If you don't have a remote sensor, you can still do packet captures on one or more channels using external USB Wi-Fi adapters. However, because we can't use external adapters natively as we do with the Mac's built-in Wi-Fi adapter, we need EASE (External Adapter Support Environment).
This blog post will show you how to configure a Raspberry Pi 4 with an external Wi-Fi adapter to be used as a remote sensor in WiFi Explorer Pro and Airtool. We will assume you have a fresh installed Raspberry Pi 4 using Raspberry Pi OS.
Airtool 2 makes it possible to perform affordable, multi-channel captures using multiple remote sensors and Wi-Fi adapters. As each source (a sensor/interface combination) sends captured packets back, Airtool 2 automatically merges them to generate a single capture file or an aggregated live capture in Wireshark.
The WLAN Pi is a device designed for assessing, testing, and troubleshooting Wi-Fi networks. It's a small computer based on the NanoPi Neo2 board that is pre-loaded with a [...]
