How do I set up a guest WiFi network on the CAX80?

Log in to the router at routerlogin.net, then select Guest Network from the menu. Enable the guest WiFi network for the 2.4 GHz or 5 GHz band by selecting the Enable Guest Network check box, and configure the SSID and security settings as needed. By default, guest network clients cannot access devices on your main network, but you can allow this by selecting 'Allow guests to see each other and access my local network.' (Pages 52-54)
