ASUS Zen WiFi ET9 3PK offers flexible backhaul options: allowing you to choose between wireless or wired Ethernet speeds. You can manually select the type of backhaul connection, or you can let the router intelligently choose the most reliable method based on connection quality. Home network security is more important than ever, as many households now have multiple connected devices while lacking appropriate security measures to protect them and their users. The ASUS Zen WiFi helps you stay safe online with our Ai Protection Pro network security and Instant Guard secured VPN features.
