I first downloaded the latest version of Wireshark and it was working for about a week until the No Interface conflict start happening. I decided to uninstall the latest version download an old working model 3.0.13. It worked for a while like the first time I downloaded, but once again I opened Wireshark today and the same No Interface conflict happens again. I tried restarting my computer, reinstalling the software, and even downloaded WinPcap to see if that caused any issues. Problem is still not fixed and I am not sure what to do anymore. Any help would be much appreciative (p.s I also ran Wireshark as admin too and that didn't help either).

  • A previous question with some things to look at.
    • What is output of sc query npcap
    • npcap 1.00 is available (uninstall old version then install new)
    • Create a npcap DiagReport
      (For npcap 1.00, I had to modify DiagReport.bat to run the "No Exit" line)

Windows driverquery - alternative to sc query

C:\Users\admin\Documents\Wireshark\ask_wireshark>driverquery | findstr /I npcap

Have you reported that as an Npcap issue?

I would ask what else has changed, npcap isn't likely to stop working for no cause?

Unless you do not value the host machine, do NOT run Wireshark as admin, it contains hundreds of thousands of lines of code that may react badly to malicious traffic.

Spending an afternoon diagnosing powershell - ugh. Npcap issue #238
