Note: If the wireless NIC doesn’t support monitor mode, the WireShark cannot capture full 802.11 frames (including 802.11 management, control and data frame) and the WireShark will transfer the 802.11 frame to the fake 802.3 frame which doesn’t have the head info of the 802.11 frame. Some wireless NIC with special driver can also work at monitor mode and capture wireless packets. 2) It has 3x3 radios that can sniff 3 NSS traffic. Modern MacBook is recommended because 1) its wireless NIC driver supports monitor mode. WireShark is available at It’s a free and powerful sniffing and analyzing software. This document will discuss how to capture the wireless packets by using the MacBook and WireShark.
Wireshark happens to bundle an installer for WinPcap (in older versions) or Npcap (in current versions), but that doesn't make it "fully integrated" with Wireshark - it's just bundled we aren't responsible for building WinPcap/Npcap or its installer.Packets capture and analysis are very important for us to troubleshoot when some unexpected wireless connection problems occur such as the wireless client unable to associate with the SSID, the client not obtain an IP address, or intermittent wireless connection, etc. That's not shipped as part of the OS, so it's not "fully integrated" with the OS. On Windows, you're probably using the libpcap that comes with WinPcap or Npcap. In all of those cases, it's not part of Wireshark, it's either part of the OS or something installed by whoever compiled and installed it. On other UN*Xes, the user would have to compile and install libpcap themselves - but they'd probably have to do that with Wireshark, as well. On most OSes (Linux, *BSD, macOS, Solaris 11 and later, AIX), it's usually supplied as part of the operating system, although somebody could build it from source (if they want a newer version than what's supplied with the operating system) and compile Wireshark themselves, linking with their own version. On UN*X, libpcap is usually a dynamically linked shared library. On Windows, libpcap runs atop WinPcap's or Npcap's library and driver, if you're capturing on a regular network interface it runs atop AirPcap, if you're capturing on an AirPcap adapter. On UN*X, libpcap runs atop the OS's packet capture mechanism, which is what does the work. On UN*X, Wireshark uses libpcap to do capturing, whether on Wi-Fi or non-Wi-Fi adapters on Windows, it can use WinPcap or Npcap, whether on Wi-Fi or non-Wi-Fi adapters.
What library is used by WireShark to capture Wi-Fi ? Is it Airpcap ? Npcap ? Another one ? Is it fully integrated or installed separately (like a.
