You can use your router’s guest network to provide your guests with access to the Internet while restricting their access to other resources on your local network. To prevent unauthorized users from accessing the Internet, your guest network requires a password that will keep the unwanted user away. The guest network is enabled by default. Your wireless network SSID name and password were set when you ran the router’s setup software, but you can change them at any time using the linksyssmartwifi.com interface.
