Ever wondered why your WiFi setup at home suddenly stopped working as good as before? Check this..
Every WiFi / access point will provide its signal with one of 14 or 16 (depending on brand) frequencies called channels. If you are on the same channel your neighbor is on, chances are there is signal interference/distortion. You have to log in your device settings and change the channel.
Here is the problem though..how are you going to know the channels the other WiFis are connected to? WiFi Analyzer app is the solution through which thou will be able to scan surrounding devices. It will provide you with the necessary info.
As you can see on the screenshot these WiFis are connected on the same channels but their owners are probably not aware of it. One day when the interference becomes so strong they will have to change the channels or experience problems in connectivity.
