Keep Strangers Off Wi-Fi

To prevent strangers from using your Wi-Fi network, change the password to a long, unique one, enable WPA3 or WPA2-AES encryption, disable WPS and unnecessary features, and update your router’s firmware regularly. Check the list of connected devices and create a separate guest network. If you spot an unfamiliar device, change both the Wi-Fi password and the router’s administrator password, then reconnect only trusted devices. Hiding the network name alone doesn’t provide real protection. Slow internet or unusually high data usage can also have other causes, so check the device list before drawing conclusions.
