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.

Better Battery Life for Your Devices

Target Wake Time (TWT) allows RT-AX1800S 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) standard featuring OFDMA technology, RT-AX1800S 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-AX1800S 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.
