If anyone tried to find out if strangers would be using your wifi or home broadband without your consent, but your attempts were unsuccessful, there is an application that can help you with your demand. Through Fing network scanner you can detect unwanted “intruders” and even keep them far away.
Once installed, you have automatic access to a list of all devices connected to your router, even allowing you to enable alerts when new devices access the network. By clicking on one of the devices recognized by the application, it is possible to know details such as IP, MAC address and even its make and model.
Fing also allows you to check your network connection speed through its "Speed Test" functionality. In addition, the app even features a function dedicated to parents who want to help their children spend less time in front of their computer or smartphone screens.
