For fixing incompatibility with old versions, make sure to install Wireshark and NPcap versions that are compatible with your OS. Issues arise if you have older/incorrectly installed/non-traditional versions of one of those or if Npcap got installed incorrectly.

If you have new PC, OS, Wireshark + Npcap versions, you should do fine. If you go with Wireshark installation without Npcap, you can install it separately later. This is the same Npcap installer that you get from the Npcap’s download page. If ticked, the Wireshark installer will copy and call the Npcap installer, so you get the installation done “all in one place”. The installation of Npcap is included as an installation option in the form of a box that you can tick or untick. In Wireshark installer from 3.0 onwards, WinCap is replaced with Npcap. This error means that for some reason, Wireshark failed to find any networks – and usually because something is wrong with your WinCap/Npcap. These adapters perform initial scanning of the host PC for network connections.īut if in the scanning process resulted in Wireshark not finding any networks, you get the nasty “ No interfaces found” message right in the place where it should show the list of available network interfaces. Normally, when you start Wireshark, it immediately finds and shows the list of all network interfaces available for traffic capture. The primary purpose of WinCap/Npcap is to monitor and capture live network traffic. predecessor is highly recommended (if not a must). Npcap replaced WinPcap inside the Wireshark installation process and using Npcap instead of its obsolete 14 y.o. Recently (Feb 2019), WinPcap has ceased development. To do its job, Wireshark runs on top of either the WinPcap or Npcap (packet capture library for Windows). What does the “ No interfaces found”error mean? Npcap replaced obsolete WinPcap in Wireshark PC/OS/Wireshark/WinCap version incompatibility.Npcap not installed/installed incorrectly/without root.You have the WinCap adapter instead of Npcap.Why does this happen? Usually, the reason is:

Wireshark not showing any interfaces (at least, your Ethernet adapter) is a common problem many of us are annoyed with. Why is Wireshark not showing Interfaces on Windows 10? Wireshark “No interfaces Found” – Windows 10 Fix
