From the Manufacturer

Modern Design. Exceptional Speed. Versatile Innovation.

Wireless N Surfing, Scanning, and Printing All with One Router

Impossibly thin with a glossy black patterned finish, the ASUS Dual Band gigabit wireless-N RT-N56U router truly cuts the edge of innovation with powerful features that deliver the latest in networking capabilities. Equipped with exceptional hardware Network Address Translation (NAT), this one-of-a-kind router delivers up to 1000Mbps throughput that’s up to five times faster than conventional gigabit routers. The RT-N56U is like having two routers in one. Dual band transmissions enable both 2.4GHz and 5GHz spectrums simultaneously to give you faster, more secure connections. And with up to 300,000 sessions—20 times the amount of conventional routers—you have sufficient headroom for additional clients and devices without buying an additional router.

The RT-N56U also provides users with incredible versatility. Plugging in a USB All-in-One printer, enables easy sharing between printer and scanner functions for all networked PCs. Download Master BitTorrent client shifts download duties from the PC directly to the router-attached storage via the two onboard USB ports. For even more convenience, ASUS AiDisk transforms a connected USB device into an FTP server for remote transfers. The RT-N56U was designed with ease-of use in mind. With a CD-free, plug-and-play setup, the RT-N56U gets you up and running to let you effortlessly optimize bandwidth for gaming, video calls, downloading or whatever else you choose.

Whether you use it as a print server, BitTorrent hub, FTP storage, or ultra-fast Wireless N router, the RT-N56U adapts to your networking needs as a cross-functional network device.

Named the world's fastest router by SmallNetBuilder.

And where other routers fail to connect when placed far away, the RT-N56U router gives you the wireless freedom to roam even further and enjoy high-speed networking nearly anywhere in your home or office. Get bandwidth on demand with EZ Quality of Service (EZQoS). EZQoS dynamically sets Internet bandwidth priority for browsing, online games, Internet applications (such as BitTorrent), and voice/video streaming.

The Ultra Versatile Download Master

The RT-N56U router sets itself apart from ordinary routers by offering BitTorrent and FTP server functionality.


Share your movies, music, games, and other files. The included Download Master application utilizes the BitTorrent P2P protocol to download and seed Torrents to and from the connected USB storage device. What’s more, you can shut off your PC after setting up a torrent file to continue the download, PC-free. Download Master also lets you customize how you choose to share with custom bandwidth allocation when seeding.


Create your own personal FTP Server with ASUS AiDisk located within the EZ UI, and upload or download files from the connected USB storage device to any Internet-accessible PCs. Perfect when you forget documents at home or when sharing large files, FTP access grants you the ability to safely secure and access your treasured data through your router.

This is one of the best products money can buy.
James T. Engle, Jr.
This router drops internet signal at random times throughout the day, have to try to reboot to fix the problem, and sometimes it doesn't even work.
The user interface is very well made and it's pretty easy to set up.

We are a heavy intenet using famiily. If we aren't streaming Netflix or Roku, we have phones and computers all competing for bandwidth. I tried the new Linksys e4200, it was OK until too many people logged on wirelessly and started hogging bandwidth. The e4200 would really drop down in speed while it tried to deal with all of the wireless activity. So, I tried the WNDR3700 (v.98 firmware) The WNDR3700 has a fast processor and can handle a lot of wired and wireless users simultaneously. But, the WNDR3700 seemed to "hang" about once an hour for reasons unknown. When I say "hang", it might take 5 seconds to load a web page instead of the usually instantaneous load speed. It got a little annoying.

So, I picked up the ASUS RT-N56U router after reading all the reviews and tests on smallnetbuilder dot com. I have to say that this router is ridiculously fast (at least twice as fast as the WNDR3700) and has better reception throughout my entire house. In a location that I used to max out at about 7MB/s with the WNDR3700. I can now sustain 31MB/s in the same location. I have pretty much- 5 bars of wireless reception where I used to have 2 or 3 bars.

The ASUS RT-N56U is pretty easy to set up and I like the physical appearance too. Throw in the fact that it is smokin' fast and has great coverage and I think I got a heck of a deal for $127.

Highly recommended.

by the way, I just noticed that another reviewer was having problems with iPhones not connecting. Our iPhone 3GS, iPhone 4, iPad, and Android phones are logging on fine, no issues.

*** UPDATE 3/28/11 So far, the RT-N56U is performing perfectly and all DD-WRT bridges are connecting at highest rate. I am running firmware
I tried to update to the beta 7.0.1.

I have been in the market for an 802.11n router, and after having done some extensive research (as of April 1, 2011), I decided to go with Asus RT-N56U.

I can attest to the Asus RT-N56U being an excellent consumer-grade router even though it obviously falls short when it comes to more advanced enterprise-level features (where Cisco shines), which 99.9% of all users will never need or even know about. One of the excellent features of the Asus RT-N56U router (not often mentioned) is the fact that you can switch it to the AP (Access Point) mode. When Asus RT-N56U is switched to the AP mode, its WAN port becomes a switch port just like the other 4 LAN ports. You can utilize the WAN port to connect Asus RT-N56U to an external router, and thus not lose one LAN port for this. Therefore, when switching the Asus RT-N56U router to the AP mode, you retain all four LAN ports for the wired connectivity to other non-Wi-Fi devices at 1 Gbps each.

Asus RT-N56U supports concurrent 2.4 GHz and 5 GHz radios and the combined throughput via the back plane close to 800 Mbps (per the review by smallnetbuilder.com). In my personal test comparing Asus RT-N56U (in the AP mode) with the Cisco 1131 a/g Access Point, Asus provides nearly the same range in the 5 GHz band that the Cisco 1131 provides in the 2.4 GHz band. Asus RT-N56U 2.4GHz-band range extends beyond the Cisco 1131's range in the 2.4 GHz band. The Asus RT-N56U 5GHz-band range extends far beyond the Cisco 1131's 5GHz-band range.

As for the connection download speed, I was able to get almost twice the download speed when connecting wirelessly via the Asus RT-N56U (in the AP mode) vs connecting wirelessly via the Cisco 1131a/g AP. The numbers were as follows: 11.8 Mbps via Cisco 1131 vs 19.6 Mbps via Asus RT-N56U.

I recently purchased two other routers before purchasing this one to replace an older 2.4ghz router. The first router I purchased was the newly released Cisco Linksys E4200. I ended up returning it because I barely had a signal downstairs and slow output. My previous router usually had around 70%-80% signal downstairs however the E4200 would quickly lose signal the farther I moved away from the router. I purchased as a replacement the highly rated Netgear WNDR3700. This router had much better signal however it would not work with my external hard drive. Per review of online comments and Netgear's own website, the 3700 has issues being compatible with numerous external hard drives. Netgear has posted on their website about a dozen compatible hard drives that work with the 3700. I had the choice to either keep the 3700 and fork out another $50-$100 on a new external hard drive that would work or purchase another router with similar features. I ran across the Asus at my local electronic store. I never heard of this model before since it is a new release. Before I decided to purchase it, I went home and read the limited reviews I could find on it. Both expert and consumer reviews were positive. I ended up purchasing the Asus. I was completely blown away by the features and performance of this router. I have over 90% signal downstairs. My laptop is maintaining 230-270mbps connection when I am downstairs (about 30 feet away from router which is upstairs) which was impossible with both the E4200 and 3700. The user interface provides significant amount more custom options than both the Netgear and Cisco. My external HDD (Seagate) was instantly recognized by the router. I also found the wired connection runs smoother and faster than the 3700. The 3700 had a delay at times loading pages.Read more ›
