Dual Band Gigabit Wi-Fi Router

  • Engineered to enhance dual-band communication
  • Adjustable for optimal positioning in single or multi-story buildings
  • Removable to accommodate antenna upgrades
  • Double the bandwidth to maximize throughput
  • Open Source Support



Performance Perfected
Engineered to deliver best-in-class networking performance, the Linksys WRT1900AC Dual Band Gigabit Wi-Fi Router delivers an unmatched user experience and ultimate Wi-Fi coverage for your home. We've upgraded the iconic Linksys blue-and-black design and outfitted the router with the latest Wireless-AC platform along with the industry's first four antenna configuration with a powerful 1.2GHz dual-core ARM to provide exceptional signal strength and range to simultaneously support multiple users. We also added a unique dual eSATA/USB 2.0 and a USB 3.0 port to the Linksys WRT1900AC to conveniently connect an array of devices and experience lightning-fast transfer speeds.

The WRT1900AC features exclusive SMART Wi-Fi software to monitor and control your network anywhere and anytime. It's our first router to offer the Network Map smart tool, providing an intuitive at-a-glance view of your entire network. For advanced users who want to customize their firmware, the WRT1900AC stays true to its lineage by offering an OpenWRT compatible firmware to allow advanced users to expand the capabilities of the router.


Four High-Performance Antennas for Maximum Coverage and Reliability
To provide strong, reliable Wi-Fi coverage throughout your home, the WRT1900AC is the first router in the market to feature four external adjustable antennas that ensures your Wi-Fi signal is always at maximum strength, keeping everyone simultaneously gaming, downloading and streaming without lag. The antennas also enhance 2.5GHz and 5GHz simultaneous dual wireless bands performance for a strong, reliable Wi-Fi signal that eliminates dead zones even in multistory homes. The antennas can be detached for future upgrades.

Leveraging the Wireless-AC standard, the WRT1900AC delivers innovative Beamforming technology enabling the router to strengthen the wireless signal to specific devices, rather than simply sending out Wi-Fi in a general direction. Now you can experience faster network speeds, better wireless range, reduced interference from other devices, and stronger Wi-Fi connections.

Fastest Dual-Core ARM Processor to Surf, Stream, and Game Simultaneously
With a professional-grade, 1.2GHz dual-core ARM CPU the WRT1900AC is one of the most powerful Wireless-AC routers in its class capable of moving data at unprecedented rates in even the busiest of networks. Pushing wired and wireless speeds to their ultimate capabilities, the Linksys WRT1900AC router can easily support multiple users at once - whether they're streaming music, watching HD videos, or playing online games.


Most Advanced Wired Connections
For blazing-fast performance, we equipped the WRT1900AC with four Gigabit Ethernet ports - which are 10 times faster than Fast Ethernet - to provide the fastest wired speeds. Using the USB 3.0 port, you can add external storage or other devices to share content across your network. For those with an external SATA storage device, the WRT1900AC is outfitted with a unique eSATA port for added convenience and optimal data transfer rates; it can also serve as a USB 2.0 port.


Monitor and Control Your Network - Anytime, Anywhere
With the industry-leading SMART Wi-Fi software you can monitor and control a home network from anywhere, anytime using a PC or mobile device. You can set parental controls to restrict Internet access during certain times of the day and create secure Wi-Fi passwords for your guests. You can also monitor activity on your home network, add new devices, and check upload and download speeds. In addition, Linksys SMART Wi-Fi allows you to prioritize which devices on your network receive the most bandwidth to reduce lag times and buffering when you're streaming HD media or gaming. Your Linksys Smart Wi-Fi account also gives you access to apps that provide additional ways to control and interact with your home Wi-Fi network.

WRT1900AC is the first Linksys router to incorporate the Network Map tool in SMART Wi-Fi when using your SMART Wi-Fi account. Network Map provides a visual overview of your network allowing you to see all devices on your network, their online status and signal strength, and also measure how much bandwidth they're using at any time. It also allows you to create personalized identifiable names so that you can identify your connected devices.

