    Stylish looks and great performance! Can we call this 'Dark Knight Rises'?
    Update (10/1/12):I downgraded the firmware back to 164. Since I upgraded the firmware to 220, I have already rebooted the router about 4~5x, the internet connection suddenly stops. I don't know if it's just me, but I feel that the router is a bit warmer when I touch it using firmware 220. I don't have any temperature measuring device so I can't confirm that it's really warmer (I did not adjust the transmit power setting, fyi).Update (9/12/12):I updated the firmware to version 3.0.0.4.220, and the 2 previous problems I stated is still existing.. I don't mind it that much but I still hope Asus fixes it soon. Workaround for 1.) I connect my PC to 2.4Ghz. 2.) I use Splashtop from my iPhone to connect to my home PC from office.AiCloud looks promising, supposedly you could view/play your media files from your iphone/ipad and android devices within and outside your network. But I'm stuck with the loading page, after I put my login user and password. My iphone can't login. Can anyone confirm if the aicloud works?Update (8/30/12):So far have encountered 2 problems with the latest firmware (3.0.0.4.164)1. I'm using Nero Media Home 4 in my PC to share my media to my wireless TV, Bluray and PS3. When my PC is connected to 5Ghz, the tv, bluray and ps3 cannot connect to Nero. When I connect to 2.4Ghz, they can see Nero and play the media. This works fine with N66U.2. I have setup port forwarding for Remote Desktop Connection, so I can connect to my home PC from my office. It's not working. This again, is working fine with N66U.QOS is also a known problem, but I'm not using it for now. I believe it's just a firmware issue since both are working with N66U. I hope it gets fixed with the next firmware release.Original Review:I bought this to share my media files, from an external hard drive, to my 3d tv and wireless bluray in bedroom. So far I'm not disappointed. I also have N66U to compare with, I've read from other reviewers that this router gets hot, when I touch the top part, it is warm but not hot, which is the same with my N66U.This is suppose to have a greater coverage compare to N66, but to my experience, the coverage is the same, which is already awesome.Initial setup was very straightforward, easy, fast and CD-less. Below are the actual steps after opening the box:1. Connect LAN cable from modem, LAN cable going to PC, and power cable2. Open web browser. Router setup page automatically shows up. Click Next3. Type the User login and Password that you want. Click Next4. Type the SSID and key for 2.4Ghz and 5Ghz (or you can click the checkbox: Copy 2.4Ghz settings to 5Ghz settings). Click Apply.After that, your wireless device should now be able to connect to your new router. I even used the same SSID and password from my previous router, and my devices connected automatically after the setup.These are my devices that connects to this router:- 3 laptops- 2 Iphones- Ipad- wireless tv- wireless bluray- PS3- wireless printerNo problem with connections, no disconnects, iphones when outside the apartment are still connected.PROS- Media Bridge mode. Applicable using 2 AC66U. This feature is not available to N66U- Dual band, 450Mbps+1300Mbps. I can't comment with the AC speeds, I don't have wireless AC clients for now.- HTTPS authentication when accessing admin page. If your using this for office/business use, this is plus.- AiCloud. Coming soon, the app is not yet available from the appstore/googleplay as of this review. (This is now available as of firmware version 3.0.0.4.220)- 2 USB ports. Supports external hard drives, printers or 3g/4g modems- 3TB external harddrive works (Manual says only up to 2TB is supported). Tested using Seagate expansion 3TB STBV3000100. My TVs won't even accept 3TB harddrives when connected directly to its usb ports.- DHCP Manual IP assignment (if you need static private IP on your device)- DLNA. Streams HD vids, pics and 3D vids to my LG tv and my LG bluray player, no lags, no disconnects. And this is even using wireless connection and not wired.- Awesome range. Before, I was using a cheap netgear, single band 2.4Ghz, included from my ISP. From the farthest point in my apartment, I get 2 bars of signal in windows 7 wireless network connection settings. With AC66U, I get full 5 bars using 2.4Ghz, and 4 bars on the 5Ghz band.- 3 Large external antennas- Download Master (if your into P2P downloading/uploading)- Option to vertically stand the router, or wall mount- User friendly setup- Impressive performance particularly on 5Ghz band- Stylish looks and superb quality- Ability to install 3rd party firmwaresCONS- Steep price (but worth it!)- Lack of USB 3.0 (not a big deal, since I don't get usb 2.0 speeds for file transfer using FTP or Samba, which I already know before purchasing this)- Manual is a bit helpful, but this router has tons of features and the manual only mentions the basic functionalities.If you got the money, and want a great performing router and stylish as well, I Highly Recommend Asus RT-AC66U. If you're about to buy N66U, just add $20~30 to your budget, and get this router, you won't regret.

    Reviewed in the United States on February 2, 2014
    Size: NewStyle: RT-AC66U (AC1750)Verified Purchase
    I have owned this product for > 6 months at the time of writing this review.

