Graphs no longer work

Currently the app is at 50% funcionality. Looks like it has not been updated in a while.

Try enabling location services. Enable location services https://support.accessagility.com/hc/i-updated-to-macos-mojave-why-am-i-only-seeing-one-result-in-scans

Stopped working, But there is a FIX!

I guess it stopped working when i upgraded to High Sierra or catalina not sure when.. But bascially i was only able to see 1 wifi network in the scan which was odd. This app always worked beautifully before. Turns out, all you had to do was enable Location Services, unders system preferences > security > Privacy..

back to 5 stars

Extremely useful for diagnosing Wifi issues

This app does a great job of showing all the APs near you, along with a great deal of information about each one. It graphs out signals on both 2.4 GHz and 5 GHz bands.

The interface can start off pretty cluttered with tons of SSIDs, but a little tweaking will eliminate the clutter and help you see exactly what is on each channel.

A great inSSIDer alternative.