Open Source Ready
While the Linksys WRT1900AC provides an outstanding experience via SMART Wi-Fi immediately out of the box, advanced users can further modify the router, which will have Open Source firmware available. Developed for use with OpenWRT, an open source, Linux-based operating system, the router offers an additional layer of customization to suit an individual's needs.

Wireless Repeater Mode and Wireless Bridge Mode for a More Powerful Wi-Fi Network Signal
Users who own a second WRT1900AC will enjoy a more powerful wireless signal using the SMART Wi-Fi interface. Now you can extend the Wi-Fi signal for both of the router's dual bands (2.4GHz and 5GHz) with Wireless Repeater Mode, or just one of the bands with Wireless Bridge Mode. Either option effectively turns the WRT1900AC into a powerful range extender or wireless bridge, adding range and speed to wired and wireless connections on your network.

Advanced Security to Stay Safely Connected
To keep unauthorized users from accessing your data, the WRT1900AC offers Wi-Fi Protected Setup along with WPA2 encryption and an SPI firewall for maximum network security. Parental controls enable you to restrict Internet access for children.


Minimum System Requirements
For router setup and Linksys Smart Wi-Fi access, the WRT1900AC requires Internet Explorer 8, Safari 5, Firefox 8, or Google Chrome. For printer sharing and user documentation, it requires a Wi-Fi-enabled PC that has a CD or DVD drive and that runs Windows XP SP3, Windows Vista SP1 or later, Windows 7, or Windows 8; or a Wi-Fi-enabled Mac that has a CD or DVD drive and that runs Mac OS X Leopard 10.5.8 or later, Snow Leopard 10.6.1 or later, Lion 10.7 or later, or Mountain Lion 10.8 or later.

5 out of 5 eggsVery happy with this router! Recommended for techies and for everyone else with 2 caveats

Pros: Speed (1.2Ghz dual core)
Wifi performance
Open Source ready
Lots of RAM (256MB)

Cons: Stock firmware is not very good

Other Thoughts: Like everyone else I've been waiting for a replacement for the classic WRT-54G for quite a while and am happy to report that my WRT1900AC is shaping up to fill that role. While I agree the stock firmware leaves a lot to be desired, I was still able to get what I wanted accomplished. I've got it set the way I want now and am very pleased with the performance and wifi range. I've got my USB3 HD serving my media on it and while the QOS on the stock firmware doesn't have much for advanced features it's serving my needs perfectly. I have an Asus RT68U at my office and while I'm also happy with that router I prefer my new WRT1900AC and think that as time goes on it will prove to be a much more versatile, capable and future-proof router that the RT68U or the R7000. I won't hesitate to recommend the WRT1900AC to enthusiasts. With the 2 caveats that the price is a little high and the stock firmware is not great, I would also highly recommend it to non-techies. If you don't like the firmware then flash it with something else; that's the whole point of this router!

2 out of 5 eggsProblem Router

Pros: Speed

Cons: The router has disconnect problems, and reboots daily. This is a known problem with a lot of people. The latest firmware doesn't fix the problem.

Other Thoughts: I use to be a Linksys fan, but since Belkin took them over, the routers are not reliable. I went with a different brand router, and have not any disconnect or reboots.

3 out of 5 eggsMediocre

Pros: Solid build quality
Seems reliable
Dumb as dirt easy to setup
I would give 7 eggs for build quality and presentation

Cons: Dumb as dirt setup
Given the high $$$ of this unit I think it would offer more setup options. There should be a status screen showing uptime.
I have no want or desire to sign up for yet another online account. This unit is not as bad as some of the other Linksys products that demand a setup CD be used. If you look closely at the login screen there is an option in tiny text to just login the router. The firmware of this router feels like a $40 router. Open source support is buggy at best, that is if you do not "brick" the thing trying to flash it.

Other Thoughts: I would be angry if I paid $200+ for this router.
There is no way I could give any more than 3 eggs for this router. I can get similar features and TRUE open source capability for less than half of what this unit costs. They may have gotten the hardware right but awesome hardware without software is just a paperweight.

