Furthermore, the RT-BE58U is AiMesh compatible. This means it can be paired with other supported ASUS routers to create a whole-home mesh network, extending coverage under a single network name (SSID). The WiFi 7 MLO technology is integrated into this AiMesh system for potentially more stable backhaul connections.
Security and Smart Home Management
Security is a major selling point. The router includes AiProtection Pro, a commercial-grade network security suite powered by Trend Micro. This provides 24/7 protection with features like a one-tap security scan, safe browsing, and protection against inbound and outbound threats without a subscription fee. The “Smart Home Master” feature simplifies network segmentation by allowing users to easily create up to three dedicated SSIDs: an IoT Network for smart devices, a Kid’s Network for parental controls, and a VPN Network for instant VPN connections. The parental controls are built-in and do not require a monthly subscription, offering tools to manage screen time and filter content, though user experiences with filtering precision vary.
Setup, Support and Ownership
