    I agree, faster than WNDR3700 and e4200 *** UPDATE, March 24, 2011
    AK (Kentucky) –

    This review is from: ASUS Dual-Band Wireless-N 600 Router (RT-N56U) (Personal Computers)

    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 as well as the firmware and all of a sudden some laptops had very laggy connections. Instead of instantaneous webpage loads, it would take literally 5 seconds to load??? So, I reverted back to and all devices are running wide open again.

    +++ UPDATE 4/30/11 Still running perfectly since new with no reboots. Simply awesome.

    Probably one of the best Wi-Fi consumer routers ever made, April 4, 2011
    Grey “Grey” (Atlanta, GA) –

    This review is from: ASUS Dual-Band Wireless-N 600 Router (RT-N56U) (Personal Computers)

    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 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. In both tests, I used the same Internet router (Cisco 871) and the same Time Warner internet connection. I never knew that my Time Warner internet connection supported 20 Mbps until I tried using Asus RT-N56U. Now I know that my Cisco 1131 – and not my Internet connection – was the bottleneck to the Internet.

    Asus RT-N56U can also be used as a NAS by utilizing one or two of its USB ports to connect an external USB drive. I tried USB flash sticks on both ports, and was able to transfer files to and from those USB drives. Additionally, you can create local users on the Asus RT-N56U and provide different levels of access (r/w, r, none) to different shares for different users. This is normally called user-based access, but Asus calls this “user with account” access. Otherwise, you can enable access to the entire drive for everyone if you do not want to deal with user-based access permissions; Asus calls this “user without account” access. I am sure most home users will choose the latter access method to avoid complexities that come with having to provision local users on the Asus RT-N56U router. I confirmed both methods of access to work when a share is mounted in Mac OS X as well as in Apple iOS (iPad2). I have run into a problem accessing a 32GB flash drive that had about 16GB of space taken by various files and directories via the the “user with account” access method from both Mac OS X and iOS, but had no such problem accessing a 1GB flash drive with almost all space taken by various files and directories; neither did I have any problem using the “user with account” access method when I tried a blank 16GB drive after moving a few files to it and then creating a few directories(see below on creating directories in the root of a USB drive). I believe that if I were to reformat the 32GB flash drive and then move all of the current files it has on it back to it, the “user with account” access method would start working properly on it. As for the file system on the USB drive, so far I have only tried FAT32, which works fine, but imposes a limitation on the size of each file to be a maximum of 4GB. If you need to go above this limitation, you will have to go with NTFS, HFS (for Mac), or ext3. I know for a fact that the Asus RT-N56U is compatible with ext3, but I am not sure if it can work with NTFS or HFS. If you have found one of these three file systems to be compatible with the Asus RT-N56U, please add a comment to this review. However, even if they are, the only file system that is compatible with Windows, Mac, and Linux is FAT32. So, if you are planning on running the Asus RT-N56U in a mixed environment and are planning to be able to read from and write to your USB drive directly from your computers as well as across the network, your common-denominator file system for the USB drive should be FAT32. If you are only planning on working with your files over the network, any file system that the Asus RT-N56U is compatible with would work for you as long as you can format your USB drive in that file system. As of this writing, the Asus RT-N56U cannot format a USB drive attached to it, so you would have to perform the…

    Better than Cisco E4200 and Netgear WNDR3700, February 25, 2011
    This review is from: ASUS Dual-Band Wireless-N 600 Router (RT-N56U) (Personal Computers)

    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. Overall this is in my opinion the best performing router that I have ever owned. Currently the WNDR3700 is considered the best but it has been out for a while now. The Cisco E4200 claims to be the best however I disagree with this due to real hands-on experience with it. There is a good amount of owner complaints already being posted about the E4200 which is similar to issues that I also encountered. The only bad thing I found with this unit is that it does not allow wall mount option. For the price, performance and features, this is an excellent value and steal.
