Best One Ever Used

NetSpot is an excellent tool for troubleshooting and managing Wi-Fi. It displays a large amount of data in a format with color-coding that is easy to understand.

Easily identify busy and noisy channels to be avoided by sorting columns by SSID, Channel, SNR Level, Signal, Noise and many more. In my environment, channels 6, 11, 1 and 9 were problematic. Channel 3 is providing a strong and stable signal.

Even without mapping, this is the best of the many Wi-Fi apps I have used.

Highly recommend!
