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 backwards compatible with 802.11b/g/n clients. Because connection strength varies based on your environment, RT-N18U uses three external antennae to detect wireless device locations and shape transmissions so they’re optimized for the fastest, most stable connection strength.
