Very useful for diagnosing wifi problems

Great app for checking out wifi issues and which channel to set your router to by seeing what your neighbours are using. Also good for working out poor wifi spots in your house by taking the macbook to various rooms in the house. Helped me work out that I improved wifi reception in the bedrooms by moving the router downstairs to an outside wall rather than where it was which was an inside wall near the house centre which was rather counter intuitive as the distance was increased until I worked out it also meant that the line of sight of wifi signal was going through less brick work due to the reduced angle.

Great utility

Want to see why your wifi is slow, conflicting with your neighbours wifi or low signal strength. This is a great utility to see in real time your wifi signal strength, quality, channel usage and determine if your conflicting with other wifi. I have used this app for years and always found it useful to see what is going on and how I can configure or better position my wifi access points for the best coverage.


Great utility for everyone

This works a treat, I use it every time I have a wifi issue at work or home. Whilst I am not a network technical person the app is easy to use and understand. Best use case for me is to identify overlapping wifi signals that may be causing problems, especially when setting up a new network.

This app stays in my kit bag and may only be used once in a while, but it saves me so much time. Well worth it.
