ASUS RT-AX58U (RT-AX3000) Wi-Fi 6 Dual-Band Router

The ASUS RT-AX58U, also marketed as the RT-AX3000, is a dual-band Wi-Fi 6 (802.11ax) router built for homes that need reliable, high-speed wireless coverage without the cost of a premium mesh system. With combined theoretical speeds of up to 3000 Mbps (574 Mbps on 2.4 GHz and 2402 Mbps on 5 GHz), it delivers strong performance for streaming, gaming, and multi-device households.

Under the hood, the RT-AX58U is powered by a 1.5 GHz tri-core Broadcom processor paired with 512 MB of RAM and 256 MB of flash storage. It supports 160 MHz channel bandwidth and 1024-QAM modulation, both of which contribute to faster real-world throughput compared to older Wi-Fi 5 routers. OFDMA and MU-MIMO technology allow the router to communicate with multiple devices simultaneously, reducing latency and improving efficiency in busy network environments.

Security is handled by AiProtection Pro, powered by Trend Micro, which is included free for the lifetime of the router. This provides automatic malware blocking, intrusion prevention, and advanced parental controls that let you filter content and set usage schedules per device. WPA3 encryption is also supported for stronger wireless authentication.

On the hardware side, the RT-AX58U features one Gigabit WAN port, four Gigabit LAN ports, and a single USB 3.2 Gen 1 port for connecting external storage or a 3G/4G LTE dongle. Four external antennas with beamforming help direct signal toward connected devices for better range and stability.

ASUS AiMesh compatibility means you can pair the RT-AX58U with other AiMesh-capable ASUS routers to create a whole-home mesh network without replacing your existing hardware. Setup and management are straightforward through the ASUS Router app for iOS and Android, or through the web-based interface at router.asus.com. The router also supports Amazon Alexa and IFTTT integration for voice commands and automation.
