The Best WiFi Tools for Analysis, Security, and Monitoring of Wireless Networks

wifi tools – sniff, analyze, troubleshoot, speed tests and more!

Marc Wilson UPDATED: January 11, 2024

People used to connect to a WiFi network only with a laptop; now, they are bringing all their WiFi-enabled gadgets into the wireless environment, including their smartphones, TVs, smartwatches, speakers, etc.

To make matters more complicated, business policies such as BYOD (Bring Your Own Device) allow users to connect freely to a network.

All of these devices slow down a network making browser speeds crawl and surfing the net or performing online tasks slow.

Not only does it slow down the network, but allowing access to a wide range of devices can also put your WiFi clients and AP's at risk.

Here is our list of the top WiFi analyzers:

  1. Site24x7 – FREE TRIAL Provides businesses with a wide range of Wi-Fi tools allowing for real-time and historical performance metrics, customizable alerts, and automated remediation. Site24x7 is highly scalable making it ideal for both small and larger network environments. Start a 30-day free trial.
  2. Paessler PRTG – FREE TRIAL WiFi bandwidth utilization monitoring, enabling detection of bandwidth caps and data overloads, and identifies top bandwidth-consuming users and devices. Download a 30-day free trial.
  3. NetAlly AirMagnet WiFi Analyzer PRO This detection and analysis tool for 802.11 systems automatically documents the presence of wireless signals and captures traffic for analysis. Available for Windows and macOS.
  4. InSSIder by MetaGeek This WiFi visualizer is available in free and paid versions with the paid plan offering more analytical features. Runs on Windows and macOS.
  5. SolarWinds WiFi Network Analyzer with NPM Equipped with proactive scanning, monitoring, and troubleshooting to help you monitor and manage large-scale wireless networks.
  6. Acrylic WiFi A WiFi identifier that creates a signal quality graph for the wireless broadcasters that it encounters, showing the signal strength of each service. Available in free and paid versions. Runs on Windows.
  7. WiFiInfoView by Nirsoft A free WiFi analyzer that is available in a long list of languages. This is a reliable and useful identifier of wireless signals that decodes their characteristics. Runs on Windows.
  8. Homedale This free wireless network stumbler has some great visualization features, including a signal strength graph and a footprint mapper. Available for Windows and macOS.
  9. NetSpot This utility scans the air for nearby APs and then tracks their signals. It can overlay signal strength and footprint on your floorplan. Available in free and paid versions for Windows and macOS.
  10. iStumbler This wireless network scanner shows a list of all the signals it spotted and the information for each is constantly updated. Runs on macOS.
  11. Tamosoft TamoGraph Site Survey This tool discovers wireless signals and lists them, showing the AP’s make and model, signal strength, and throughput rate. You can also feed it a floorplan and get a heatmap. Available for Windows and macOS.
  12. LizardSystems Wi-Fi Scanner Free for personal use, this tool spots wireless signals on 802.11 a, b, n, g, and ac. All signals within range are plotted together on one graph for comparison. Runs on Windows.

Hackers can install rogue AP's or crack your security encryption with the help of sophisticated hardware sniffers.

And if you think your wireless stays within your building, think again, you might have lots of signal leakage which allows a hacker to war-drive your network.

Knowing where your signals are, and the neighboring APs is key to keeping your network secure.

With the right site survey or stumbler tool, you can solve these issues pretty easily.

Finding why your AP's are having a bad day can be as simple as changing a channel or moving an object that creates interference.

A proper penetration tester can also help you identify where your weak security spots are, and improve them accordingly.

WiFi Tools

In this article we will be covering 25 tools which are a mix of top control and traffic analyzers, security auditors, and monitoring tools to help you narrow down issues and security flaws in your network.

Below are some of the most common characteristics/processes of the WiFi tools:

  • WiFi AnalyzerMay do any or some of the following: Scanner, Site Survey, Stumbler, Spectrum Analyzers, and WiFi Heatmapper.
  • Auditing and Security – May do any or some of the following: Scanner, Site Survey, Traffic Analysis, Packet Sniffer, and Pen Tester.
  • Monitoring and Management –  Scanner, Inventorying, Site Survey, Stumbler, Spectrum Analyzers, Heat-mappers, Traffic Analysis, Packet Sniffer, etc.

We love these tools because they provide the functionality for analyzing, securing, monitoring, and troubleshooting a WiFi network.

Some of these are free, open-source, others are inexpensive, and others might be more appropriate for the enterprise.

Now let's dig a little deeper into each tool to help you find the one that fits your needs.
