why is it impossible to see physical ethernet port through router?
In the capture menu there is only "adapter for loopback traffic capture" If i start with it I see: The capture session could not be initiated on interface '\Device\NPF_Loopback' (Error opening adapter: � stato specificato un dispositivo inesistente. (433)).
If you open up "About" under the "Help" menu, in the "Running on" section of the "Wireshark" tab, what does it say about either WinPcap or Npcap, including the version number of WinPcap/Npcap?
