The New Era of Home WiFi

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) provides future-proof technologies, higher network efficiency, faster Wi-Fi speeds, greater coverage and improved battery life for connected devices, providing a significantly better networking experience for users.

Warp-speed WiFi

RT-AX88U is a 4x4 dual-band WiFi router that provides 160MHz bandwidth and 1024-QAM for dramatically faster wireless connections. With a total networking speed of about 6000Mbps — 1148Mbps on the 2.4GHz band and 4804Mbps on the 5GHz band — RT-AX88U is 2.3X faster than 802.11ac 4x4 dual-band routers.

Built for Multi-device Households

With a revolutionary combination of OFDMA and MU-MIMO technology, WiFi 6 (802.11ax) provides up to 4X greater network capacity and efficiency in traffic-dense environments. Previous-generation WiFi 5 (802.11ac) 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 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.

Better Battery Life for Your Devices

Target Wake Time (TWT) allows RT-AX88U 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.

WiFi that Goes Farther

With the latest WiFi 6 (802.11ax) featuring OFDMA technology, RT-AX88U 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.

Give your Online Gaming a Double Boost

RT-AX88U's Adaptive QoS prioritizes game packets for smoother online play. It also has built-in wtfast® to seek out and secure the shortest possible path between your gaming device and the game server, minimizing game ping and lag.

Commercial-grade Security for your Home Network

RT-AX88U has lifetime free AiProtection Pro, powered by Trend Micro™ with automatic, regularly updated security signatures to protect your devices and personal data from internet threats. This strong security offers advanced parental controls, including the ability to block specific websites and mobile app types.

More LAN Ports for
More Convenience

Eight Gigabit LAN ports make RT-AX88U the ideal solution if you have multiple wired devices, such as NAS systems, PCs and switches. And, if you ever want to host a LAN party at home, RT-AX88U makes it possible.

Wireless that's as Stable as Wired Ethernet

When you are far away from your router, enjoying the stability of a wired network connection is usually impractical or impossible. With special designed antennas, AiRadar beamforming and RangeBoost technology, RT-AX88U provides wide coverage and a stable signal, letting you enjoy a reliable and smooth connection for gaming or work anywhere in your home.

Powerful Whole-home Wi-Fi System.
The Way You Want.

In most cases, your RT-AX88U can deliver smooth, reliable Wi-Fi to every part of your home. But Wi-Fi 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 Wi-Fi 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 Wi-Fi you can rely on — for all your devices, all the time!

- Turn your ASUS routers into whole-home Wi-Fi system with a simple firmware update
- Mix and match preferred models from selected ASUS routers
- Create a Wi-Fi network with either a single SSID or multiple SSIDs
- All router features works across the entire Wi-Fi system

Extreme Power with 1.8GHz Quad-core CPU

RT-AX88U features a top-of-the-line 1.8GHz 64-bit quad-core CPU that is more powerful than many desktop processors. With its incredible performance, RT-AX88U maximizes throughput for the best networking performance, accelerates USB data transfers and more.

In addition to LAN port aggregation, RT-AX88U supports WAN port aggregation, which combines gigabit WAN and LAN ports to deliver internet speeds of over 1Gbps*. This eliminates the 1G bottleneck from WAN port, a great choice if you have over 1Gbps internet from the internet service provider.
*To access WAN port aggregation, cable modem, router, or switch needs to support 802.3ad standard. To achieve the best performance for a cable modem, DOCSIS 3.1 standard is required.
