Description

Using Windows 10 Pro (version 22H2, Build 19045.5011), cannot set Monitor mode. Used a number of WiFi adapters including a Alfa AWUS1900. wlanhelper (running as administrator) reports that the adapter only supports managed mode.

Npcap 1.79 and updated drivers from Alfa.

Research direction

Start by reproducing the monitor-mode attempt with wlanhelper on Windows 10 and the listed adapters, then inspect how Npcap determines supported adapter modes. The issue names no source files or tests and does not define a clear acceptance criterion; completion would require identifying whether the limitation is in Npcap, the driver, or the adapter and documenting or correcting that finding.
