5 out of 5 eggsGreat Router; fast, reliable, with a lot of options.

Pros: - Works very well both on the 2.4 band and the 5 band. Prior to getting the router, the chief criticism that I encountered when doing my research was how unreliable and inconsistent its performance on the 2.4 Ghz band was. After a few hiccups early on, an update to the firmware completely resolved this issue. It should be noted that there was no need to use a third party firmware (as many people online had recommended). I just used the router's own firmware updating process.
- Has very good signal range and connectivity. Our house is relatively old and as such internet and phone line setup is a mess. Because of that, the router had to be placed in a very inconvenient and inefficient position. However, it was pleasantly surprising how well the wireless network functioned in spite of that fact. I use a desktop computer in a room roughly 20 meters away from the router, with the signal passing through 2 walls, and I get speeds that are identical on the wireless band as to when I plug directly into the router with a hard line.
- Great price. At the time I purchased the 56u, it was a bit of a gamble as there were much more reliably rated options for a bit more money. However, the higher priced units would have been more than we needed for our home network. This unit has been perfect for all of our needs at home, which includes 3 desktop computers, 3 smartphones, 2 kindels, an Ipad, and the occasional laptop. Rarely are all the devices being used at the same time, but it has been able to handle a majority of them being used simultaneously with no problems. I believe that is an exceptional value of performance for how much the unit costs.
- A good selection of features and a great UI. Working with this router is a breeze, and the amount of options and features it includes is more than enough for a home unit.

Cons: The only con I can think of is that there was a need to upgrade the router's firmware before it functioned reliably (dropped connections mostly, but sometimes not recognizing devices). The router has been so stable since updating, however, that I have a hard time even considering that a true con.

Other Thoughts: This is really a fantastic router. I cannot recommend it highly enough to people that are looking for a fast, reliable router to use for a mid-sized home. I'll add one more anecdote, that because of the ease of working within the router's UI and the traffic monitoring features it has, I was able to prove to our provider (CenturyLink) that there were issues with the lines in our area and convinced them to fix it when they had previously been reluctant to do so. Since then we've been getting speeds sometimes greater than advertised, and no dropped connections.

I waited to post a review for this router until after owning it for quite some time (about a year now) due to the reliability issues that many other people reported. It has been out of sight and out of mind since after the firmware update (about 3 months into ownership), and that is probably the best rating I could give to a router.

5 out of 5 eggsWorks as advertised

Pros: I have eight devices connected to this router, some wired and wireless. UI is Simple and compact with features. Antennas are internal, but of no consequence to the connection. The design is simple yet different from the old school box form. Wireless range is great, I say 30% better than the wireless N standard. The external status lights are a dark blue(thank you).

Cons: It needs resetting every once in a while(every week or less), with eight devices and a wireless extender connected(RP-N53) it's expected.

Other Thoughts: I use this in connection with the Asus RP-N53 wireless extender, works great, signal strength is great. Both used for a home network(no Nas or media network streaming). I would recommend this to someone.

4 out of 5 eggsWorks great, even better with merlin wrt

Pros: pretty reliable, easy to update firmware, custom firmware support
print server, vpn, lots of cool extras in this router.

Cons: it overheats. after about a year of owning it, i kept getting dropped connections. I was able to fix it by removing the case to let it air out. that seems to have fixed things.

Other Thoughts: the price is right and the router works fine. I would add in a fan or something to keep the router from overheating and dropping the wireless connection.

5 out of 5 eggsAs Expected

Pros: Fast, reliable, easy to flash Tomato by Shibby on it.

Cons: Gets hot

Other Thoughts: I wanted to write a bad review initially because after a few weeks the connection started to drop. Only after a few days of investigation I noticed the the router was getting hot (over 80 degrees C). I changed the location of the router for better airflow and added a small fan and haven't had any issues since.

1 out of 5 eggsDon't buy this

Pros: Dual band. Great range. UI is easy to use.

