Top 25 WiFi Tools for Analysis, Security, and Monitoring of Wireless Networks

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

Marc Wilson

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, allowing access to a wide range of devices can also put your WiFi clients and AP's at risk.

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 Heat-mappers.
  • 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.
