Description

i am running windows 11 and tried npcap (1.71, 1.70, 1.60, 1.55, and 1.50) and with every version i tried, wireshark shows "no interfaces." when i tried using winpcap with npcap installed, i also got the "no interfaces" issue. when i completely uninstalled npcap and only had winpcap (4.1.3) installed on my device, wireshark (4.0.1) finally sees my interfaces. nmap works with winpcap with limited functionality.

Research direction

Start by reproducing the report on Windows 11 with Npcap versions 1.50 through 1.71 and Wireshark 4.0.1, then compare interface discovery with WinPcap 4.1.3. The issue is resolved when Wireshark sees the available network interfaces while Npcap is installed; the report does not name source files or tests.
