ASUS RT-AX53U AX1800 Dual Band WiFi 6 Router (802.11ax)
The ASUS RT-AX53U is an AX1800 dual-band WiFi 6 router built for homes that need reliable coverage and multi-device efficiency. It combines WiFi 6 (802.11ax) with MU-MIMO and OFDMA technology to let multiple devices communicate simultaneously without congestion, and runs AiProtection Classic security powered by Trend Micro to block malicious sites and infected devices.
Why this product
WiFi 6 with dual-band speed
1201 Mbps on 5GHz and 574 Mbps on 2.4GHz adds up to 1800 Mbps total. OFDMA divides channels into sub-channels that travel up to 80% farther, giving better coverage throughout your home.
Four Gigabit ports for your devices
One WAN and three LAN ports let you connect a smart TV, game console, NAS, or backup internet—each with its own 10× faster Gigabit connection instead of shared bandwidth.
Simultaneous multi-device support
MU-MIMO and OFDMA efficiency let your phone, laptop, and IoT devices talk to the router at the same time without waiting for each other. Reduces latency for smoother performance.
Built-in security and parental controls
AiProtection blocks malicious sites and infected devices. Guest network isolates visitors from your local files. Traffic monitoring and bandwidth limiter let you manage usage.
Expandable with AiMesh
Works as a primary router or node in an ASUS AiMesh system, letting you add coverage without replacing your existing setup.

RT-AX53U is a 2x2 dual-band WiFi router that provides 80MHz bandwidth and 1024-QAM for dramatically faster wireless connections. With a total networking speed of about 1800Mbps — 574Mbps on the 2.4GHz band and 1201Mbps on the 5GHz band — RT-AX53U is 1.5X faster than 802.11ac 2x2 dual-band routers.
OFDMA support in the WiFi 6(802.11ax) standard divides each channel into small sub-channels, allowing signals from multiple devices to be bundled together and transmitted simultaneously, reducing latency for a smoother, more responsive WiFi experience.
These sub-channels have a smaller bandwidth that enables them to travel up to 80% farther, resulting in a better WiFi connection throughout your home.
RT-AX53U has one Gigabit WAN port, three Gigabit LAN ports, and USB 2.0 port. Smart TV, game consoles, NAS storage devices, backup internet and more can now have their own dedicated ports, making RT-AX53U your solid digital home hub.
