If the wireless network is not secured, anyone with a wireless client can connect to your network, use your Internet connection, and access your computers.
With minimal effort, you can secure your router to prevent unauthorized wireless devices from connecting to your network, using your Internet connection, or modifying your router’s configuration.
SecureEasySetup configures your wireless security method to WPA2 and WPA (PSK) with TKIP and AES encryption.
For additional security, you can allow only specific devices to connect to the router (MAC filtering). If you won’t have any wireless devices connecting to this router, you can disable the wireless features of the router. This will prevent any wireless devices from connecting to your router. These features and more (such as 802.1x) can be accessed on the router’s Security page after the setup is complete.
