Great range and easy setup

Pros: Easy setup, though to be fair I was using an Asus router before this one so I am familiar with the interface. Great range on 5GHz reaches far enough that I turned off the 2.4Ghz wireless. Interface is fast to respond when making changes.

Update: I have been using this router for about 2.5 years now and it has been rock solid.

Cons: I have seen reports that if you use QoS the upload and download settings are reversed, I have not confirmed this. Be aware of this until it gets fixed.

Update: I believe the QoS problem has been fixed now.

Overall Review: Overall this is a great router upgrade for me coming from a RT-N16.

Works Great so far

Pros: -Really fast, with good range.
-Easy to use menu (once you figure out how to get logged into it)
-The phone app is handy too.

Cons: -Can't reliably access it with 192.168.1.1 in your web browser. You have to use the "router.asus.com/etc..." address. (which isn't really a problem once you figure it out... But it definitely slowed me down on first setup).

Overall Review: Hasn't had any hick-ups so far, so if it keeps running like this, I would recommend it.

Works great, until it doesn't

Pros: -Easy setup
-Good performance
-Highly configurable
-Price/value
-Decent warranty/customer service

Cons: -Unreliable
-Asus website is horrible

Overall Review: -No, I would not recommend this product.
-Profession: Software Engineer

Worked great out of the box. 2.4 GHZ band failed after about a year (super common for Asus routers, Google it). Could not successfully fill out the form for the RMA (website autocomplete is required and doesn't work). Had to call again, spent $15 to send the router back to Asus. Received a replacement router very quickly.

Replacement router failed the same way 3 months later. Starting the process again. This is not an uncommon issue for this product. Reviews are really positive for people who just purchased, I doubt many of them circle back to edit once the unit fails. I wish I had done more research before buying. I suspect I will be dealing with this until my warranty expires and then buying a new router within 6 months after that.

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.

Overall Review: 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.

Overall Review: 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

Overall Review: I would buy this again.