Did you find this review helpful? Yes No

5 out of 5 eggsLook no further

Pros: Works in Bridge mode (FIOS)
Setup was breeze.
Quality build and parts
Stream Media, Plex, Netflix well
No lag in Online Gaming, Steam and Xbox Live
No echoes on VOIP, Skype, Face Time
Apps for Remote Management

Cons: Heavy,

Other Thoughts: This thing looks like the Predator.Its a good thing too, its a beast when it comes to managing my 10+wifi devices and 4 hard wired connections going on simultaneously with out a hiccup.

4 out of 5 eggsVery good hardware, weak firmware

Pros: This router has clean design, 4 removable antennas, and eSATA and USB 3.0 ports.
Hardware-wise, this router is very good. Routing capabilities are probably more than most people will ever need.
Having USB 3.0 and eSATA means this router can really be used as NAS. Much faster than USB 2.0. I attached USB 3.0 external HDD and I was able to get 73MB/s write and 83MB/s read speed over gigabit LAN.

Wi-fi range is also very good. I was able to get usable signal upto 150 ft from my house. About 50 ft more than TP-Link TL-WDR4300. This really depends where router is installed and how many wi-fi signals are around. Since I live in a condo with wi-fi router in pretty much every household, poor range was expected.

Unlike many of old Linksys routers, this router has wall mount holes. For those who wants to mount router on wall or ceiling like me, this is big plus.

Cons: Web interface looks clean and nice, but lacks features. It does have all the features you would expect from regular router. But no more.

VPN server feature would been nice add-on with such a powerful and expensive router.

There are some non-critical problem with web interface.

Web interface also lacks a way to view current setting and status at ease. Unable to view WAN IP address unless goto trouble shooting and pull report.
No way to view uptime.

It is not possible to change DNS setting for internet connection (WAN interface) while still using DHCP for acquiring IP address.
There is work around. Set DNS you want in DHCP server for local network. Strange thing is normally this should assign set DNS servers to client computers. Instead, DHCP server always sets router as DNS server, than use DNS server settings on router to query.

Another strnage behavior I found is that it is not possible to set DHCP reservation outside configured IP address range for DHCP server. In all previous routers I have used it was possible to set DHCP reservation to IP address that is not within DHCP server IP address range. (I reserve ip addresses below 50 for static IP address devices except for my desktop which I assign using DHCP reservation and still haver IP address below 50 )
There is work around for this though. Change DHCP server IP address range to include IP address you want to reserve. Then set DHCP reservation. Now, change DHCP server IP address range to what you want. Now DHCP reservation will work even if that IP address is not included in DHCP IP range.

It would be nice if it is possible to set my own time server. Instead timer server is hard coded in this router and only time zone can be changed.

All of the features I see in this router's firmware is same or less than what I saw in much cheaper routers under $100.
I would expect more from router over $200.

Although this router is advertised as open source ready, support for open source is bare minimum. Open source firmware is rather buggy at this time and limited functionality. It is usable, but there may not be much of advantage to go for it if all you want it to do is just basic routing. I read this was due to lack of support from Linksys/Belkin to openWRT developers.

Router runs fairly hot. Surface temperature of the router was at 120F (with room temperature at 80F). There is built in fan inside router, but it never kicked on. I wonder at what temperature this fan is supposed to kick on.

Other Thoughts: There were some reviews saying firmware is unstable. I updated firmware to current version ( the day I set it up. Did not see any stability issue for a week. Will have to run for months before really commenting on that.

4 out of 5 eggsLinksys WRT1900AC Router

Pros: WIFI coverage is outstanding. Had issues in the basement receiving a signal from my old router and with this one it doesn't miss a beat. I had "dead" zones that most devices would just lag. This is the closest I've been to my Linksys WRT54G, that was my original, most trustworthy router. That thing was perfect, except that it just got a little old in technology. It never failed, though. The 1900AC seems to be there, although I haven't had it for more than a few days, so time will tell. No dropped signals or reboots required yet, which is a good sign. WIFI is definitely boosted. All throughout the house it is stronger. The extra ports (USB and eSATA) are great to have too, although I haven't used them yet.