Cons: After 4 months of use the router now drops connection. It is incredibly annoying when I am playing a game and I get disconnected in the middle of it. It is completely random too. It was a great router before this. Unfortunately 4 months of life is not acceptable.

Contacted ASUS and they will not do an advanced RMA. I work from home and so does my girlfriend. We cannot afford for both of us to be without internet for however long ASUS decides to keep the router.

I completely regret buying this and do not recommend it to anyone.

Manufacturer Response:

Dear Jason,

My sincerest apologies to hear that our ASUS products did not meet your expectations. We will be glad to help you out with any issues you may encounter on our products. I do understand that you're having an issue with the unstable connection. To isolate this case, I would like to verify if you are experiencing the wireless disconnection, in which band are you connected?

If you are experiencing an intermittent connection, please try to place the router to a different location. That's why you encountered the disconnection from the internet due to interference. You should also pay attention to the kinds of materials the router and adapter is near. For example, placing the router on a metal desk or up against a metal wall will cause problems. Signals can travel through a wood desk easily, but metal will obstruct the signals. This is the examples appliances can cause wireless interference, including cordless phones, baby monitors, and microwave ovens.

Please use the following troubleshooting steps:
Step 1 - Please try to update the firmware version manually, you can download the latest version on our website at and hard reset the router and make sure to provide different names for 2.4GHz and 5GHz band to avoid wireless conflict and for you to notice which frequency are you connected and you can monitor the speed.
Step 2 - Please try changing the Channel bandwidth to boost the frequency of each band of 2.4 GHz to 20 MHz and control channel of 1, 6 or 11. For the Channel bandwidth to boost the frequency of 5GHz to 80 MHz or 60MHz and change the control channel to 165 or 161.

For further technical assistance or if you want to discuss this matter with me, please email me at and place case # N150995721 in the subject line for a reference.

Thank you for choosing ASUS.

Best regards,
ASUS Customer Loyalty

5 out of 5 eggsCouldn't be happier

Pros: Setup was extremely quick, though that has become standard in most things this felt quicker as everything loaded quicker and it didn't force you to hold it's hand while you set it up. I'm currently using it as an AP over my Comcast provided gateway and it significantly increased the range and speeds throughout my house. Almost doubled speeds for wifi connected devices two floors down. My area is crowded with wifi signals, specifically 2.4 (we're the only 5 network in the area) and this got around a large issue of deteriorated signal strength causing lots of issues throughout the house. So far is has performed to and above my expectations.

Cons: Resetting the router to start it as an AP was somewhat of a problem. Could have just been me though but in the end it all worked anyway.

Other Thoughts: I've always been happy with ASUS products and this has been no exception. Well worth the money spent

5 out of 5 eggsHighly Recommended.

Pros: Super fast WiFi, USB 3.0 built into router, very user friendly interface

Cons: 5G range is a bit lacking, but it gets the job done. You have to keep in mind, when this router was first designed, 5G was a brand new thing, so just be glad it has it.

Other Thoughts: In the past two years, I've gone through 3 Cisco routers, a Netgear router, and a Buffalo router. I finally got this Asus router, and have had no problems ever since.

Now, if only I could get an ISP that wasn't absolute garbage....

2 out of 5 eggsGood features but not so great range on the 2.4Ghz frequency

Pros: Great features and great UI
* I find the USB 3 hard drive connectivity extremely helpful to share files that can be accessed from any computer.
* Good long powersupply cable and a thin adapter so it doesn't block two slots on the power extension
* Great speeds when accessing items on the switch or the USB 3.0 port. I can max out the 1Gbps ports
* Guest network - this is awesome so I can provide wifi to my friends without giving them access to the other computers or my shared hard drive
* Haven't had to reset this router unless I changed a major setting

Cons: I find the range and speed on the wifi access (2.4Ghz) very low - haven't seen issues with 5Ghz. I had expected much higher range and noticed the 2.4Ghz issue as one of my laptops doesnt support 5Ghz. I've tried changing the channel and some settings based on Internet forum posts where people have seen the same issue, used INSSIDer to find channels that don't have conflicts at my home but that hasn't worked either.

