Quick video guide for setting up a guest network on an ASUS router. In this tutorial I'm using an ASUS RT-AX88U, but the proces is the same for most ASUS routers.
When you have set up your ASUS wireless router and connected to the Internet, and want to share the wireless (Wi-Fi) with your family and friends, you can create an independent wireless network environment through the guest network feature. For example: provide guests with a different Wi-Fi name and password from your original Wi-Fi, to prevent guests from browsing data shared on your network and increase the security of your network connection.