    To start, I am fairly knowledgable (through experience) on setting up networks. I had (and still have) a Netgear N300 (WNR3500L) that I received for free through the SamKnows program. If you're not familiar, that is an organization that reports ISP performance to the FCC, grades it if you will. Anyway, it replaced my old Linksys (which I also still have, and which was running open-source firmware). I was happy with the Netgear's performance but noticed slowly that the 2.4Ghz spectrum was getting crowded around where I live, and that the range was not as good as I liked (this being used in a 2 story old 1950s home). Still for free, the router was great.

    Eventually I really needed better wi-fi range. I also realized I had many products that could utilize the 5Ghz band. (And later, by late 2013, I had more than a few devices which could utilize 802.11ac). After much research I settled upon this router. It had good reviews, and I also really like the ASUS brand based on other devices I had used (motherboards, the Nexus 7 2012 and 2013).
    ------------------------------------------
    Setup was painless. I did it twice, let me explain why:

    First setup was your traditional setup, router to your ISP's modem, in this case my Comcast modem. You plug in your computer directly to this device's ethernet port (ports 1-4), and have it plugged in and powered on. It'll give your computer an IP address, get on a browser and it'll automatically re-direct to the built-in setup pages. I simply followed the instructions and I was up and running. At some point during setup it had asked me to connect the router to the Comcast modem, and I set the MAC address for Comcast that I know works (further explained below), and I was up and running.

    (The MAC thing)
    Now for anyone not familiar, some ISPs (including Comcast, at least here in Chicago) "imprint" on the MAC address of the device you activated your Comcast connection with. Basically every device that can connect to a network has its own MAC address, it's like the device's social security number, something unique to identify the device with. So I first activated my service long ago with an old laptop, and I had saved the MAC address I used, let's pretend it was "ABC". From there on, I knew anytime I needed to connect something to the Comcast modem, the device's MAC address needed to be "ABC." Now I know I just said MAC addresses are unique, but you can also manually set a device's MAC address. So when I had my old Netgear connected to the Comcast modem, it's MAC address was set to ABC, and now that I connected the ASUS, I needed to change it's MAC to be the same. Failure to do so would mean your connection to Comcast will intermittently but reliably drop, slow down, etc.

    So why the second setup? Well I was happy with my setup but after a few weeks I realized that without having my SamKnows router connected, the organization couldn't collect and grade my ISP. So I had to re-arrange my network.

    I went from: INTERNET > Comcast Modem > this ASUS router > all of the devices in my home
    to this: INTERNET > Comcast Modem > Netgear router > this ASUS router > all of the devices in my home

    And I could've actually left the setup the way it was but I chose to switch this router from the standard "Wireless Router Mode" to the "Access Point mode" which means it basically serves as a traffic manager, and the actual IP addresses are given out by the Netgear router.
    ------------------------------------------
    I turned off the Netgear router's wi-fi radio. Nothing is connected via ethernet to my router(s). Everything is wireless and it all goes through this ASUS. How many things? Well in a house with 6, many!

    Devices connected wirelessly to this ASUS at all times:
    - Computers: 2 Macs, 4 PCs
    - Tablets: 3 (an iPad, an iPad mini, and a Nexus 7 2013)
    - Phones: 6 (or more) including a Lumia 920, iPhone, Galaxy S2 and Galaxy S4, a Nexus 5, a Moto X
    Others:
    - Wireless Print Server by Linksys
    - Wireless printer/fax by Brother
    - 2x Roku 2 XS devices (used mainly for Amazon VoD, Netflix, international IPTV channels)
    - 2x Chromecast devices (used mainly for Netflix, Google Play Movies and Music)
    - Receiver for our 5.1 setup
    - Video Game systems: Xbox 360, Nintendo Wii
    - 2 Bluray players (Sony, Panasonic)
    - visitor's laptops, phones on occasion

    That's all I can remember off the top of my head. As you can see the list is long but probably not too different from many typical households.

    Except for 1 Roku and the Brother print/fax, all of those devices are in a different room from the router. (Even the tablets and phones). Half of the devices (including one Mac, the Moto X, the Nexus 5, the Xbox and Wii, the receiver) are in the basement, and not just below the router but a good 20-30 feet East or West of the router.

    Yet performance never suffers. Comcast gives me just about 50Mbps if I check a computer connected via ethernet to the Comcast modem. With this ASUS router I typically receive 40-50Mbps when I'm on the same floor or below the router, and about 30-40 Mbps when I'm 2 or more rooms away. That's both the 2.4Ghz and 5Ghz (though typically the 5Ghz is faster). It also depends on which device I'm testing though, because the Mac Pro can get 50Mbps even when it's on another floor and as far away from the router as possible. Essentially, I suffer little or no loss in performance going through 2 routers with the last step the ASUS wireless antennas.

