Reproduce Steps to reproduce the behavior:

  1. Setup Mobile hotspot on Win11.
  2. Setup two devices connect to the hotspot and do local UDP communication.
  3. Setup Wireshark to capture the traffic.

Expected behavior Wireshark could capture the local UDP traffic.
