Product Description

Product Description

Dual-band for Lag-free Entertainment

The stylish ASUS RT-N56U is an advanced wireless router combining a series of cutting-edge and powerful technologies to offer users an ideal internet and wireless package. Users can double their wireless performance and bandwidth with simultaneous 2.4GHz and 5GHz bands and speed up to 600Mbps combined. While basic internet applications such as browsing or file downloading can occur in 2.4GHz, wireless HD content streaming takes place in the 5GHz band so you can enjoy smooth, buffer-free entertainment.

Ai Radar Optimized and Reliable Wireless Coverage

This unique and efficient design drastically increases wireless signal coverage and quality without increasing power consumption. Ai Radar intelligently adapts beam patterns to local conditions to enable higher-gain / signal strength. Ai Radar shapes signals to offer the strongest possible output, transforming what may be a weak signal to a stronger unidirectional one, improving throughput at same time. Traditional routers blast beam patterns everywhere which leads to signal loss. The ASUS RT-N56U locks in on each wireless devices to provide dedicated and stable signals.

Multi-Function Twin USB Ports

With effortless connectivity to a range of devices, FTP, SAMBA, UPnP AV server and DLNA all supported, sharing and networking has become easier than ever. Additionally, the RT-N56U can continue downloading FTTP, FTP and BitTorrent files to the USB disk all day even when your PC is turned off! Furthermore, twin USB ports allow the router to offer printer and file server functions, so users can enjoy simultaneous wireless printing, scanning and file sharing via the comfort of standardised USB!

Powerful Online Multitasking at up to 300,000 Data Sessions

The ASUS RT-N56U provides support for a massive data pipeline of up to 300,000 data sessions, meaning that the RT-N56U has around 20 times the networking capacity of other high-session routers. This high capacity ensures that multiple data transfer jobs don't slow down even during a heavy load.

5.0 out of 5 stars Does not have ADSL modem included 23 April 2012
Verified Purchase
When you search for ADSL modem, ADSL router etc. on Amazon, this device comes up but PLEASE note this router doesn't include a modem - you will need to get a separate bridging modem to go with this. Amazon really need to update the search so idiots like me don't get so easily fooled. The silly thing is I had even read/watched many reviews of this router and it wasn't mentioned once. So remember, if you want this bit of kit add a bridging modem to your order!

5.0 out of 5 stars Hasn't Let Me Down... Yet 28 Nov 2011
The first thing you want to do when you get the router is to set up wireless security settings of "WPA2 Personal" and enter your own password into the "WPA-PSK Key" box to avoid potential interlopers from simply accessing the unprotected router and changing settings at will for their own nefarious purposes.

NOTE: you need to change wireless security settings for BOTH the 2.4GHz and 5GHz tabs to secure the router, as they use separate settings.

To access the router's web interface after connecting to it either via ethernet or wireless one needs to type in the address bar of a browser:

and enter the default username and password of:


To get this router working with my Virgin Media cable I had to switch the MODEM off and then on again. It wouldn't automatically work by using the "Quick Internet Setup" button in the router's settings without power cycling the MODEM. This is a minor problem, as it only took me around 10-20 seconds to perform the reset, and it may not happen to you. After that, I could browse the web straight away.

Once I had determined that I could connect to the internet perfectly fine, I visited the official ASUS site to upgrade the firmware of the router (which at the time of writing is As I apparently cannot post links in Amazon reviews, no matter how innocent they may be, you can find the firmware update by typing "ASUS RT-N56U" into Google, clicking the first result and then the "Download" tab. Extract the downloaded archive to a directory of your choice and then enter the router's configuration page and click the "Advanced Setting" button, "Administration", "Firmware Upgrade" tab. Then click the "Browse..." button next to the box labeled "New Firmware File".

5.0 out of 5 stars Fantastic router 3 Nov 2011
Verified Purchase
I live in a flat which, thankfully, has very well built walls, which is of course desireable. The only issue is, inevitably, wireless reception.

I wanted a router to replace a DIR615 connected to my VM Superhub, which can not only provide a strong signal throughout, but also be able to handle multiple devices (at last count, I have 15+ devices connected through gigabit/WLAN, from my Panasonic VT30 to ReadyNas to Sonos) with no sweat. I put the Asus in router mode, and put the superhub in Modem mode. It picked up my configuration instantly and I was up and running with basics working within a few minutes.

You have to understand that when you buy a router like this, you have to step in and configure it to get the best out of it. I had issues where my Sonos would not bridge the other zones correctly, which was resolved when I changed the router IP to

So far, the router has been fantastic. 2.4ghz signal remains full throughout the flat, even in areas the DIR-615 was barely 1 bar. All our devices work perfectly (iPads, laptops, SGS2, iPhone 4S) with no dropouts as we had before. I have also noticed an increase in transfer speeds between my ReadyNas and PC, as well as a nominal increase in NTP transfer speeds (perhaps as a result of using better routing in the Asus than Superhub)

I personally don't mind the interface, though some items took a bit of digging around to find. The only issue is the 5ghz signal is weak, though AI Radar I presume has been retweaking the signal, as it is slowly getting stronger. This is not an issue as all devices I want to use 5ghz are within a good range.

All in all, a great looking router, and works great.

5.0 out of 5 stars excellent worth every penny 5 Jun 2012
By ste
Verified Purchase
I bought this router because the virgin 'superhub' gave me terrible performance on a 100mb connection After looking around at various review sites I decided on the Asus RT N56u and can say wholeheartedly it's one of the best purchases I've ever made!
The connection is flawless in any room in my house; I get at least 75mb EVERYWHERE upstairs or downstairs, or outside.my wireless top speed is 107mb The router is easy to set up simply plug the router into your cable modem and then connect an ethernet cable to a computer either Mac or Windows and follow the setup wizard that automatically is displayed by your web browser. The Router allows for two different frequencies either 2.4 or 5ghz simultaneously
This router suits all your possible needs; if you're a heavy downloader or you watch a lot of HD streams or If your a gamer looking for a router that's going to give you a lag free experience I can say from my experience this is the router for you,
some of the features includes the ability to optimize your network experience for a particular activity; either gaming, ftp, HD streaming and Email + Web. It also displays all the connected devices with a possibility to either block one and even prioritize which device you wish to have a better share of the network.

All in all I can say this is the perfect router
