Style Name: Model RT-AC66U Verified Purchase
(16 months later, update at bottom) I've been following routers for about a year and determined this model would help future proof some wireless stuff we purchase next year. It's also one of, if not the strongest available. I was a little intimidated buying this one because of all it's features and not one of the traditional router brand. I thought setup would be a hassle. Boy was I wrong on all counts. This thing is wonderfully thought out...in all areas. It blows away Cisco's new "cloud for dummies", tricking some into online router accounts, so they can track your data usage.

Before setup I found 3 excellent HD Youtube videos (ASUS RT-N66U Setup...Wired...Wireless). They're made by a down to earth Asus employee who does a great job covering the setup wizard and various features. Getting it up is a breeze, very simple, takes a couple minutes for both wired and wireless. Before install you might want to check into the following:

1) Download the latest firmware from the ASUS website. The routers FW version listed at top of GUI, nice! (Router access is
2) Decide if you want a different (SSID) name for the 2.4GHz and the 5GHZ channel and figure out what the names will be.
3) I used an online "WPA Key Generator" so the keys were ready before setup. I created a different one for each channel.
4) Visit smallnetbuilder.com forum for the AC66U. Read the couple threads on how they're getting strongest signals, best channels, frequency's, etc. Many passionate owners will help with timely support and tips.
5) Test your internet speeds and pingtest.net before - and after you install this new router.

The routers GUI is incredibly easy to understand and has tremendous amount of information and features.

Style Name: Model RT-AC66U Verified Purchase
First off, let me start by saying that this router isn't like the ones I have purchased in the past. I feel it is a enthusiast's router, but at the same time it is so much easier to setup even if you are a newbie. It took me just 1 minute to set this up and another minute to get it connected. If you are reading other reviews on here take them into consideration because this router is around 200 dollars.

Second, I am a student studying network administration and I don't know everything about Networking yet, but I am getting there.

Note: I will be updating this review to include a lot more when I have fooled around with it more.

This router not only met my needs, but it exceeded them. I logged in the router for the first time to find a plethora of amazing utilities and trust me when I say this "I wish Cisco would have their user interface on their routers like how Asus has it setup on this one. Its it remarkable how well they have polished the interface and make it so user friendly but at the same time giving us techies what we need.

The Specifics:
Connection: I get full bars and I have yet to go down the street to see if I still have a connection, but I will say this. My E1200 router would only give my mother that's on the other side of the house 3 bars. With this it is a max of 5 and her speeds are amazing when compared to the E1200's speeds.

Remember me saying Swiss Army Knife? Well this router has the following:
Guest network setup with 3 network keys for the 2.4ghz network and 3 network keys for the 5.0ghz network. Unheard of I say! Hats off to Asus for that.
Traffic manager is another nice add but one that is common place on every router out.

Style Name: Model RT-AC66U
Before having the great Asus RT-AC66U I was dealing with a Cisco E4200 v2 (Stay away from these routers). The Cisco E4200 v2 was a terrible product, it had an intermittent internet and slow speeds (I spent more than 1 hour with Cisco support trying configurations) then I gave Cisco another chance, I bought a Bran new Cisco EA4500, same problem impossible to get it to work properly. I did a lot of research and it looks like many many people are having these problems with Cisco and there is no fix. The 2 Cisco high end routers that I have tryed were really bad, dropping a poor signal on both 2.4 and 5.0 and really slow slow. Then I got the Netgear AC 1750 (R6000) It worked really well, but I didn't like that in the configuration you could not choose N or AC modes only, instead it says Up to 450 Mbps, Up to 1300 and like that so it enables all Wifi types and you can not use it as N only, apart from that it was so Bulky even the charger was large as the ones found in laptops.

I Just received the Asus RT-AC66U and it works great, excellent range and speed link (260Mb 10 meters -33 ft- away from the router, some walls in the middle) The Set up has easy options for novice and advanced tools for expert and it look really good. The router has the better construction quality that I have seen, the plastic, the terminals and everything looks really good quality (The Netgear looked so cheap from the outside, and the Cisco was just ok)Even the box was better quality and better printed that the Cisco and Netgear ones, also the manual. The router's look is great, like a jewelry box.
