Very Nice AC Router..

This asus is very nice, speed on the 5GHz band is reasonable as long as there are no walls in the way.  2.4GHz has nice range as well.

I bought it because my old router died on me and so far the AC1000 is doing me well! Specs are nice for its price and very compact for easy cover.

Happy to say that I am satisfied with the range of the Nighthawk AC1900. I now have WiFi throughout my whole house and even outside in my back yard. Satisfied with the speed as well. A+ Product.

Very nice product, and a great price.  It's the old model, but has great security features (wpa/wpa2) as well as a host of firewall and security rules that you can configure.  Somewhat wonky initial setup, but nothing that you can't get through.  The speeds have been very good on both my existing "g" cards, and the trendnet "N" card that I purchased w/ the router.  A good unit for the price!

All the features you'll expect from a router in this price range, combined with great range. Just waiting for the ac standard to be ratified....

This DLink router has been used for over 1 month now as an Access Point within our home network. It replaced an Asus RT- N56U Black Diamond Router which was running in AP mode to extend our range. The Asus was one of the better N routers available. The dir-810l however has worked well since we changed them out. Our wireless range has been extended on this router.

The router looks nice however there is no way to wall mount it if that is a concern for you - although the unit is designed with a vertical stand and does look quite nice.

On the negative side Dlink kept costs down by not going with Gigabit ports for the LAN ports included on this unit. This is why the device gets 3 out of 5 instead of 5 out of 5. In the role I use it for, which is as an AP range extender, this is not too big of a concern but if you make an AC router, please, give it gigabit ports. It is common sense especially with the higher throughput of the AC radios. Right now this is not too much of a concern as the only wireless devices are not running anything that would be limited by this factor, but I will be looking to replace it with something that has gigabit ports on it.

If you are looking at this as a primary router with some LAN connections running to it look at something else. If you just need it for wifi then it is a pretty good fit. Dlink you hurt yourself by not putting gigabit on the unit.

I have two of these setup as a 802.11AC wireless bridge. I get consistent connectivity and excellent speed with the units being about 50 ft apart separated by multiple walls (2x4 stud/drywall construction). Running strong for a week now w/ no reboots required.

I don't like the dumbed-down UI compared to other D-link products I've used (DIR-868L).

I have a Ubiquiti EdgeMax Lite router and a Netgear 16 port switch and I am very happy with my home wired LAN. I have the big streaming hogs like my Samsung TV, Apple TV and Denon Audio Center and Vonage VOIP on wired LAN with QOS. But I have a 11K Ft2 property with a 2K Ft2 main main house a 1K Ft2 yard and a 400 Ft2 separate garage at the far corner of the yard apart from the main house. With all the mobile devices now being used for streaming and online gaming, multiple Alexa devices streaming audio and a wifi security camera next to my garage, we had issues with wifi traffic across our property. What I needed was simply a way to handle more Wifi speed at greater distance for all these devices without disturbing my wired LAN network. I had an old b/g/n wifi access point from EnGenious and another from Apple and they were not giving more than 20 MBps. I first purchased a Google Wifi Mesh 3-point system but returned it because it did not work with my existing router and wired network. I then decided to purchase one Ubiquiti AP-AC-PRO and two Ubiquiti AP-AC-M points.

Configuration:
I plugged the AP-AC-PRO into my Netgear switch via the provided Ethernet power injector dongle that came with. (because my switch does not support PoE) This AP-PRO was located in the center of my main house. I put one of the two AP-AC-M mesh points at the far end of the main house where we had a particularly weak signal before using the AC adapter only. No wired network. (About 40 feet away from the center AP-PRO and through two wood+drywall walls). I then put the other AP-AC-M mesh unit in may garage (AC adapter only no wired network) which is a separate structure located about 60 feet away from the AP-PRO and through 4 wood+drywall walls.

Setup:
Setup was not as intuitive or simple as it should have been for the AP-AC-PRO and I deducted one star for this. Ubiquiti makes great products but they are more complicated than they need to be and are targeted more at commercial IT market. However for consumers who want fantastic performance at a reasonable price, and know a thing or two about IP networking, it is well worth the effort.

I highly recommend using the Unifi Controller software to setup the units. I had no luck getting the setup to work using the Unifi mobile app for iOS and even if you do get it to work, it is very limited what sort of configuration you can do with the mobile app by itself.

The Unifi Controller software needs to be downloaded from Ubiquiti's website and installed on your PC or Mac. (I used MacOS Sierra with no problems) and you don't need to run this software all the time; Just while you are configuring the Access points. Take note that both the username and password are case sensitive when you set them up.

Also note that while your setting the access points up your PC/MAC running the Unifi Controller software must be on the same wired LAN network as the wired AP-AC-PRO access point you are installing.

