Capturing packet traces from your iOS device
You can capture packet traces from your iPhone, iPad, or iPod touch using Airtool 2. A packet trace capture from an iOS device records traffic at the network layer [...]
Using a Raspberry Pi 4 as a remote sensor for WiFi Explorer Pro and Airtool
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.
What’s going on, Apple? – Part 2
For years, packet capturing in the Mac using the built-in Wi-Fi adapter has always worked reliably out of the box, and it is one of the main reasons many Wi-Fi professionals love their Macs to do their jobs. Unfortunately, packet capturing is now broken in the new M1 Mac.
Multi-channel captures in Airtool 2
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.
A practical introduction to Dynamic Frequency Selection
Have you ever wondered why certain channels in the 5 GHz band, more specifically in the 5.25-5.35 GHz (UNII-2) and 5.47-5.725 GHz (UNII-2e) frequency bands are (almost) never in [...]
Post processing captures in Airtool with Python
For the past WLAN Professionals Conference in Phoenix, AZ (February 21-23, 2017), I collaborated with Brian Long for the development of a feature in Airtool to allow users to [...]
Understanding the scan modes in WiFi Explorer Pro
Wi-Fi scanning is one of the basic functions in a wireless network. It is the mechanism by which a client device (e.g. computer) or an application discovers the wireless [...]
Automatic data frame slicing in Airtool
Troubleshooting Wi-Fi networks at the protocol level involves the analysis of control, management, and data frames. When doing save-to-disk captures of these frames for analysis, files sizes can grow very [...]
Link-layer header types: what do I need to know?
A few weeks ago I released Airtool, a simple menubar app for OS X that allows you to easily perform 802.11 frame captures on a single or multiple channels. [...]
