Get Your Home Ready for WIFI 6 (802.11ax)
The growing number of connected personal and IoT devices has led to an overall increase in network density that is pushing the limits of the current WIFI standard. The latest WIFI 6(802.11ax) standard provides future-proof technologies, higher network efficiency, faster WIFI speeds, greater coverage and improved battery life for connected devices, providing a significantly better networking experience for users.
*It requires 802.11ax-compatible devices to enjoy the benefits brought by WIFI 6(802.11ax) standard.
Next-Gen WIFI Speed
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.
Network Efficiency

Built for Multi-Device Households
With a revolutionary combination of OFDMA and MU-MIMO technology, 802.11ax technology provides up to 4X greater network capacity and efficiency in traffic-dense environments. Previous-generation 802.11ac WIFI can only handle one device at a time on each network channel, which is an inefficient use of available bandwidth. 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.
- 802.11ac OFDM: Bandwidth wasted - Higher latency
- 802.11ax OFDMA: Bandwidth fully utilized - Lower latency
Power Saving
Better Battery Life for Your Devices
Target Wake Time (TWT) allows RT-AX53U to schedule designated intervals for devices to transmit data. This allows them to sleep when there is no need to wait for a router signal, reducing power consumption by up to 7X for significantly improved battery life*.
- Without Target Wake Time 802.11ac - Higher Device Power Consumption
- With Target Wake Time 802.11ax - 7X better battery life for client devices
Better Coverage

WIFI that Goes Farther
With the latest WIFI 6(802.11ax) standard featuring OFDMA technology, RT-AX53U provides increased WIFI signal range and better coverage by dividing each channel into smaller sub-channels. These sub-channels have a smaller bandwidth that enables them to travel up to 80% farther1, resulting in a better WIFI connection throughout your home*.

Protection for Your Home Network
RT-AX53U incorporates ASUS Ai Protection, a commercial-grade network security system powered by Trend Micro™ Smart Home Network. With Ai Protection, all connected devices are protected, even if they have no antivirus capability of their own — such as IoT devices. Ai Protection blocks common internet-based attacks before they reach the network, and if an infected device is detected on the network, Ai Protection instantly blocks it to prevent it sending any personal information to malicious servers.
Powerful Whole-Home WIFI System. The Way You Want.
In most cases, your RT-AX53U can deliver smooth, reliable WIFI to every part of your home. But WIFI coverage can be affected by many factors — room layout, construction materials, and even furnishings. ASUS AiMesh is an innovative new router feature that fixes these problems: it creates a whole-home WIFI network using multiple ASUS routers. AiMesh is powerful, flexible and you can use a mix of ASUS router models — protecting your investment! AiMesh gives you time-saving central control, and seamless roaming capability. AiMesh is WIFI you can rely on — for all your devices, all the time!
- Turn your ASUS routers into whole-home WIFI system with a simple firmware update
- Mix and match preferred models from selected ASUS routers
- Create a WIFI network with either a single SSID or multiple SSIDs
- All router features works across the entire WIFI system

Connectivity Options
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.
Robust Control and Optimization with ASUSWRT
With the ASUSWRT dashboard UI, setup, monitor, and control network applications all in one intuitive area. With fast setup, multi-device detection, and flexible settings, ASUSWRT makes the most of your network performance.
*xActual data throughput and WIFI coverage will vary from network conditions and environmental factors, including the volume of network traffic, building material and construction, and network overhead, result in lower actual data throughput and wireless coverage.
Disclaimer
*The external hard drive may need an external power to work with USB application.
