With all interfaces shown, my Wireshark installation is only showing a loopback interface and three USB capture interfaces. I just completely uninstalled and reinstalled Wireshark, along with the capturing software (USBPcap, NPcap, WinPcap). Why can I not see my Ethernet and Wireless network interfaces? My real physical interfaces appear to be missing. I have already tried running the application elevated with no change.

Are both npcap and winpcap loaded ?
Can you update with the output of Help -> About Wireshark.

Please remove one of npcap or WinPcap, your preference, Wireshark will work with either but will use npcap if it's found. There is no advantage from having both.

This question is another instance of missing interfaces on Windows, there are a few similar questions here on Ask that a search will find.

The TL;DR answer is manually uninstall BOTH npcap and WinPcap, reboot and then install the latest npcap.
