Was Broken - now fixed Latest version displays WiFi channels incorrectly in Channel graph mode. For instance device on channel 8 showing as on channel 4. I have read the response from farproc and stand by my comment. Multiple devices running android 6.x exhibit same problem. Will email diagnostic information. App now modified to allow problem feature to be turned off so back to 5 stars!

Works as described, ads problem I like this app for doing trouble calls for cable internet installations. However, I HATE ADS; please ad an ad free version of the app for 99 cents or $1.99. I would be glad to help the development of this app with an add free version. Many utility apps have this option. This is the best wifi diagnostic app out there, I want to support this app.

Beware update This has proven to be extremely valuable app, but latest upgrade shows my personal WiFi on wrong channel. Makes one wonder if it may do the same for other channels. Latest version works fine on Android 4.4.2 phone but not on Android 6.0.1 tablet. ???

Last update Last update has messed up the graph, sadly, as I've relied on it for years. AP List says I'm on channel 6, graph says 10.5 or thereabouts. Channel Rating doesn't seem to work at all.

Channel Rating Issue This must be configured differently from past versions. Now I get no stars on all the channels, and lucky to get 1 star for the best channel. What gives? Reinstalling to prior version.

Works great with some weird results I have always used this tool but lately it is providing annoying results. For instance, looking at channel ratings there is always a better and stronger Channel than the one I am using, but if I change to that channel it looks as if that channel is actually worse than the previous channel. Also, while using a repeater all channels on 2.4ghz have a rating of zero.
