The Ultimate Wireless-N Router for Gaming and Multitasking
RT-N18U features top-of-the-line hardware specifications. An 800MHz processor with high clock speed delivers fast and responsive USB and WAN to LAN performance; while TurboQAM™ technology raises the 2.4 GHz band speed from 450 Mbps to 600 Mbps for a 33% boost. 128MB flash and 256MB RAM ensure a massive data pipeline of up to 300,000 data sessions and multitasking capability, making it perfect for gaming or high-load network environments. The energy-efficient ARM-based CPU reduces power consumption to even help you save on the bills. In addition, ASUS AiRadar intelligently strengthens wireless connectivity using universal beamforming, high power amplification and exclusive ASUS RF fine-tuning for a 150% increase in coverage1 , so even legacy 802.11b/g/n clients can benefit from this technology.
RT-N18U also incorporates more user-friendly and intuitive software. With the ASUSWRT interface, you can easily set up the router within 30 seconds2, or switch RT-N18U between its various modes. You can optimize speed with the built-in Smart QoS function, or turn the USB storage attached to the router into a personal cloud with ASUS AiCloud.

Boost your Wi-Fi performance
RT-N18U features TurboQAM™ technology that boosts 2.4 GHz wireless speeds from 450 Mbps to up to 600 Mbps for 33% faster Wi-Fi performance. Now everything you do online is done faster.

Gigabit Internet surfing with Turbo NAT
Equipped with Turbo NAT and built-in Gigabit Ethernet, RT-N18U gives you full Gigabit internet performance, making its WAN to LAN throughput up to 2-5 times that of traditional software-based NAT Gigabit routers. Turbo NAT handles simultaneous wired connections, achieving maximized total concurrent speeds. So go ahead: game, stream and download from desktops, notebooks, tablets, smartphones and game consoles at once minus the performance loss.

Extend and strengthen your wireless connection
ASUS AiRadar intelligently strengthens wireless connectivity using universal beamforming technology, high power amplification, and exclusive ASUS RF fine-tuning. This ensures extended coverage, dynamic data speed increases, and enhanced stability and is backward compatible with 802.11b/g/n clients. Because connection strength varies based on your environment, RT-N18U uses three external antenna to detect wireless device locations and shape transmissions so they’re optimized for the fastest, most stable connection strength.
