InSSIDer from MetaGeek is an established WiFi analyzer tool for the Windows operating system. InSSIDer is available in three different editions: inSSIDer Office, inSSIDer Office + Wi-Spy Mini, and inSSIDer Office + Wi-Spy DBx. The most affordable editions, inSSIDer Office, doesn’t support 2.4 GHz spectrum analysis, can’t measure 2.4 GHz channel utilization, doesn't support 5GHz spectrum analysis, and can't measure 5GHz channel utilization.
All of these features are only available in the most expensive edition, inSSIDer Office + Wi-Spy DBx. These limitations aside, InSSIDer can quickly and accurately measure WiFi signal strength, help you pick the best channel for your home WiFi network, and track the strength of received signals in dBm over time, among other things.
Wifi Analyzer is a Windows 10 app available on Microsoft Store. This simple Windows WiFi analyzer tool is aimed solely at home users, and the basic version is ad-free. The Pro version adds live-tile support, beeper for signal strength, the ability to connect to WiFi networks directly from the app, filters, the ability to disable screen timeout and lock screen rotation, and the option to change signal strength borders.
The good news is that none of these features are essential, so most users can stick with the free version. The one thing WiFi analyzer does great is showing which channels the WiFi networks in your area operate on. If you see that your WiFi network overlaps with several other networks, it’s best to switch to a less busy channel to avoid interference.
Vistumber stands apart from many other WiFi analyzers thanks to its support for GPS and live Google Earth tracking. When Vistumber finds a WiFi network, it plots it on a map, showing its exact location as well as other information, such as encryption, strength, name, and so on.
It’s intended for wardriving, the act of searching for WiFi wireless networks by a person in a moving vehicle, using a laptop or smartphone. Of course, you can also use to identify WiFi network in your home or neighborhood. Unfortunately, the outdated user interface makes the application quite difficult to use.
