[networking] Why doesn't wireshark detect my interface?

In Windows, with Wireshark 2.0.4, running as Administrator did not solve this for me. What did was restarting the NetGroup Packet Filter Driver (npf) service:

  1. Open a Command Prompt with administrative privileges.
  2. Execute the command sc query npf and verify if the service is running.
  3. Execute the command sc stop npf followed by the command sc start npf.
  4. Open WireShark and press F5.
