A (s)imple, (l)ight(w)eight, wlan / wifi scanner widget. It displays the wlan / wifi networks in your neighborhood. This will help you to find a free channel and configure your own wlan network on a channel which is not allready occupied. No ads. 100% fat free. Only 22 Kb small so it won't eat up your device storage space. It starts to scan once you push the "scan" button. Push the "stop" button to ...guess what... stop scanning!
First Number is Channel Number, second is signal level, the last column is the network name.
It needs 3x2 cells on the home screen.
This is a widget so you need to drop it on your homescreen it is not an app.
If you like more of those simple, lightweight widgets which only ask you for the permissions they realy need and don't fill up you phone with Megabytes of data even if they need to do only a small job then check the other SLW widgets.
