Describe the bug
After Upgrade from Windows 10 to Windows 11 I can't capture any more in promiscuous mode. I tried it with my LAN Interface not WLAN.
I upgraded npcap from 1.70 to 1.71 and tried Wireshark 3.6.7, 3.6.8 and 4.0.0rc1
Message is:
The capture session could not be initiated on capture device "\Device\NPF_{8B94FF32-335D-443C-8A80-F51BDC825F9F}" (failed to set hardware filter to promiscuous mode: Ein an das System angeschlossenes Gerät funktioniert nicht. (31)).
To Reproduce
Steps to reproduce the behavior:
- Doubleclick on the Interface from StartScreen
- Otherwise go to Capture Options.
- Than check the promiscous mode
- last click on start.
Expected behavior
A working capture. ;-)
