- Dual-band (2.4 + 5 GHz) AC2900 wireless router with the latest 802.11ac MU-MIMO technology for data transfer speeds up to 2900 Mbps
- 1.8GHz 64bit Dual-Core processor optimizes network traffic and connectivity speeds from the USB 3.1 Gen1 and 4x Gigabit LAN ports
- Designed for lag-free online gaming and flawless 4K UHD streaming with WTFast® Game Accelerator and Adaptive QoS
- AiProtection Powered by Trend Micro™ provides built-in 24/7 protection from external attacks and threats, neutralizing them before they reach your network or connected devices
- Manage your network with the ASUS Router app - setup your network, manage usage and parental controls, even get instant notifications about important network-based events

Furiously Fast. Powerfully Equipped.

ASUS RT-AC86U is the ultimate choice for gaming, with blistering 2917Mbps Wi-Fi speeds, MU-MIMO technology and powerful game-boosting features including the WTFast® game accelerator and Adaptive QoS.

Ultrafast Wi-Fi with NitroQAM™ Technology

Whether you're gaming online in a heated competition or streaming a live event in 4K UHD, lag and buffering are simply not an option. NitroQAM™ (1024-QAM) technology on the RT-AC86U delivers a combined 2917 Mbps Wi-Fi speed, ensuring everyone on your network can enjoy smooth streaming and low-latency online gaming.

Double Gaming Boost

Enjoy low-latency online gaming with boosted internet and home network performance!

Free Game Accelerator Inside

Ping time and variance are critical technical parameters that affect responsiveness in online gaming, and their values depend heavily on the route game packets take to and from their destination. The Gamers Private Network® (GPN®) from WTFast® automatically performs route optimization, choosing the most efficient route for game packets, resulting in consistently-lower ping time and minimal packet loss. With RT-AC86U this optimization is free for accelerating one selectable device at a time, so you can enjoy the results on supported competitive multi-player online games.

Adaptive QoS - Prioritize Your Game

Boost your gaming bandwidth with Adaptive QoS (Quality of Service), which allows you to easily prioritize gaming packets and activities. You can even assign full dedicated bandwidth while gaming under gamer solo mode, making RT-AC86U the perfect ally for low latency gaming anywhere in your home. It supports major consoles including PlayStation®3, PlayStation®4, PS4™ Pro, PlayStation®Vita, Wii U, 3DS and Xbox One.

Multiple Capacity Wi-Fi with Revolutionary MU-MIMO Technology

MU-MIMO gives every compatible device3 its own dedicated full-speed Wi-Fi connection, so that multiple devices can connect at the same time without slowing down the network.
In fact, RT-AC86U is able to connect to multiple MU-MIMO-compatible clients at each device's maximum speed simultaneously, unlike standard single-user MIMO where individual devices have to wait for sequential transmissions.

Unbeatable Coverage

With ASUS innovative antenna design and the new Range Boost technology, both Wi-Fi range and signal stability improve dramatically. AiRadar further focuses Wi-Fi signal on your devices, making your Wi-Fi faster, clearer and stronger.

Powerful Processor, Faster Transfers

RT-AC86U's top-of-the-line 1.8 GHz dual-core processor brings its computational capability to the next level. USB data transfers enjoy up to over 110 MB/s speed and the router download/upload speed (WAN-LAN throughput) up to 1600 Mbps.

AiProtection - Your Digital Playground is Protected

RT-AC86U 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.

Fortified Frontline Network Security

Networking is only half the equation when it comes to game performance. As AiProtection is integrated in RT-AC86U and powered by the router, even if a device's security software isn't turned on - to get around blocked games, for example - AiProtection still protects the network from attacks and intrusions, for added peace of mind.

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, all without needing to boot up a PC.
One-click Game Boost Easy Router Setup Real-time Traffic Monitering
Clever Network Diagnosis Effortless Guest Wi-Fi Sharing Handy Firmware Update

ASUSWRT - Easily Control Your Network

RT-AC86U features the enhanced, intuitive ASUSWRT user interface, which gives you easy access to both the 3-step web-based installation process and a wealth of robust advanced options.

Connectivity Options

RT-AC86U has four Gigabit LAN ports, USB 2.0 port and USB 3.1 Gen 1 port. Smart TV, game consoles, NAS storage devices and more can now have their own dedicated ports, making RT-AC86U your digital home hub.