    On any given day there could be, simultaneously, one person using Chromecast to watch Netflix, another using the Roku for Amazon VoD, multiple people browsing on their computer/tablet/phone, and not one person is complaining. I get that this is partially due to the bandwith my ISP gives me but my point is this router isn't choking on the performance I'm paying my ISP for, it actually delivers it to the end users.

    The range extends far outdoors too. I can shovel the snow and continue streaming music on my phone with Google Play or Pandora, and not have to use my cellular connection.
    ------------------------------------------
    Features are good too. When I switched to the Netgear, I missed my Linksys because I could run open source firmware on it but this has a lot of the features I would want already.

    - switching router modes is easy, as you saw above; in addition to the router mode, AP mode, there is also a wireless repeating mode and a "media" mode for which ideally you'd have 2 of these, and they would talk to each other over 802.11ac, and the 2nd would then have ethernet connections to your Xbox or some other "media" device, this way you can wireless transmit a FAST connection
    - Guest network with 2.4/5Ghz support, the guest network will allow people access to the internet but not the intranet (so my devices are safe from nosy visitors)
    - once you have your router setup the way you want (for example, I need it in AP mode, I have 2 wireless networks broadcasting with different SSIDs and a guest network, I have certain MACs getting specific IPs, etc.) you can SAVE your configuration so that if you ever for some reason needed to do a factory reset or someone changes settings and screws things up, you can "restore" to your personal settings with that file
    - upgrading firmware is easy
    - you can enable/disable specific radios (2.4Ghz, 5Ghz), you can have it set so that the 5Ghz radio is only active on weekends or on Mondays and Tues, or whatever you want! -- you can adjust the broadcast power output of the signal! (these are things that were previously only available if you installed custom firmware on older routers)
    - 2 USB 2.0 ports.. of course now I wish this was USB 3.0 but to be honest I will never use these ports for storage (I use Google Drive) -- but the COOL thing is that you can use these ports as a way of providing 3G/4G access as the "source" internet for the router .. so let's pretend Comcast is down but you want to use your phone (or you have a USB dongle) and you want to share your 3G/4G internet to the whole house .. this router will let you do that as a "backup" option
    - it has print server capabilities, again via USB ports
    - links on every page in the GUI to the router's support page, router's manual page and router's utilities page
    - can quickly/easily switch the language, if that's your thing

    There are many more features, which I don't use or maybe don't even know about.

    So setup is easy. Performance is great. Features are extensive. I also think the thing looks very cool. I highly recommend this router.

    "It Just Works", this should be a new technical certification, and this router passes!

    Simple hookup, simple setup through your browser, and bam!!! I have a greatly increased coverage area with much higher throughputs throughout my property.

    Bedroom above the router was at 5Mbps, now at 32Mbps, kitchen was less than 5, now at 26. Coverage extends to the garage and back of the yard when I had no coverage at all. One bedroom was the bermuda triangle, a deadspot so bad that even my extender outside the bedroom didn't help, now my wife can use her computer there and watch Netflix on the wireless media player while on her eliptical. No need for powerline ethernet now!

    The web interface is well thought out and very intuitive. The only issue I had was that UPNP did not automatically open up my ports for my Go-Flex Network Attached Storage so that I can access it away from home. Rather than using a cloud service I stream my my music and movies from my Go-Flex while away from home.

    Router also serves as a DLNA and Itunes server and has several additional features such as cloud, USB sharing and remote downloads. I'm not using any of these, and if you are using a network attached storage device you cannot utilize with these services which seems like an oversight, only USB attached storage can serve as your Itunes storage.

    I like the ability to set time restrictions on my daughters devices so that she's not using them after bedtime.

    You can use a 3G/4G USB dongle as a backup if you lose your service provider, or if 4G is what you use primarily; I haven't tried this and am not sure of any extra costs or if you can use with a sharing plan. Either way, it's sure to pull a lot of data down on your 4G plan which can be pricey.

    Has QOS (Quality of Service) but you need to be familiar with it as well as what and how to configure.

    I LOVE being able to adjust the power settings for both bands individually, this really helped provide better coverage.

    The unit is good looking and comes with a stand meant to stand it vertically. I used mine backwards to provide it with a sloped profile, providing air underneath for cooling but keeping the profile low and the antennas where I wanted them.

    What I would improve:
    The ability to give MAC IDs nicknames, in several areas, such as setting static IP Addresses you can only view the MAC address. I keep two windows open when setting these so I can refer to the device name if it's displaying one or the current IP address. UPDATE 9/2/2014 - ASUS has released an update that allows you to give MAC Addresses nicknames, this makes managing devices and assigning Static IP addresses a breeze! Many thanks to ASUS for listening to their customers!

