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 Linksys fully embraces the open source community and is providing open source use capabilities, they do not offer technical support on using open source firmware. Installing 3rd party firmware is done at your own risk and replacing factory-installed firmware with OpenWRT firmware will void your warranty. Please always seek the advice of more experienced users via open source community forums if you’re unsure.

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.

4 out of 5 eggsThis is a update

Pros: Speed, and great range

Cons: none so far

Other Thoughts: I had the version 1 router and it was junk, kept disconnecting and rebooting. But Linksys made good on fixing my problem. They sent me a version 2 model that replaced the old version 1. The router has been has been very reliable and fast. Linksys did go out of their way to make me happy, which they did.

1 out of 5 eggsNot like the old wrt

Pros: looks cool, brought back the old wrt look

Cons: drops all WiFi connections all day at random
drops wired connections
poor warranty

Other Thoughts: I got this product when came out, so I have a V1, since the day I bought it my WiFi would always drop in and out, no big deal, its got 2 bands so I would just switch back and forth when that happened. I thought I would be patient and wait,maybe a firmware update will fix this, Now, after is just out of the short 1 year warranty, it has been giving me wired connection issues, and both bands still drop in and out. I went to linksys forums for some kind of clarity and most people say the same thing, there is even admission by linksys techs saying that the V1 products are bad. I called and talked with them, just wanting a replacement v2, told them Id pay for shipping and even a slight premium if needed, They just offered no help, because you only have 90days for tech support, then you have to pay yearly fees to have it. or I could just buy a new one, and use this one as a paper weight. with only a 1 year on replacement and 90 days on free help they must not be to confident with the product that are making. My old wrt54g is still here working fine, after 14 years, its just not as fast. What went wrong?

5 out of 5 eggsSWEET

Pros: UPDATE: Got this router almost as soon as it came out and have had no problems since. Got a new adapter card the ASUS AC68. Had trouble with the Beta drivers (Win 10), would not connect with 5GHz but shifted to the non-Beta drivers and everything is happy now. This thing never drops and I never have to reset it. MOST stable router I have ever owned. With 3 computers, 2 smart phones, 2 tablets, thermostat, carmeras, Fire TV, cromcast and host of other things this router never skips a beat. Would buy again!

The range and speed. My old router was getting bogged down with to many things connected to it. WOW what a difference I can now walk to the street and still have signal. Before I would step out of the house and I lost signal. Everything is responding much faster. Happy with the difference this has made to my system.

Cons: Needs more ethernet ports in the back. Expensive but with gift cards I had recieved brought it down to a resonable cost so I went top notch.

Other Thoughts: UPDATE: Now I have an AC adapter card so I get 700+Mb connection in the basement on the other side of the house from the router(Upstairs).

I wanted a router I could have for many years without going obsolete quickly. The cable internet even at its highest speed is quite a bit under the top speed of this unit. The WiFi adaperter will be next because my computer will only do 300Mbs...but I'll take my time because cable will only do 110Mbs (comcast). Don't have time to play with it right now but soon I'll have time then I'll put up another review.

5 out of 5 eggsWow!

Pros: Never realized my tier III service was so fast. Had been using a modem/router; bad idea. The WRT1900AC was extremely easy to set up with the exception of my old HP P1102w which just needed new drivers (and updated 10/15 firmware if you have this printer. HP has it). Very nice to have so much control over the network. I was a full-on GNU/Linux geek for many years but I'm perfectly content with the operation of the WRT1900AC and doubt I'll fiddle it.
As already stated, it is very nice to get the absolute full benefit of 30Mbps down and 5Mbps up.

Cons: None at all and I'm very "surprised" by some of the "complaints", if ya know what I mean.

1 out of 5 eggsJUNK!

Pros: Simple interface

Cons: Drops connections
Wifi is a joke

Other Thoughts: Let me tell you this: my wife started complaining about wifi at some point. At first I thought it was my ISP's fault, but I decided to do few speed tests with my laptop using wifi and ethernet. Guess what? Ethernet works JUST FINE. Wifi sucks dirty word.

I need to find something more reliable. Are real cisco product any better? Belkin made a disaster device.

1 out of 5 eggsDon't Buy

Pros: Very fast when it works

Cons: Disconnect 5ghz at least once a day. went through 2 routers and it does the same thing. Support is a joke and not very helpful

Other Thoughts: I since bought a Asus RT-AC68U, and all my problems went away. Sad thing is my Linksys WUMC710 works better with the Asus than with Linksys router.

Manufacturer Response:

2 out of 5 eggsHas been a good router / USB 3.0 port failed after warranty

Pros: Has been a great rock solid router. No issues or complaints with current firmware.

Great range and features

Cons: USB 3.0 failed recently - about 6 months outside the warranty. It will recognize any drives but looses the drive when you try to write to it. Tried firmware and a reset, did not work. Belkin / Linksys to my shock only put a 1 year warranty on one of the most expensive routers made. Seems they did not have a lot of confidence in the reliability either

The 3.0 port was important to me so will have to sell it off, noting that it has a defective port since customer service said I was outta luck

Looks like I will be going to Asus / they appear to have a 2 year warranty at least.

Manufacturer Response:

Hi Jeremy,

Your time for sharing a review on this product is valuable to us. We understand your sentiments about the situation but rest assured your feedback for the warranty of the device will be shared to the Customer Service team. If you'd decide to try another router, we'd respect your decision.

Since we have no visibility of the steps you've tried, what we can suggest is to use another USB-ready external storage device to further isolate the challenge that you are experiencing with the USB port.

For inquiries and assistance, you may email us at We'd be happy to assist you.

2 out of 5 eggsLinksys not as good as it used to be.....

Pros: It's fast on 2.4GHz and LAN

Cons: 5GHz speed and connectivity issues

Other Thoughts: Bought this router to replace a D-Link Wireless-N router (DIR-855) and have been testing it extensively (multiple wireless configurations tested) and it's lacking. Everything works great except the 5GHz band, it's main selling point at $250+. I've tested multiple devices (laptop, desktop, smart phones) using N and AC adapters in different locations and can't get more than 4MBs transfer speeds locally. On the smart phone it stalls and hangs for a while before pushing through. The 2.4GHz band works flawlessly however. I've used the firmware that came pre-loaded as well as the latest official firmware without any change. I'm going to replace this router with the proven Netgear Nighthawk R7000. I used to own Linksys gear but since it's been bought by Belkin it's garbage. Look elsewhere for a good AC router.
I currently own a Netgear EX6200 connected to my Old D-Link DIR-855 router. On the EX6200 and DIR-855 I can get ~30Mbs+ on the 5GHz band. The WRT1900AC can't even come close to them and combined they cost less.....

Manufacturer Response:

Hi Adam,

We regret to learn about the challenges that you've had with it and we would like to offer our help in checking out the unit further and help you make it work to its full potential.
