I don't know.
1. Please provide the complete output of a 'wireshark -v'.
2. What kind of adapter(s) are you using ?
3. Are you using any firewall or other software on your PC which might
somehow be interacting with your network stack.
4. What happens if you actually start a capture.
Do you see the traffic "from what was already started" ??
5. Please configure wireshark to open a console window, restart wireshark
and let us know if any error messages appear in this window
when you open the 'start capture' dialog window (and when you
start a capture).
Edit ! Preferences ! User Interface ! Open a Console Window ! Always
