It is very nice. The setup was bothersome because to access the router via a browser I had to use an IP that I've never used before and nowhere in any booklet or on the router itself was there an explanation to this, I had to google for a good hour or two before I realized this awkward IP address...

I was able to price match this router with another vendor and was pleased with the 110% match. Before the price match this router is actually too expensive for what it is listed at. The router performs very well - and provides much greater coverage than the ISP standard router we had before.

Bought the router last Feb,2013, wouldn't connect to ISP this AM, went to ASUS web site their solution return to where I bought it, almost 200 bucks down the drain

Asus introduces its pre-draft 802.11AC router: the RT-AC66U. It's the only pre-draft 11AC router so far, to utilize external antennas, a plus for range, because the RT-AC66U sustained the best throughput at distance than any other pre-draft 11AC routers tested to date.

Excellent range; Top performing router at 5 GHz N, very good in 11ac mode; Advanced features; Business-class capabilities

Some sluggish performance in the interface; Connected clients lost Internet connectivity a few times

NICE JOB ASUS KEEP UP THE GREAT WORK?

Let me tell you if you want the best out right now this is it; In combination with the N66 you can go 4 houses down and not loose bandwidth; I am a 50 years old and I worked for

Nothing wrong it is the perfect home networking setup

It's one of the best wireless that I've ever owned. Highly recommend for office users.

Great Quality for an Asus & great security features too; Fast Wireless Router

Asus has introduced its pre-draft 802.11ac router, the RT-AC66U. It's the only pre-draft 11ac router thus far to utilise external antennas, which is a plus in terms of range, and the RT-AC66U sustained a better throughput at distance compared to other pre-draft 11ac routers we've seen.

Very impressive range; Excellent performance at 5GHz 11n; Plenty of advanced features on board; Business-class capabilities

Somewhat sluggish interface; Lost Internet connectivity a few times

This is Asus' first 802.11ac wireless router. While Asus is primarily known for its laptops, tablets and smartphones the company has also been carving out a niche for itself in the router market.

The fastest wireless ac router yet; Excellent 802.11n speed and range; Intuitive user interface; Fast; simple setup and management

No USB 3.0 ports; Lacks true Cloud platform of D-Link/Linksys; Design not the most subtle

My frustration with this product is entirely based on the absolutely inadequate instructions included with the product, to allow me to restart the router after installation fails (and it seems like it always does!).

Don't buy unless you are willing to junk it when it stops working--product became unusable after 6 months and it is impossible to reach their tech support (I have wasted hours trying to reach).

Initially (when it worked) high speed; even when not using AC protocol; Good software interface

Wireless became highly unstable, dropping devices and/or not letting them connect, after 6 months; After 9 months, wireless did not work at all; TECH SUPPORT IS WORTHLESS--they do not answer; DO NOT BUY FROM ASUS, WHICH DOES NOT SUPPORT USERS
