Keeping your wireless network secure protects your personal information and keeps outsiders from using your network without permission. If you’re worried about people using your Wi-Fi network without your permission, you can log in to your router’s settings menu and see a list of all devices that are currently connected, allowing you to see what -- and who -- is on your network.