Your Sharing Center

With built-in USB 3.1 Gen 1 and USB 2.0 ports, you can connect USB-enabled devices, such as external storage drives, printers, or a 3G/4G dongle to your ASUS router and share them conveniently with other users via Wi-Fi. And with USB 3.1 Gen 1, you can enjoy up to 10X faster data transfer speeds.

4 X the speed of my ISP's

This router has completely changed my internet experience. My household had many devices connected to my ISP's Spark Huawei HG630b router which was crippling the connectivity and speed. The Huawei was never good to start with. The WIFI signal on the ASUS 86U covers my 5 bedroom house with 100 strength. Even the LAN connection is faster than the Huawei LAN.

To get this particular model working with Spark fill out the normal WAN settings that are shown on PB Tech with the 68U but you have to go to another menu to get it working with this model.

Excellent replacement for

Purchased to replace the router provided by Vodafone for a fibre connection

-Much better Wifi coverage
-Noticeably better throughput on wired and wireless connections
-Management interface provides much more functionality and control

-Setting up the required VLAN for Vodafone fibre was non intuitive, setting is hidden in the LAN - IPTV settings and is labelled Internet VID, luckily PBTech have good guides available here

To replace ISP router

Brought this to replace Vodafone HG659 router. Was forever having issues with WIFI signal dropping. Since buying this have had no loss of WIFI signal, may not have picked up better speeds (haven't noticed), but definitely more stable and covers more area. Didn't take into consideration that i could no longer use my landline with Vodafone if replacing their router, as they do not give out the information to put on a 3rd party router, so had to cancel my phone line with them, but intend on going with another provider and buying an ATA for VOIP. Highly recommended product.

Great router, good WiFi p

I purchased this router to solve 2 main issues of my ISP provided fibre router. Firstly WiFi coverage and secondarily inconsistent gateway performance.

To set it up as a fibre router the VLAN settings are only set by adding a manual LAN config for "IPTV". The PB Tech setup instructions work exactly as provided, but from a router setup point of view it's not intuitive that you're setting egress traffic to be tagged. That aside, once set it works very well.

WiFi performance was poor due to having a larger two-story house with a number of walls for the poor signal to have to travel through. I didn't expect performance to be amazing still b...view more

I did a lot of homework prior to purchasing this product suspecting it wasn't going to do what I wanted - high-speed wireless coverage throughout a two level house.

I persevered with my ISP's adequate (802.11n) router with two access points and was never satisfied. The Asus RT-AC86U is fabulous! I get a solid 45-50dBm coverage throughout our 220 sqm house with just the Asus router and near cabled speed - 97-98 Mb down and 48-49 upload in most places. As a Mac user, I love the built-in Time Machine function and the iPhone app is really convenient.

Security - great. Ease of install - couldn't be easier. Future proof - yep. Downside - pe...view more

Don't buy if you have a smart home

The Good:
All lan internet is fast
Good range with 5Ghz and 2Ghz

The Bad:
The 2.4ghz drops out, a lot. I've sent mine back because smart home tech requires a good 2.4ghz connection. Read the reviews on amazon, many people having the same issue. Thankfully PB have come to the party with a credit.

Good - when it works.

In general this is a good router: speeds are fast, and most of the time it works well. However, the router is far from perfect. Every two weeks or so, the router either disconnects from the internet, or it refuses to connect to any device on the network. This is fixed by a restart, but it should not be happening in the first place. Time Machine backup makes the problem much worse and causes multiple disconnections throughout the day (this "feature" is too much hassle to bother with due to the problems it creates). For people who want a RELIABLE router, I recommend looking elsewhere. Sadly, like many tech products these days, these...view more

Awesome Router

Technical difficulties at Slingshot's end made setup a bit lengthy but once connected it has been awesome. The strength and coverage of the WiFi signal is second to none, speed has been improved too consistently achieving 500mbps. Delivered overnight. Thanks for the great recommendation PB Tech.

To replace ISP router

Brought this recently to replace Huawei HG659 router from Vodafone. So far so good. It is faster, but I was more concerned with stability of WIFI network and range and it hasn't disappointed so far.
One problem I didn't foresee was that I have a home phone through DSL, of which this router does not have a DSL connection. I think I have found a way around this problem, which I will probably sort out in the next few days (using old modem as a switch - hopefully google hasn't lead me astray there).

Best router ever

Excellent router pretty strong signal for our 2 storey house. We have UFB and this router is able to transfer 100Mbps/20Mbps easy. Set up was basic. There are some other features which i haven't fully utilised yet. Overall I highly recommend this router.
