Know if your neighbors are stealing your WiFi connection .

Command Prompt can let you know if someone is connected to your Local Area Connection and using it.

Just follow the steps:-

1- Open your browser and visit http://192.168.1.1 or http://192.168.0.1 depending on your router.

2- Find the tab that mentions “Attached Devices” or something similar.

3- Find the computer name, IP address and MAC Address (sometimes called Physical Address or Hardware Address) of your computer [you can know your IP address, DNS Server's address and a lot more about your Internet Connection by typing "ipconfig/ all" without quotation in the command prompt and press Enter.]

If you notice some strange devices, then your neighbour has been sneaking in on your internet connection and it is best to set a password.
