NetSpot is arguably the best WiFi tester app ever created, and it’s certainly the favorite WiFi tester app of hundreds of thousands of professional and home users alike, who all appreciate its modern user interface, complex features, great customer support, and attractive price. NetSpot has two distinct modes of operation: Discover and Survey. The Discover mode creates an instant snapshot of nearby wireless networks and gathers all available information about them. The Survey mode, on the other hand, allows for the creation of in-depth wireless site surveys to visualize where exactly is the signal strongest and where it is the weakest. With NetSpot, you don’t need to be an expert to gain enough insight into the state of your wireless network to see where the problem is and understand how you can solve it.
Acrylic WiFi is another popular WiFi tester app capable of analyzing 802.11/a/b/g/n/ac wireless networks. Compared to NetSpot, Acrylic WiFi has a lot less user-friendly interface, which may put off less experienced users. That said, the company behind Acrylic WiFi offers comprehensive WiFi testing training courses intended to turn beginners into pros. If you’re willing to invest some time into learning how to use this free WiFi tester app, you may even consider eventually upgrading to the Pro version or purchase the Heatmaps add-on to gain an even deeper understanding of wireless networks around you.
WiFi Analyzer is the simplest WiFi tester app on this list, and it’s also the easiest to install because you can download it straight from the Windows Store. The app can gather basic information about nearby wireless networks and help you find the best channel to broadcast on, but that’s where its capabilities end. Because WiFi Analyzer is a modern Windows app, you can also run it on mobile devices with the Windows Mobile operating system, which is far more convenient than always carrying a heavy laptop around.