    I would allow the same connectivity as USB devices to Network Attached Devices such as hard drives to give them the same utility.

    Wifi attached printers should have the same utility as a USB attached printer, this would simplify setup for some wifi printer users. (some would say that this may be a bit superfluous but not everyone is tech savvy and getting these kind of devices set up can be a pain).

    UPNP should automatically configure port forwarding for other UPNP devices that need it (I had to add open and point the ports myself).

    QOS should be much simpler to set up, with the ASUS it's basically up to you to figure out what you need and how to configure it. Some simple questions such as "Are you a heavy internet gamer?", "Do you watch a lot of YouTube, Netflix, Hulu or other online video?", "Do you use VOIP, Skype, etc.?" and from these make the appropriate configuration; it's really not THAT hard.

    There are three additional Guest Networks for either band, each is highly configurable and can be time restricted for usage and access to your intranet.

    VPN server creates a private network to your home network from anywhere in the world at anytime.

    Firewall with URL, keyword and service restrictions.

    Various usage, system logs and network tools.

    IPV6 and Dual WAN ready.

    Have not found any user configurable settings for usage alerts or throttling based on usage (cap limits).

    Power user friendly, tons of advanced settings if you know what you are doing.

    Bottom Line:
    This router rocks, in terms of simplicity and just working I am VERY satisfied and would not hesitate to buy another. Easy and intuitive interface, strong coverage, high throughput. I would recommend this as a great router for home and especially for a small business.

    I love ASUS products and have never been let down by one yet.
    UPDATE 9/12/2014 - I've had this router for almost a year now, and it's still the most reliable and the best performing router I've ever had to pleasure to work with!

    Il router e' arrivato con OS Asuswrt-Merlin, fantastico. Collegato in modalita' dualWan con chiavetta 4G Huawei E3372 , funziona perfettamente in failover. Anche le OpenVpn sono perfette. La VPN e' stata realizzata tra questo router ed un appliance pfSense. In precedenza era stato acquistato un altro router sempre Asus, RT-AC1200GPlus , che ho reso in quanto scarsissimo. Questo.... e' un altro pianeta...

    Me gusto que el alcance es muy bueno cubriendo un local comercial en su totalidad de 120 m2 (Esto me implico ahorro en repetidores)
    Las opciones de configuración son amplias, tengo activas 3 redes con distintos usos en el mismo dispositivo, con diferentes contraseñas, 1 a 2.5 GHz y otra de 5 GHz.
    Tiene base para colocar sobre pared pero con espacio para disipar el calor.
    Tiene una aplicación Android para cambiar las configuraciones del dispositivo casi en su totalidad siempre que estés dentro de la red y alcance del dispositivo.
    En mi caso las ocupo para cambiar la contraseña de la red Guest cada determinado tiempo y siempre es mas practico y rápido desde la APP
    La instalación iniciar es muy fácil y rápida ya que es intuitiva el software.

    Lo único negativo que puedo comentar del producto es que el precio es alto (Ojo No caro) solo alto por que otros Ruter de menor venor velocidad que igual carecen de menor alcance pueden valer 1/4 del precio pero en especificaciones técnicas solo le resta un 10 o un 15 %, a beses nos vamos con la finta de que el mas caro es mejor pero no siempre aplica ya que la calidad no se mide en potencia o especificaciones técnicas, un producto es de calidad cuando cumple con su propósito con e cual fue creado y satisface las necesidades del cliente.

    Mi concejo es compra este producto solo si requieres cubrir mas de 100 m2 o si requieres muy necesariamente de una red 5GHz de lo contrario Compra un router de menor costo que igual satisface tu necesidad.

    saludos.

    As always, Amazon delivered the correct, working product to me very quickly.

    I bought this router as the Modem+Wireless Router combo from my internet service provider had very poor wireless range and lacked the more advanced options like Quality of Service.

    When I disabled the wireless network on my Modem+Wireless Router combo and set the ASUS RT-AC66U up. The wireless range far exceeded my expectations and I have the option to push more power to it and extend the range further if I so desire.

    I would consider myself proficient with networking having set up about 20+ wireless networks for family and friends but by no means am I an expert. That being said, the setup wizard of this router was one of the easiest I have ever done. Someone with little to no experience with setting up a wireless network should be able to get this up and running. The homepage of the routers interface provides most of the essential information that is needed when wanting to change basic settings of the network and should suffice for most peoples needs. Where I was amazed with this router was when I got into the advanced settings. I have never seen a router with so many options to be able to customize every little detail to make the network exactly what you want.

    I’ve only ever had D-Link or Linksys (Cisco) routers in the past but reviews from multiple computer websites really sparked my interest in this Asus product. Thus far I’m very happy with the performance and features.

    Pros
    Wireless Range
    Easy Setup for basic network
    Advanced options are seemingly endless

    Cons
    I can’t think of any
