Why move to 802.11ax Wi-Fi?

Network security for peace of mind
Powerful Whole-home Wi-Fi System
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 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 802.11ax WiFi standard.

Next-Gen WiFi Speed
RT-AX55 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-AX55 is 1.5X faster than 802.11ac 2x2 dual-band routers.

Power Saving
Better Coverage
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 802.11ax WiFi 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.

In the past: 1 device processed at a time
802.11ac OFDM
Bandwidth wasted - Higher latency

Now: Multi-devices processed simultaneously
802.11ax OFDMA
Bandwidth fully utilized - Lower latency

Protection for your Home Network
RT-AX55 has lifetime free AiProtection Classic, powered by Trend Micro™ with automatic, regularly updated security signatures to protect your devices and personal data from internet threats. This strong security offers parental controls, including the ability to block specific websites and mobile app types.

AiMeshPowerful Whole-home WiFi System.
The Way You Want.
In most cases, your RT-AX55 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!

* To benefit from 802.11ax features, the WiFi client needs to be 802.11ax capable.
** Actual 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.
*** Quoted network speeds and bandwidth based on current IEEE 802.11ax specifications. Actual performance may be affected by network and service provider factors, interface type, and other conditions. Connected devices must be 802.11ax-compatible for best results.