Also note that if you do wish to try using the Mobile app to setup the devices without the Unifi Controller software, you will still need to download the Unifi Controller software User Guide pdf from Ubiqiti's website and refer to Appendix C on page 133 for instructions how to use the mobile app.

Result:
I now get speeds at the far reaches of my garage, all over my yard (between my garage and main house) of at least 150 Mbps and everywhere in my house is even faster. I have tested it with 6 devices playing online Minecraft, two devices watching Netflix and Alexa playing music via Spotify and there are no issues with speed at all. I have yet to test with the security camera but that is next. Very Happy overall and I will be keeping these units.

Picked this up to go with a newly purchased AC router. Gives me a very good signal about 40-50 ft from the router (I connect at about 650mbs). Stable connection even when streaming for hours. Happy with this purchase.

Unfortunately I don't have any 802.11ac clients so I can only really review the router as I would other routers I have purchased. I'd highly suggest you find someone with some of those device's review and take advantage of any learnings they have related to that functionality.

The router was easy to setup, doesn't disconnect any more than any other router I use in my apartment building (18 floors of tenants so there's a lot of interference), and it accomplishes its mission of delivering the Internet to my wireless devices.

It's an overall great router and I don't think you'll be disappointed getting it. That said, I think it's not worth buying unless you already own a 802.11ac capable device. Most people will not really find use of the feature at this point in time (lack of devices which support it) so you should really just save the money unless you plan on doing it in the foreseeable future.

Bought this a couple of months ago because of dead zones in a multilevel house. My former router was a modem-router combo that had problems after the first 3 months (another brand). The AC1900 was easy to set up and the automatic security was a plus. For the first time ever, I have wi fi outside my home and everywhere inside. Wife is pleased that she's no longer getting dropped off. I'm pleased that I no longer have to climb stairs just to power on and off the old modem.  This (It's listed here (10-30-15) for $50.00 less than I paid) IS a bargain. Highly satisfied with my AC1900.

I bought this router an year ago and so far it has been working flawlessly. I had a hard time deciding on a router, when my previous router from another brand began to go bad with dropped signals, since most of the router reviews were very mixed. I have a two-story home and I can get decent speed and range in most of the spots I have tried with this router. I am an advanced user and hence never had to contact customer support for setup and installation, and so I cannot comment on that aspect.

I received the Linksys AC 1900 in a very prompt time and was very delighted with the ease of installation and with the help it provided in increasing my network. It was very simple to install and getting it connected with my current network was very easy. Just follow the instruction sheet that came with it and you'll be up and running in no time. I've only had it now for a couple of weeks and it is still working flawlessly. If you have the need for a little improvement in the strength of your network, this Linksts AC 1900 should do the job.

I purchased this for my daughter  interested in the AC support at moderate price.  However I like it performance and went ahead and purchased another for my self  ...

It is not the fastest AC router but for the money ... I would say it is not a bad choice.

Highly recommend. New 802.11 AC chipset allows for greater distance for coverage. Easy to set up.  Keep in mind you would need to have the internet speeds to achieve the AC data rate.

Given the fact that five people have not only read this review, but felt as if it was "not helpful," I feel I should say this: I reviewed this router because I received the item to review. I want to state, very clearly, I can set up a router, I can even maybe go a few steps further than many people, but I'm NOT an expert on the more technically complex details covered by other reviewers. Perhaps I was the wrong person selected to review this item, but I promised a review, and I gave an honest one. I'm still very, very pleased with this router, and still give it five stars. It works perfectly, it looks beautiful, and it was easy for me to set up. If you need more information than that, please refer to one of the many excellent and very detailed reviews.&nbsp;

I need to begin this review by admitting that I am not a technically savvy person. Routers and computers work or don't work for me, and while I can usually figure out basic problems, the more complicated and technical issues covered by other reviewers of this product are well out of my knowledge base. My old router, also a TP-LINK, seemed to be giving out, so I was happy to get to try this. I had no problems whatsoever getting it set up and running, and signal strength is strong -- although considering that I live in a 700 sq. ft. apartment, I would be surprised if it weren't.

If you're interested in the more sophisticated features offered by this router, or have questions about the security options and newest ac wireless standard... well, I apologize, I'm not your guy. There are some excellent reviews here that go into details I can't touch.

If you're like me, though, and looking for a simple setup and an up-to-date router, I certainly am happy with this one.

I've had this router for almost 2 years. I purchased it refurbished from Amazon.  I will be upgrading soon because I want to get something that is wifi AC enabled.  I have used it with an xbox one playing Halo Multiplayer, watching HD netflix on my iPad and browsing on multiple smartphone all at the same time.  No significant issues. From time to time, I reset my modem and router, but more often than not it is the modem causing issues not the router. I couldn't be happier with the value provided by this router for the last two years. The ability to give priority to certain devices is a great bonus feature. It was also really easy to install.
