Wireshark Windows Adapter Issue and Fix

Updated: Nov 19

I was trying to capture packets from my Network Critical SmartNA packet broker and only saw broadcast packets.


At first, I blamed the packet broker since I assumed I knew my laptop and Wireshark so well. Do you know what they say about the word 'assume'? ;)


I then set the packet broker back to factory settings and reconfigured it twice with no change. Do you know what Einstein said about insanity? He said, “Insanity is doing the same thing over and over and expecting different results.” Yup, that was me.


I then took a look at Wireshark and noticed the adapter "promiscuous" check box was not checked. When I checked the box and tried to start a capture, I got an error message saying "The capture session could be initiated". "Please turn off promiscuous mode for this device."

After some thought, I realized the last thing that changed was that I updated Wireshark/Npcap. So I uninstalled my current version of npcap, went to the npcap website, downloaded an older version and installed that one.


Now everything works just fine and i can finally move on to troubleshooting the original problem.
