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-AX1800U 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-AX1800U 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.

    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

  • Power Saving

    Better Battery Life for Your Devices

    Target Wake Time (TWT) allows RT-AX1800U 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*.

  • Better Coverage

    WiFi that Goes Farther

    With the latest WiFi 6(802.11ax) standard featuring OFDMA technology, RT-AX1800U 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-AX1800U incorporates ASUS AiProtection, a commercial-grade network security system powered by Trend Micro™ Smart Home Network. With AiProtection, all connected devices are protected, even if they have no antivirus capability of their own — such as IoT devices. AiProtection blocks common internet-based attacks before they reach the network, and if an infected device is detected on the network, AiProtection instantly blocks it to prevent it sending any personal information to malicious servers.
