Fast Speed. Wide Coverage. Easy Setup.

Enter a new era of wireless performance with faster-than-incredible speeds, the widest-ever coverage and more control and security than you ever thought possible. RT-AC87U delivers the world's fastest speeds of up to 1734Mbit/s at 5GHz — even faster than tri-band 3x3 routers — plus class-leading concurrent 600Mbit/s speeds at 2.4GHz for an amazing total bandwidth of 2334Mbit/s! This means RT-AC87U gives you lag-free online gaming, silky-smooth 4K/UHD video streaming, and effortlessly copes with even the most bandwidth-demanding tasks. 

With a separate high-gain antenna for each of the four spatial data streams, this power-packed router gives you true 4x4 multi-user MIMO (MU-MIMO) wireless performance that smokes the competition — and it delivers top performance for all your wireless devices, even those using older Wi-Fi standards. As with all ASUS networking products, you get the very best support with the widest range of device compatibility, plus free firmware updates for years to come — so your RT-AC87U will always be at the forefront.



RT-AC87U is designed for pure performance — as well as its main 1GHz dual-core processor, RT-AC87U also has a separate dual-core processor that's dedicated solely to 5GHz 4x4 Wi-Fi related tasks. This means that compared to routers with a single 1.2GHz dual-core processor, RT-AC87U has Wi-Fi-to-USB transfer speeds that are up to twice as fast3, and can show up to a 50% improvement in total throughput on a heavily-loaded network with multiple clients!4

RT-AC87U is not only fast, but looks stunning too. Inspired by the gamer-centric ASUS Republic of Gamers G Series notebooks, RT-AC87U is designed with Stealth Fighter-like curves that exude power and sophistication. It's VESA-mount-compatible too, so you can literally take RT-AC87U to new heights on your wall!



Enjoy a new level of wireless performance, with 2334Mbit/s of combined 802.11ac and 802.11n bandwidth. With class-leading speeds of up to 600Mbit/s on the 2.4GHz band — thanks to Broadcom® TurboQAM™ technology — and up to 1734Mbit/s concurrently on the 5GHz band, which is even faster than the latest tri-band 3x3 routers, RT-AC87U leaves the competition standing.

At the forefront of technology

RT-AC87U doesn't lead others, it dominates, offering the best current-generation performance for all your notebooks, smartphones and other wireless devices.


Boasting a true four-stream, four-antenna (4x4) design, RT-AC87U gives you up to 465m2 (around 5,000ft2) of wireless coverage1. That's 33% more than the latest generation tri-band routers5, making it the ideal choice for large homes and multi-floor buildings. Thanks to AiRadar beamforming and unique multi user-MIMO (MU-MIMO) technology, the more devices you use the more the throughput increases6.



For the fastest wired networking performance, RT-AC87Ucomes with a dedicated Gigabit WAN port, five 1000Mbit/s Gigabit Ethernet LAN ports (one of which can be used as a second WAN port), and hardware-accelerated NAT. Unlike the traditional software-based NAT used in most other routers, RT-AC87U's hardware NAT removes the bottleneck between the wired LAN and the internet, allowing you to get the most out of modern super-fast broadband connections.



RT-AC87U, like all ASUS networking products, is subjected to exhaustive compatibility testing during its development. RT-AC87U works flawlessly with a vast range of adapters, media players and other wireless devices to ensure the best performance — it even supports the latest-generation Xbox® One and PlayStation® 4 game consoles.

Powerful online multitasking

With its massive data pipeline of up to 300,000 data sessions, RT-AC87U has around 20 times the networking capacity of conventional routers for exceptionally smooth performance.

Time Machine® support

Supports Time Machine® backups with Apple devices.
