See more details about this feature in section For software that use Npcap raw 802.11 feature. Meantime, Npcap also provides the WlanHelper.exe tool to help you switch to Monitor Mode on your own. Npcap directly supports to use Wireshark to capture in Monitor Mode. When your adapter is in Managed Mode, Npcap will only supply Ethernet packets. When your adapter is in Monitor Mode, Npcap will supply all 802.11 data + control + management packets with radiotap headers. You need to select the Support raw 802.11 traffic (and monitor mode) for wireless adapters option in the installation wizard to enable this feature. Raw 802.11 Packet Capture: Npcap is able to see 802.11 packets instead of fake Ethernet packets on ordinary wireless adapters.Npcap then does the magic of removing the packet's Ethernet header and injecting the payload into the Windows TCP/IP stack. User-level software such as Nping can just send the packets out using Npcap Loopback Adapter just like any other adapter. Loopback Packet Injection: Npcap is also able to send loopback packets using the Winsock Kernel (WSK) technique.Try it by typing in commands like ping 127.0.0.1 (IPv4) or ping ::1 (IPv6). If you are a Wireshark user, choose this adapter to capture, you will see all loopback traffic the same way as other non-loopback adapters. After installation, Npcap will create an adapter named Npcap Loopback Adapter for you. Loopback Packet Capture: Npcap is able to sniff loopback packets (transmissions between services on the same machine) by using the Windows Filtering Platform (WFP).

In this case, applications which only know about WinPcap will continue using that, while other applications can choose to use the newer and faster Npcap driver instead.

If compatability mode is not selected, Npcap is installed in a different location C:\Windows\System32\Npcap with a different service name npcap so that both drivers can coexist on the same system. WinPcap Compatibility: If you choose WinPcap Compatible Mode at install-time, Npcap will use the WinPcap-style DLL directories c:\Windows\System32 and servcie name npf, allowing software built with WinPcap in mind to transparently use Npcap instead.This is conceptually similar to UNIX, where root access is generally required to capture packets. If a non-Admin user tries to utilize Npcap through software such as Nmap or Wireshark, the user will have to pass a User Account Control (UAC) dialog to utilize the driver.
Extra Security: Npcap can be restricted so that only Administrators can sniff packets.Moreover, since Linux already has a good support for latest libpcap API, using Npcap on Windows facilitates your software to base on the same API on both Windows and Linux. The latest libpcap 1.8.0 has integrated more fascinating features and functions than the deprecated libpcap 1.0.0 shipped by WinPcap. Latest libpcap API Support: Npcap provides support for the latest libpcap API by accepting libpcap as a Git submodule.It's faster than the deprecated NDIS 5 API, which Microsoft could remove at any time. NDIS 6 Support: Npcap makes use of new NDIS 6 Light-Weight Filter (LWF) API in Windows Vista and later (the legacy driver is used on XP).It also received many helpful tests from Wireshark, libpcap and NetScanTools. It is sponsored by the Nmap Project and developed by Yang Luo under Google Summer of Code 20.

Npcap is an update of WinPcap to NDIS 6 Light-Weight Filter (LWF) technique.
