The Good The Linksys EA6900 Smart WiFi Wireless AC Router AC1900 sports powerful hardware to offer superfast Wi-Fi speed at close range. The router boasts a compact and practical design.

The Bad The Linksys EA6900 has a long list of issues, including an unstable 5GHz band, a nonworking USB 3.0 port, a glitchy Linksys Smart Wi-Fi cloud-based feature, and overheating. Its performance over longer range is also not as good as similarly configured routers, and there are no new features.

The Bottom Line Plagued by issues, the Linksys EA6900 Smart WiFi Wireless AC Router AC1900 is only as good as a single-band router and hence not worth its premium price.

Sporting a dual-core 800MHz processor and new Wi-Fi chip, Belkin's Linksys EA6900 Smart WiFi Wireless AC Router AC1900 is supposed one of the best routers on the market. Alas, it is not.

In my testing, the router was indeed fast; in fact, it was the fastest at close range I've seen. It offered stellar range, especially on the 2.4GHz frequency band, and it includes an easy-to-use method to remotely manage their home network via the Linksys Smart Wi-Fi Web site and mobile app.

Unfortunately, it also comes with a long list of issues, including a seemingly nonworking USB 3.0 port, a buggy mobile app, the instability of the 5GHz band, and overheating. On top of that the router doesn't have any new features compared with previous models.

All things considered, the Linksys EA6900 is still a good router, if you just want to use it as a 2.4GHz single-band router. But in this case, it's not worth its current premium price of $200. Until the above mentioned issues are worked out, for about the same amount of cash, you should get either the Asus RT-AC68U or the Netgear R7000. For more options of excellent 802.11ac routers, check out those on this list.

Familiar design, powerful hardware components
Similar to the EA6500 and the EA6400, the new EA6900 has a nice-looking design, taking the shape of an UFO with a glossy-finish top. However, the new router has three external detachable antennas coming up from its back -- previous models of the EA series use internal antennas. The router is designed to stay flat on a surface but it's also wall-mountable. Despite the external antennas, the EA6900 remains quite compact, measuring just 10.1 inches by 7.3 inches by 1.6 inches. In fact it's the most compact router of its type.

Granted, it's of a new type; it's the third router I've seen that's equipped with the new Broadcom TurboQAM Wi-Fi chip (the other two are the Asus and the Netgear mentioned above.) This chip supports the top tier (1.3Gbps) of 802.11ac on the 5GHz band and on the 2.4GHz band, offers up to 600Mbps (compared to the 450Mbps of existing Wi-Fi chips). This is because with TurboQAM technology each 2.4GHz spatial stream can deliver up to 200Mbps instead of 150Mbps. On top of that, the router is powered by a dual-core 800MHz processor. It's easily the most powerful router Belkin has offered thus far.

Top Wi-Fi speed CPU USB 3.0 support Dimensions Weight
Asus RT-N68U 1.3Gbps (5GHz) / 600Mbps (2.4GHz) Dual-core 800MHz Yes 8.7 x 6.3 x 3.3 inches 1.4 pounds
Linksys EA6900 1.3Gbps (5GHz) / 600Mbps (2.4GHz) Dual-Core 800MHz Yes 10.1 x 7.3 x 1.6 inches 1.2 pounds
Netgear R7000 1.3Gbps (5GHz) / 600Mbps (2.4GHz) Dual-Core 1000MHz Yes 11.2 x 7.3 x 2.0 inches 1.65 pounds

On the front the EA6900 has just one white LED status light in the shape of Linksys' logo. On the back it has four Gigabit LAN ports, one Gigabit WAN port, one USB 2.0 port, and one USB 3.0. You can use these ports to host either printers or external storage devices. Oddly, the router allows users to turn off its network ports' light via its Web interface, but not the status light on the front.

Also on the back, there's a little button for the Wi-Fi Protected Setup (WPS) feature and a recessed reset button. The former initiates a 2-minute window in which WPS-enabled clients can automatically connect to the router's Wi-Fi networks, and the latter brings the router back to its default manufacturer settings.

Very easy to set up, glitchy Linksys Smart Wi-Fi cloud feature
Like the rest in the Linksys EA series, the Linksys EA6900 is very easy to set up. By default, the router comes preset with a Wi-Fi network and a password, the information for which you can find printed on the router's underside. While there's only one set of information, the router actually comes with two Wi-Fi networks, one for each of its wireless bands (2.4GHz and 5GHz), but both share the same name and password. And in most cases, this is all you need to get your home network up and running. All you have to do is plug the router into power and connect its WAN (Internet) port to an Internet source, such as a cable modem.

If you want to customize the settings, such as changing the Wi-Fi network's name and password, or using the router's other features, then you need to use its Web interface. To get to the router's Web interface from a connected device, just point a browser to, or to its default IP address, which is The router's default log-in password is admin.

At the log-in page, you also have the option of creating a Linksys Smart Wi-Fi account and adding the router to that account (by typing in the router's log-in password). If you choose to do so, from then on, you'll be able to access the router's Web interface even when you're not using a computer in the same network that's hosted by the router. In other words, once your account is created, you can just go to from any Internet-ready computer and manage your home network when you're out and about. On top of that you can also use a sizable collection of mobile apps to manage the router's settings and features, again, via the Internet.

In my trial, I created a new account and associated the review unit with this account. Later on, I was able to use the Linksys Smart Wi-Fi Web site to manage the network remotely. However, when I used the Linksys Smart Wi-Fi mobile app, it wouldn't accept my log-in information. On the other hand, the account that I had created before while reviewing the EA6400 worked well with the mobile app, but wouldn't work with the Linksys Smart Wi-Fi Web site. This was likely caused by the fact that Linksys is still transitioning from Cisco to Belkin; hopefully this glitch will be fixed in a near future.

When things were working, locally or via the Internet, the EA6900's Web interface always worked well. It's also very responsive and well-organized.

No new features, nonworking USB 3.0 port
The EA6900 has about the same features found in the EA6500 router. It's a top-tier true dual-band router that offers up to 1.3Gbps Wi-Fi speed on the 5GHz band and up to 600Mbps on the 2.4GHz band (as opposed to just 450Mbps of the EA6500). As the way Wi-Fi works, you only get these top speeds with compatible clients. All existing clients, however will work with the router at their respective cap speed. And all can enjoy the router's extra long range.

Other than that the router has no new features at all. In fact it has exactly the same as what the EA6500 has to offer, inlcuding the shortcomings. For example its Guest Access feature is still available only on the 2.4GHz band, and you can't change the name of this guest network. It still takes the name of the main network and add the "-guest" suffix to it. This means you have to reveal your main network's name to guests, up to 50 of whom are supported.

The two main features of the router are Media Prioritization list or a Parental Control list. The former is a convenient quality-of-service (QoS) feature that allows you to prioritize Internet traffic to certain connected clients; the latter, as the name suggests, is for when you want to restrict access to the Internet to certain clients.
