For analyzing wireless traffic, Wireshark users could capture traffic using AirPCap. The adapter was a USB Windows-friendly device that provided 802.11 capture support and worked well with Wireshark. 

AirPCap was compatible with several versions of Windows, from Windows 2000 through Windows 7, and many reported having successes when using AirPCap after installing the AirPCap Nx driver, which adds support for Windows 8 and Windows 10. As of writing this, the parent company, Riverbed, no longer lists AirPCap adapters or sells the devices.

Over time, OS have changed, along with wireless in general, and 802.11ac is becoming more commonplace. AirPCap has support for 802.11a/b/g/n, but does not list 802.11ac.

If you do need to capture raw 802.11 traffic, then you could use Linux, macOS, or try NPcap, a driver that will provide support for raw 802.11 packet capture.

Let's take a look at the newest packet capture engine, Npcap.
