The Wi-Fi Awards Product of the Year

This is my go-to tool for doing quick sanity checks and making sure radio settings are correct.

Robert K., Wireless Engineer

I recommend it as the very first purchase for my Wi-Fi customers who need to understand how to verify their installation and improve its performance.

Joshua W., Mobility Architect

This provides a lot of features you need for troubleshooting issues, and makes it easy for even non-WiFi experts to understand.

Jonathan D., Wireless Engineer

This takes much of the mystery out of the inherently mysterious realm of Wi-Fi networking.

This is absolutely the best WiFi scanning / troubleshooting tool I have used. It is reliable, stable, and has just the right mix of features. I would highly recommend this to anyone looking to troubleshoot / design / optimize their WiFi.

benjsnyder, Mac App Store

I’m not a network admin, but I’m fairly familiar with wireless networking and find that this tool is good visualizing what’s happening with the wireless channels around me. The UI is nicely laid out, the app works well.

SocialGamer11, Mac App Store

This is by far one of the most useful tools I have used and one of the reasons I even stick with Macs instead of going to Windows.