Cons: It is large, if that can be a con. You need to have space for it to sit flat for the antennas to project as they should. I've seen where others have said that it quit working or had problems after a few weeks or months of use. I will update my review if that becomes the case for me. So far, no issues in drops or complete failure to work. I will note that I am using cable, and not satellite or DSL signal, so I can't offer any insight on how it works with them. Maybe other who are having issues is a firmware problem? Not sure...

Other Thoughts: I think routers are hit and miss on how they perform in each household. I don't know how to confirm that, but I've had the same router that performed perfectly in one place and then horribly in another place. Not sure how that happens.

1 out of 5 eggsTotal Failure at 1 year

Pros: Good while it lasted!

Cons: I am very disappointed with Linksys and their support group!

I purchased this WIFI router from the Linksys store on April 11, 2014 for $250 and received it on the 17th. On April 13, 2015 the router failed to connect to the internet and my wired and WIFI devices did not have internet access. I was having periodic failures for about 1 month and a reboot would solve the problem. I knew my router or modem was about to fail, but I did not know which one. On April 13th, I tried several reboots of everything and could not get an internet connection on my WIFI or wired devices (internet light was blinking white). When I disconnected the router and connected my desktop PC directly to the cable modem using a LAN cable, I had a reliable strong connection. There were no problems with my cable modem. The Linksys router worked flawlessly until this time.

On April 14, 2015, I called Linksys technical support. The call was immediately answered by Bryan from their tier 1 support group. Bryan remotely connected to my desktop PC, but he could not establish a connection to the router. He looked at the event log and msconfig on my desktop PC and said the problem with my router was because my desktop PC had major problems. I asked him several question. He was rude, hateful, and condescending. He told me I knew nothing about computers or networking and that I must follow his directions. He said he would transfer me to a tier 2 support person and he would fix my desktop and the router would then start working. I asked him how the desktop is preventing my ipad and iphone from connecting to the internet. He raised his voice and said there were no problems with the router and I needed to pay $49.99 for the tier 2 person to repair my PC. I asked him to tell me how to correct the router problems and he refused. I asked him about my warranty and he said there was nothing wrong with the router and all problems were caused by my desktop PC! He would not honor the warranty! I am shocked at how he treated me and how he would not tell me how to correct the problem.

Byran was crazy to think that I know nothing about computers. I build computers as a hobby and I run a lab with 10 custom computers, which control millions of dollars in analytical instruments. I did not argue because I knew it was useless.

I realized from looking at Linksys’ support page the product is only supported for 90 days, which means the 1 year warranty is useless. They are not going to provide troubleshooting for their products past the support date without a fee. If you have problems past the 90 days you will need to solve it yourself or purchase a new router.

Other Thoughts: When you purchase this router you are NOT getting the same technical support and product reliability as seen with the original Linksys WRT54. The company was purchased by Cisco, cannibalized, and then purchased by Belkin. The original technical leaders are probably long gone. The WRT1900AC is not going to match the reliability and ease of use found in the WRT54. That being said, the WRT1900AC is great idea and leading technology. Too bad Linksys does not have a good support system and warranty coverage for hardware and software problems.

5 out of 5 eggsWorks Great!! Easy to install!

Pros: -Provides max speed of internet service provider
-4 detachable external antennas provide very good range in 2-story house
-USB 3.0 is plug and play and showed up in network directory
-No issues freezing or lagging
-Online Gaming works great and provided low pings
-Torrenting works great, router doesn't hang when someone is torrenting
-Easy to setup; no CD installation needed
-4 Gigabit ethernet LAN connections
-Solid Build and wifi signals
-Activity light can be disabled
-Parental settings such as blocking internet website and internet access hours
-Flat ethernet cable included

