No monitor mode option to checkbox in Wireshark (windows 10) surface go.

I installed npcap many times and uninstalled etc. no monitor mode option tho

I upgraded from an earlier version of Wireshark (not sure which; where monitor mode worked) to 3.6. Now monitor mode is no longer a checkbox.

I also found that wlanhelper is not able to set monitor mode.

C:\Windows\System32>wlanhelper Wi-Fi mode managed

C:\Windows\System32>wlanhelper Wi-Fi mode monitor Error: SetWlanOperationMode::SetInterface error, error code = 50 (The request is not supported) Failure DiagReport-20211216-063719.txt install.log

Thanks for reporting this! What version of Npcap (or Wireshark) were you using that worked before?

[zach67385]

i am using the latest versions of all of them. it never worked for me

I am guessing that maybe this feature isn't supported on the wifi adapter based on the below. If there is a way to get it to work, please let me know how.

C:\Program Files\Npcap>netsh wlan show wirelesscapabilities | findstr monitor Network monitor mode : Not supported
