Best WiFi Analyzers for Linux

Kismet works with Wi-Fi interfaces, Bluetooth interfaces, some SDR (software defined radio) hardware like the RTLSDR, and other specialized capture hardware. Kismet works on Linux, OSX, and, to a degree, Windows 10 under the WSL framework. On Linux it works with most Wi-Fi cards, Bluetooth interfaces, and other hardware devices. On OSX it works with the built-in Wi-Fi interfaces, and on Windows 10 it will work with remote captures. There are several ways you can help support Kismet development financially if you’d like to; support is always appreciated but never required. Kismet is, and always will be, open source. With the new Kismet codebase (Kismet-2018-Beta1 and newer), Kismet supports plugins which extend the WebUI functionality via Javascript and browser-side enhancements, as well as the more traditional Kismet plugin architecture of C++ plugins which can extend the server functionality at a low level.

Sparrow-wifi has been built from the ground up to be the next generation 2.4 GHz and 5 GHz Wifi spectral awareness tool. At its most basic it provides a more comprehensive GUI-based replacement for tools like inSSIDer and linssid that runs specifically on linux. In its most comprehensive use cases, sparrow-wifi integrates wifi, software-defined radio (hackrf), advanced bluetooth tools (traditional and Ubertooth), traditional GPS (via gpsd), and drone/rover GPS via mavlink in one solution. Wifi source hunt - Switch from normal to hunt mode to get multiple samples per second and use the telemetry windows to track a wifi source. Bluetooth identification - LE advertisement listening with standard bluetooth, full promiscuous mode in LE and classic bluetooth with Ubertooth.

wavemon is a wireless device monitoring application that allows you to watch signal and noise levels, packet statistics, device configuration and network parameters of your wireless network hardware. It should work (though with varying features) with all devices supported by the Linux kernel.