At first I thought this was an issue in my apartment but after moving to two different apartments and changing the location of the router within my apartment, I've sort of given up. I don't get decent range on my laptop in my bedroom which is <30 feet away from router (in the living room) and is separated by just two drywalls and this is across all channels. Unfortunately, I wish I had verified all this when I first got the router - I would have returned it. I have the router setup centrally on a single floor apartment. The other thing I notice is that if I keep a ping -t ON on the laptop in my bed room, every 30 seconds to minute or so, I get a couple of pings which result in destination host unreachable. I don't see this on my computer which is connected to the router via wired network so this is definitely a wifi issue.

I ended up buying a Netgear power line adapter kit and used that along with my old router to get range in my bedroom. I wish I didn't have to do that. Given how great ASUS router reviews have been, but given my experience with the unit I got, I'm not sure I'll recommend them.

Other Thoughts: I don't use the AIDisk (to share your usb drive so it can be accessed from anywhere) so I don't know how that works. I've also not tried the download manager and print share features.

Given my range problems, I wish I had bought a router with external antenna - maybe that would have solved some problems.

Manufacturer Response:

Dear Abhishek,

Thank your for your time in posting a review about our products. We are sorry to hear your experience with the router. Let me assist you, have you tried changing the channel bandwidth of the router? or check your 2.4 GHz frequency logs to see if there is an issue or if there are signs that the firmware wasn't loaded properly. Also it is important to have an updated firmware for the router to fix if there is any issues. If there is anything else that I can help or assist you with just email me at and place the case#N150719614 in the subject line for reference.

Thank you for choosing ASUS!

Best regards,

5 out of 5 eggsVery robust wireless router

Pros: This router has very good wireless performance on both 2.4G N devices and 5G AC/N devices. I can get up to 25MB/s transfers to my wired devices from a PC equipped with a USB Wireless AC adapter.

Never needs to be rebooted or reset, either. It just sits there and does its thing.

The power supply has a nice, long cord and the adapter itself is not one of those gargantuan bricks that block three outlets on the power strip. This is the first router I've owned that didn't require an extension cord for me to put it where I wanted it.

It has some blue status LEDs on the front (which are not obnoxiously bright) but the individual port link LEDs are in the rear.

The setup and web interface is fairly straightforward as well. I like that it allows you to set static IPs on your devices that are outside of the DHCP scope you've set... so if you set the router to give out IP addresses in the range of to for example.... you can set a static IP for a device using if you wanted to. I've had other routers that wouldn't let me do that.

and maybe the biggest pro of all for some people... It supports DD-WRT! I don't personally use it on this router (I've tried it, but the stock firmware does all I need and then some so I ended up reverting) but it's nice to know that it has 100% support for it.

Cons: Nothing here worth taking off an egg for but if I had to nit pick, here goes:

No option for external antennas. I knew this when I bought it, though.

Included LAN cable is just a typical CAT5(E?) of questionable quality like you'd find included with any router and does not have "snagless" ends.. threw it in my bric-a-brac bin and used CAT6 instead

Other Thoughts: Would definitely buy again.

5 out of 5 eggs100% worth the buy.

Pros: Wifi range is excellent. I have a 3 story brick house about 8 to 10 active devices connected to it most of the time. Video streaming, file sharing, browsing is a breeze, no hiccups. Outdoors, the signal is awesome. I can use skype even 300 feet away with no problem, this is done with beam-forming tech this router has, even though the router is located inside the house (living room).

So keeping everything connected around the house is a breeze. Even if you have 1 wifi bar on your phone or laptop it will still pull minimum of 10Mb of internet, which is plenty.

Cons: None so far.

Other Thoughts: After researching the marked for a solid wifi router on the budget side this is the best I could find. Looking also at the internals and other technical reviews of this product I found that I cannot go wrong with it. I was sceptical about the software and how good it works, but ASUS improved every bug or added new features to it constantly until everthing worked perfekt.

Best value for money overall.
