Experience: 5 Months

Fast, stable and good range
Bought this to replace a Netgear WNR3500L in a small space (300sq ft).

My wife noticed the difference in speed and connection strength. Purchase justified.

Experience: 7 Days
 Verified Owner
Extremely efficient, super fast wireless. Awesome interface for the settings. Also looking really good.
I bought this because the wireless on my Bell router was atrocious. I wanted something reliable and worthwhile. Setuping this router could not be easier, everything was up and running in 30 minutes (this includes installing the latest firmware for this router which downloaded itself as soon as it was connected to the internets). I topped the wireless speed possible on each device I had, so I can definetly say this is super fast (we have 1gpbs speed and just on my phone it went higher than 300 mbps). So if you want something top of the line, futureproof and easy to use and you got the money, you can click on buy.

Good range
OpenVPN Built in
Looks pretty cool
Decent amount of settings for a consumer router
a little on the pricier side for something like this
It's been good so far. No dropped connections, no speed issues. Lots of useful built in features like OpenVPN and useful quick tools like netstat and wake on lan built right in. Works as you'd hope it to.

Experience: 2 Weeks
 Verified Owner
Great range and speed! User interface is well laid out and there are so many features.
More than I usually spend on a router but can't go back now to cheaper routers.
Great router. Surprised at the range available would definitely buy this again. It was more than I was hoping to spend but I don't think I can go back to buying cheap routers again. I will have to get another one for my dad too!

Good signal strength
Lots of internal memory
Fast processor
Long Range
Easily flashable firmware
none so far
I wanted to replace the router that my ISP (Shaw) provided as I found its functionality limited. I flashed it with ASUS Merlin latest firmware straight out of the box fairly easily. Only problem I had was my first connection to my ISP router after setting it to bridge mode, caused it crash and had to do a full reset. Since then it has worked flawlessly. Provides a faster wireless connection for all of my wireless devices, and the wired connection seems a little faster as well. I don't currently have any AC devices, but my next laptop and phone should. Hopefully that will provide some future proofing.
ASUS Merlin firmware gui is pretty easy to navigate, responsive, and easy to use. Highly recommend flashing router as soon as you get it to take advantage of all of its features

Experience: 2 Days
 Verified Owner
Easy setup, fast, reliable.
No USB3.
Great router, was easy to setup and keeps a reliable connection, so far. It's nice that it can run DD-WRT although I haven't needed it as the Asus firmware performs to expectations.

Featurewise I enjoy the QoS settings.

Experience: 1 Months

- powerful
- wireless AC
- gigabit lan
- 3rd party firmware
- gets kinda hot
Great router. Has a lot of great and excellent features. Recommend using Merlin firmware.

Experience: 15 Days
Great price, great system behind. Possibility to boost antena pretty easily. Compatibility with DD-Wrt
Seems to heat a bit more then my old router but not realy an issue.
I would recommand this router at this price for sure. Easy config, AC, a lot of possibility.

Experience: 3 Months

Easy to set up, strong signal, and fairly compact.
The network printer sharing is glitchy and doesn't work with my printer. Be sure to check your printer's compatibility, even though mine is compatible it would not print. The printer would be in endless cycle of receiving data.

The firmware /IS/ dated, and there is a minor security flaw with it so it would be advisable for owners to upgrade to the latest firmware immediately.
I purchased this router back when it was on a $50 discount in October 2014. So far I enjoy using it, it does a fantastic job in with the 2.4 Ghz penetration. For those of you expecting 5 GHz across your entire house, you'll probably be disappointed. I have it in my basement, and it can reach my first floor at best, 2nd floor is not there. 5 GHz doesn't have strong penetration capabilities by the nature of its frequency.

The biggest disappointment is the network printer sharing. It relies on a program that you have to download to do its job, and unfortunately it doesn't do it successfully for my printer. The printer does get detected, but it never succeeds in sending data to the printer, it'd keep my printer endlessly in receiving data mode. I let it stay like that for an entire day just to be sure. It would be nice to be able to have all the computers enjoy printing without turning on a single computer, but it is as it is.

As a router, I have no complaints with its reception. Only time will tell how long this router will last though.

Experience: 2 Days
So far so good! I can definitely tell the processor inside is faster than in my old router.. everything is that much more responsive now (including general usage within my LAN). Great coverage. My old router couldn't reliably reach my master bedroom on the 5ghz band. This one does it with no problems despite being at the opposite end of the house.

Loaded with features.

Firmware upgrade brings AICloud 2! I was considering a more expensive router in order to get this.
Firmware - it shipped with a fairly dated firmware.. I update d to the latest and lost 5ghz wifi. I "downgraded" to a firmware update  from Sept 2014 and it worked fine. Back to the Oct 2014 firmware and lost 5ghz wifi again. I went back to the Sept 2014 firmware and 5ghz works.. I have submitted these results to Asus.
Overall a huge upgrade for me. I'm really happy with the purchase.

I was pleased to see that a firmware update  got me AI Cloud 2. I'm already making extensive use of it.

There are very few (if any) actual devices that actually work at the higher speeds of the AC1900 and especially the AC2400. Most consumer laptops, tablets, phones come with 1-2 antennas.. Those high end routers require 3 antennas to make full use of them!
