Appreciate the great share. I personally use this myself - however just the app won't be useful if you are attempting a full diagnostic, but it is a good tool.
You're device must have good capabilities. If it is your every day device, your internal antenna degrade over time and readings go off.
Your phone or tablet case will deter the signal as well and give you up to 10 +/- value.
so it is not as useful as a lot of people make it to be.
But I do agree, it potentially is one of the BEST out there for quick check and rough idea on signal strength and degradation and very straight forward and simple.
I personally use it to validate and sort out channel so there is not much noise, but the signal "level" is pointless at times.
How do you use it yourself @jszentir?
(I also know some guys in the tech industry use this exact app as well.)
Once again, Thanks for the share! 😄
Edit: Updated content.
I've seen screen shots of the android app, but I prefer inSSIDer as the graphcal presentation of the networks is very easy most people to understand. This comes in Windows, Mac, and Android versions.
The next version out, which has become a pay version uses the same graphical and text interface but it has been updated to allow the program to display 802.11ac networks and the 802.11ac channel numbers which are different from the N channel numbers. The program can run on a normal a/b/g/n laptop and reads the channel headers to interpret the transmission mode, a/b/g/n/ac and display any and all of those received networks in both graphical and text form. $19.99 US which isn't terribly expensive.
The link that I usually provide here in the forum is for the last freebie version which does not display 802.11ac networks. Either way, android app or inSSIDer, using a application such as those can take the guesswork out of the situation and clarify the problem very quickly. I would encourage anyone with wifi issues to use either one, but my preference is still for inSSIDer.