Cons: -Large size

Other Thoughts: I use the internet for basic things like torrenting, downloading, hulu, netflix, PC gaming, PS4 gaming and video chat. I’ve also used the WRT54G when it became popular a while back using DDWRT so I am familiar with using open source firmware. I just recently switched my hardware to AC and have B/G/N devices so I do have the latest in new and old tech like iPhones, Android phones, Mac Minis, PC, iPads, chrome cast, etc.
My installation directions:
1. Connect ethernet from computer to router. Connect ethernet from modem to router.
2. "" Brings you to the setup browser. NO need to install the cd. No need to make an account in linkysys (just how it's always been)
3.Restart Modem when prompted.
4. Router was updated to the latest firmware automatically.
5. Manually adjust the wifi ssid/password (default wifi password is with the install CD packet)
6. Some things I adjusted were to create a single SSID that combined 2.4ghz and 5ghz for simplicity
7. You can also change the router admin password
8. I manually adjusted the wifi channels based on Apple's SCAN using Wireless Diagnostic for the channel with the least amount of network congestion
9. Disabled guest access and media prioritization

On Comcast 100Mbps download. Hard wired Ethernet I get 95Mbps download 10ms ping using
-on AC devices I get full 95Mbps download speeds upstairs and downstairs
-on 5ghz N devices I get full 95Mpbs internet speeds upstairs and downstairs

I connected a USB 3.0 drive filled with movies and was able to access the movies from all the computers without any issues.

What was really impressive was that during torrenting the router didn't hang or slow down for other users who are using the internet. I had this issue with my past routers including the Apple Airport Express and Airport Extreme. The RSSI signal went from -70 to -53 switching from Airport Extreme to WRT1900AC in the upstairs room so the signal is a lot stronger.

For my needs this router functions flawlessly. I was put off by the reviews because they are not good and the price is so high >$200. But I am very impressed considering it is on the stock Linksys firmware and has provided rock solid internet connectivity.

4 out of 5 eggsSolid, costly router

Pros: Heavy/solid construction
Nice looks of the old WRT54G
Front panel lights are subdued

Cons: WPS button is tiny and on the back of the unit
Despite manufacturer claims to be good with Open Source, support for it is still shaky

Other Thoughts: This router is a bit of a throwback to the days of the Linksys WRT54G. Only by looks though really, and from other newish Linksys devices (such as the SE4008 gigabit switch designed to stack with this unit). Because of this throwback look, one might think that a plethora of open source firmware is available to slap on this thing, but that’s not the case. While OpenWRT does support this device, you can find that there’s been lots of issues over the past year of its existence, and only recently has newer software come out to stabilize this firmware. DD-WRT is not supported at all. Despite these let downs, this router’s stock firmware is very nice with a lot of great features. The menus and setup are very clean and polished, not to mention the ability to use a mobile app to control your router’s settings (such as allowing guest access). By the way, check your firmware as my unit shipped with an older firmware version, with a pretty significant upgrade in going to the newer one, so check yours.

In the box you’ll find the router, four antennas, power brick (which is a welcome respite from the world of wall warts), a 4 foot flat network cable, and full sized CD with quick instructions. Taking it out of the box you’ll note how hefty it is. The feet are nice and wide with huge rubber pads on them (which Linksys thoughtfully allowed a screwdriver into the screws without tearing off the pads). I personally hate when a router is so light the cable tension begins to pull it off the table. Not so with this beast. There’s a good amount of ventilation on the top of the unit, and the antennas are nicely spaced. It might be nice if the antennas were labeled, so if the user wanted to use aftermarket antennas just on one specific frequency they could. No big deal though.

Linksys wised up and put USB 3.0 on this unit as well as eSATA for shared network storage, and I always like seeing an actual power switch, so I don’t have to pull the plug just to reset it (the reset hole is very small on this thing). Also note the WPS button is very small and in the back, which is pretty lame if you use it often. I like the thought that went into the indicator lights on the front panel. This is the first router I’ve seen where I didn’t have to completely shut off or tape over the LEDs! The subdued thin lines give off a TRON-esque appearance.

The performance of this thing is exactly as expected, with all the bells and whistles a full 2.4 and 5.0 GHz setup gives you nowadays. It’s an easy setup, nice looking, solid performing router. At $215 at the time of this writing, it is a lot more expensive than many routers from competitors that do the same job. Let’s be real, you’re not fumbling with your router all day, you set it up and forget it. If you do like to get more hands on though, you can with this offering from Linksys.
