Dual-band connectivity for lag-free entertainment

Delivering 2.4GHz and 5GHz concurrent bands at up to 450Mbps and 1300Mbps, respectively, the RT-AC66U B1 has a total speed of up to 1750Mbps. You can perform basic tasks like web browsing and file downloading on the 2.4GHz band, while simultaneously allowing multiple devices to stream in HD or support online gaming and other demanding applications smoothly on the clearer 5GHz band.

ASUS

Do more at once with dual-core processors inside

The ASUS RT-AC66U B1 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.

ASUS

Entertainment everywhere, on every device

Exclusive ultra-sensitive receivers give improved mid- and long-range Wi-Fi signal, with high-powered amplifiers and AiRadar beamforming to deliver unrivaled coverage that's fast, reliable and stable for all your connected devices, from PCs and mobile devices to game consoles and beyond.

ASUS

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-AC66U B1 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-AC66U B1 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.

Your advanced security gateway

AiProtection, incorporating state-of-the-art, three-pronged security from Trend Micro™, provides advanced parental controls, blocks malicious addresses and intrusions for your PC or device, and alerts you if an infected device is connected. Potential weaknesses such as password strength and operating system vulnerabilities are also monitored at all times. Moreover, AiProtection even protects Wi-Fi devices without an installable security program such as smart TVs, game consoles, and smart home devices, giving you peace of mind.

Works ok, but...sorros

Pros: Works ok

Cons: Slow delivery fro Newegg, the five to seven day delivery took 11 days' but the worst is yet to come
I am not all that computer network literate. The included instructions were not complete, concise, user friendly or intuitive. So, I made a call to the Asus for help setting the router up. That was a waist of time. The call lasted maybe five minutes. Two to three of those minutes I was on hold. Then I was told it was my computer that was not working properly. This router was ordered to replace an Asus router that was acting up, after less than two years. I then called my ISP tech support, and he walked me through setting the router up, even though it is a brand they don't support. Imagine that.
No way will I ever buy from Asus again.

Other Thoughts: I cannot recommend this product to other people.
The Tech support I received was useless.

an oldy but a goody

Pros: paid $200 for it when it first hit the market a few years back. added 7 db after market antennas. it's still giving me strong whole house wifi in a 2800 sq ft 3 story building. beautiful highly programmable user interface. running multiple PC's. tablets and a smart TV running Hulu and fire TV without a problem.

Cons: none, solid device.

Other Thoughts: I'd like a $100. refund now that it's being sold for $99.

Awesome Router

Pros: + Easy to Set up
+ Good GUI (albeit a bit slow)
+ Great coverage / speed
I have owned this for quite a few years now. My ISP just provided me with a "New" Hitron Wireless Router, and I did a bake-off". The Asus won hands down.

Cons: - Range into the basement for the PS4 (Wireline Connection fixed this).
- Range into the backyard

Other Thoughts: I would buy this again.

Great features

Pros: Easy setup. Download the app and you can easily make changes.

Cons: Put this unit and the cable modem in a small closet and they do generate some heat. This has not caused problems but we did install a fan.

Other Thoughts: We have had this router in use for almost 2 years and we recommend this unit.

Great Router With Asus and some (but only some) open source firmware (Be warned).

Pros: Wonderful performance with Asus stock firmware, and Merlin and dd-wrt opensouce firmware.
A vast performance improvement over my RT-N66u's. For this reason I have bought 2 of these to replace my RT-N66u's.
The Legendary Asus Rescue mode makes it possible to try different firmware without fear of bricking the router.

Cons: Does not currently run My favorites, tomato toastman, shibby or their successor freshtomato.
The naming of the router model is very confusing.
Model Name: ASUS RT-AC66U B1
Hardware Version: HW B2.
Apparently HW B1 would run tomato shibby and toastman firmware for the Asus RT-AC68u, but the HW B2 is trickier by far.

Slow to boot compared with my old venerable RT-N66u, but this is forgivable given the wonderful performance.

Other Thoughts: Here is how I got the opensource firmware to run.
NB In all cases one must flash for the RT-AC68u !!!!!!!! (not 66u)
(1) Merlin: I used RT-AC68U_384.6_0 dated 2018-07-25.
(2) dd-wrt: I used asus_rt-ac68u-firmware.trx 2018-08-22 25,27 MB
The 5GHZ led did not light, but the 5GHZ itself was working after the 2GHZ light came on.

Good w flaws

Pros: Pretty much has every setting you would need for advanced router set up. I flashed w Merlin right away. Port forwarding is a breeze. AI protection is a benefit. Over all I'm ok with it.
But see cons.

Cons: Gui is extremely slow. Making changes to anything advanced is a 2- 6 minute reboot. CPU gets over taxed. Found the 5 ghz to be weaker than my old rtac66. Also effects network speed.
Very surprised that the 66 does better.

Other Thoughts: I have many devices on my network. Maybe to much for this router. I also use the asus ddns.
It's slow. Still looking for optimal settings for this after six months.
PS. Buy a cheap laptop cooler. Keep it cool or otherwise...reboots.
