Incredible performance with incredible control!

ASUS RT-AC1900U dual-band wireless-AC1900 gigabit router delivers incredible performance and coverage range. With new ASUSWRT UI, quickly setup your network, customize user access, and monitor signal strength. The RT-AC1900U concurrent both 5 GHz and 2.4 GHz transmission up to 1900 Mbps that makes it ideal for bandwidth demanding tasks such as 3D HD video streaming, multiplayer gaming, USB hard drive file sharing, and USB connected printer sharing. Built-in Wi-Fi amplifiers make the RT-AC1900U the perfect wireless router for larger, multi-level homes and buildings with signal range that reaches virtually any area.

World's fastest AC Wi-Fi with TurboQAM™ Wi-Fi

Powered by 5th generation Wi-Fi (5G Wi-Fi), the new 802.11ac chipset gives the RT-AC1900U superfast Gigabit wireless speeds. What's more, RT-AC1900U uses TurboQAM ™ technology to upgrade 2.4G Wi-Fi even further to give you unprecedented speeds. At 2.4GHz, it's 33% faster than generic wireless-N900 routers, reaching 600 Mbps, while on the 5GHz band it blazes to 1300Mbps – or triple 802.11n rates. That's 1900 Mbps of concurrent wireless power!

Do more at once with dual-core processors inside

The ASUS RT-AC1900U features a dual-core processor that eliminates the performance drops that plague other routers. So even on the busiest home networks, HD video streaming is smooth, the latency low for online gaming and VoIP calls, and file downloads are uninterrupted.

Unbeatable Wi-Fi coverage

With the powerful antenna design, both Wi-Fi range and signal stability improve dramatically. AiRadar beamforming further focuses Wi-Fi signal on your devices, making your Wi-Fi faster, clearer and stronger.

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

In most cases, your RT-AC1900U 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

Ultimate USB speed and versatility

USB 3.0 features data transfers up ten times faster than USB 2.0. Two USB ports make the RT-AC1900U perfect for file, multimedia, and 3G/4G sharing, while ASUS AiDisk offers remote access and quick content streaming. Where other routers have their USB ports sandwiched next to one another, both RT-AC1900U USB ports are evenly spaced for easy access to either at all times.

ASUS Router APP Control Your Network Anywhere

In your increasingly mobile-enabled life, having control over your network via an app is more important than ever. The new ASUS Router App is built from the ground-up to be both intuitive and robust, allowing you to setup your router, manage network traffic, diagnose connection issues and even update firmware, all without needing to boot up a PC.
