ASUS RT-N56U overview

  • 1Description

The Dual Band Wireless-N Gigabit Router from Asus is a versatile, high-performance router designed to effectively work with a wide variety of wireless and wired devices on your network. This router can connect to your wireless N, B, and G devices and operates on both the 2.4GHz and 5GHz bands. Operating on dual bands at the same time allows you to experience optimal data transfer speeds, so that you experience little to no lag or interference. As such, each band can transfer data concurrently at up to 300Mbps. You can surf the Internet, send emails, or download files on the 2.4GHz band and stream multimedia content, such as HD video, music, or online games on the 5GHz band.

This router also utilizes a Gigabit Ethernet WAN port for connecting to your modem and features four Gigabit Ethernet LAN ports for establishing high-speed wired connections to any of your Ethernet-enabled devices. Beyond these ports, the router also has two USB 2.0 ports, which allow you to connect NAS storage devices or printers. With an easy-to-use interface, Asus's Ai Radar technology, and support for up to 300,000 data sessions, this router is a sure-shot way to brilliantly bring the Internet to your wired and wireless devices on your home or office network.

Dual-Band for Lag-Free Entertainment
Double your wireless performance and bandwidth with simultaneous 2.4GHz and 5GHz bands that can transfer data up to speeds of 300Mbps concurrently. While basic internet applications like browsing or file downloading can occur on the 2.4GHz band, wireless HD content streaming can take place on the 5GHz band at the same time. In turn, both bands allow you to optimize the speeds at which you surf the net on the one band and stream multimedia on the other band
Gigabit Internet Surfing with Hardware NAT
Equipped with a capable hardware NAT acceleration engine and built-in Gigabit Ethernet, this router gives you full Gigabit internet performance, making its WAN to LAN throughput up to 2-5 times greater than that of traditional software-based NAT Gigabit routers
Plug-n-Surf and Hassle-Free Management
ASUS EZ UI offers you an intuitive router setup without read manuals. What's more, you can enjoy simultaneous printing and scanning by connecting an all-in-one printer to the router via the USB port. Also connect external hard disks to enjoy instant file sharing with family and friends
Ai Radar Optimized and Reliable Wireless Coverage
This unique and efficient design drastically increases wireless signal coverage and quality without increasing power consumption. It intelligently adapts beam patterns to local conditions to enable higher-gain directional signal emulation. Ai Radar shapes signals to offer the strongest possible output, transforming what may be a weak omnidirectional signal to a stronger unidirectional one, improving throughput at the same time
Powerful Online Multitasking at up to 300,000 Data Sessions
Support for a massive data pipeline of up to 300,000 data sessions means this router has around 20 times the networking capacity of other high session routers, so multiple data transfer jobs don't slow down even during heavy load
Multi-Function Twin USB Ports
With effortless connectivity to FTP, SAMBA, UPnP AV servers and DLNA standard compatible devices, sharing and networking become easier than ever. In addition, this router can continue downloading FTTP, FTP and BitTorrent files to a connected USB external storage sidk even when your PC is turned off. The twin USB ports also allow the router to connect to USB printers or file servers, so you can enjoy simultaneous wireless printing, scanning, and file sharing
The router supports a variety of encryption, such as 64/128-bit WEP, WPA-PSK, WPA2-PSK, WPA-Enterprise, WPA2-Enterprise, and WPS (Wi-Fi Protected Setup). It also supports NAT and SPI firewalls

ASUS RT-N56U reviews

RT-N56U Dual-Band Wireless N600 Gigabit Router is rated 4.5 out of 5 by 129.
Rated 3 out of 5 by from Wired Connection is WOW fast! Well I purchased the fastest router that is available and I found that out of the box the router needed to be replaced as the wireless signal made it 15 feet and died. I called Asus and they were very friendly and helped me on Saturday evening at 9PM CST. The little bit that I was able to play with the router it seems that it is going to be a GREAT fit. Asus should have a new/refurbished router to me this week. As for the Gigabit connection its the fastest connection that I ever thought.... I was able to pull information from the web at a full 8 mbps with no issues. I was also able to throw data on the network at full gigabit! 1000mbps in both directions!

Rated 5 out of 5 by from First Router, very happy This is the first router I have owned. I have modem's with the router built in, but I am finding that having the router as a separate element gives me more flexibility. I researched routers for a couple of months and always came back to this one. So I ordered it, got it in a couple of days, plugged it in, hooked up the modem and my Mac to it, made a couple of security adjustments in the easy to use admin panel . . . haven't touch it since. Its been running smoothly and fast for more than a month. If I have problems with it in the future, I will come back here and let you all know. I highly recommend this router.

Rated 4 out of 5 by from Powerful but finnicky The router has a lot of advanced configuration options (optional) and as such can be used in numerous ways - straight router, access point, media server, sharing a mobile connection (via 3G USB), etc. It is difficult to use the USB ports, however. Sharing a USB drive is incredibly slow, and in my experience had trouble with authentication in Win7 - prompting for permissions for Unix User when deleting multiple files, etc. USB printer sharing is also not easy to configure. I purchased it mainly for the dual USB option, but find that feature to be less than useful in reality.

Rated 4 out of 5 by from Awesome router -- so far!!! Router up and running for two week so far. No problems! Home network high speed Comcast cable modem internet with wireless connection to LG BD570 Blu-Ray web-enabled player with Netflix and VuDu -- all very fast and great quality. Five computers connected -- three wireless (2g and 1n) two hardwired. Wireless range and strength throughout the house -- excellent! Have two 1gb USB attached hard drives to router for network attached storage -- no problems accessing them from any of the computers. Admin web page is simple to use -- could use more performance and status info -- pretty limited currently. Only nice-to-have would have been a guest connection capability.

Rated 4 out of 5 by from great wireless router but.... Great wireless router but be very careful when setting it up... Not sure if it was just bad luck but my router was not working once it restarted after updating the firmware as part of the initial setup (just going through the installation wizard). And it was not easy to get it back into a working state as the firmware restoration tool provided by ASUS was not able to connect to the router (using the instructions provided). I managed to fix it after finding a couple of comments in forums online to use wireshark to figure out the proper ip to set up the computer to in order to connect to the router... Long story short, the router works great now and I'm very happy with it...

Rated 1 out of 5 by from Just never got it connected Bought the ASUS on the basis of CNET and other positive reviews. Connected to a wired ethernet port, but not directly to the modem. After an hour with ASUS (in their defense they provided quick response) they thought I needed special settings from my provider, Comcast. Another hour with Comcast (confirming there are no special settings) and yet another hour with Comcast Signature Service got the router working briefly when connected directly to the modem - but not when connected to a wired ethernet outlet elsewhere in the house (modem is in a corner of the basement so I would not get good coverage from there). So...packed it up and returned to B&H (B&H was great about the return).

Rated 4 out of 5 by from Great Value I purchased because my cable modem lacks WIFI and was pleasantly surprised with its capabilities. I am not tech savvy but was able to set up both wireless networks and connect an external hard drive for NAS and DLNA streaming. I am using the 4 wired ethernet connections and the 5GHz band for dedicated streaming devices (TV and ROKU), and the 2.4Ghz band for PCs, smart phones, and Ipad. I can access NAS remotely which is pretty convenient too. It does more than I can throw at it. Even with multiple devices streaming, there is no noticeable slow down web surfing nor accessing data on the NAS.

Rated 2 out of 5 by from Stability issues I bought this router based on numerous favorable reviews. Unfortunately, I had to return mine due to stability issues. Every day or two it would drop it's connection to the internet, and give me the error message you have set the wrong dynamic or static IP address for your RT-N56U. I had no problems with my older router, however. After poking around on the ASUS support forums, it appears that this is a common issue, apparently with no resolution as of yet. I tried the obvious solutions - replaced all my cabling, checked my modem signal levels, updated to the latest firmware, etc. But to no avail. Rebooting the router fixed the problem, but it would consistently happen again in a day or two. Other thoughts... gigabit ports are nice. And I noticed a definite wireless speed improvement over my previous router. 5GHz was fast, but the signal was not as strong as I had hoped. Web interface is easy enough to use, although I wish the MAC filtering was a little easier (you have to manually type in the MAC ids). Some may love the futuristic styling, others may not. I found the design not very functional. It can't be wall-mounted, and takes up more desk space than other units that stand vertically. Overall, the unit looked promising, but couldn't hold a connection for more than a day or so. Many thanks to B&H for a hassle-free, easy return process.
