Getting to know the Linksys EA6900 AC1900 Dual-Band Smart Wi-Fi Wireless Router

The Linksys EA6900 AC1900 Dual-Band Smart Wi-Fi Wireless Router is a simultaneous dual-band 3x3 Gigabit router with two (2) USB ports that supports a maximum of 600 Mbps on the 2.4 GHz band and up to 1.3 Gbps on the 5 GHz band.

The Linksys EA6900 comes with three (3) external antennas for better coverage and range.  This is ideal for media-centric applications such as streaming video, gaming, and Voice over Internet Phone (VoIP).


The Linksys EA6900 can create three (3) simultaneous yet separate wireless networks:

  • The 2.4 GHz Network caters to devices in your network that are 802.11n (N-only) and 802.11g (G-only) or a combination of both using Mixed mode.  The Linksys EA6900 wireless network settings include the Mixed mode which will allow backward compatibility with Wireless-B/G/N devices.

QUICK TIP:  The maximum speed that your devices can achieve with an 802.11n adapter on the 2.4 GHz band is up to 600 Mbps.

  • The 5 GHz Network will only be able to cater to devices in your network that are Mixed, N-only, and AC-only.  The Mixed mode will still allow backward compatibility for 802.11a devices.

QUICK TIP:  Connecting a device with an 802.11ac wireless adapter on the 5 GHz network that is set to AC-only will enable you to achieve up to 1300 Mbps speed.  However, by setting your network to AC-only, all other Wireless-N/G/B devices will not be able to connect.

  • The Guest Access is an additional wireless network feature that allows your visitors at home to access the Internet but not your local network (i.e., shared storage devices, printer access).

For your connected home, you may use the 2.4 GHz network to connect your wireless devices to surf the Internet and email, share files and print.  The 5 GHz network is best for heavy applications including VoIP calls, online gaming, and streaming high-definition videos.  To know more about the connected home, click here.

Linksys EA6900 features

The Linksys EA6900 has built-in USB ports that can easily add Gigabytes of storage space to your network by connecting a hard drive or USB flash disk.  The dual USB ports of the Linksys EA6900 also allow you to set up two (2) USB printers at most on your network.

You can easily set up and manage your router, device, and wireless network with Linksys Smart Wi-Fi.  Alternatively, you may opt out of a Linksys cloud account but may still be able to configure the advanced settings on your router via the Local Access link.  To know more about this feature, click here.

The Linksys EA6900 is built with security features to control and protect your router and your home network.  One of the security features on the Linksys Smart Wi-Fi Router is its software-based firewall which is IPv4 and IPv6 compatible.  These Internet Protocols have their own firewall protection, which are enabled by default.  To learn more about the Security Tool of the Linksys Smart Wi-Fi, click here.  Since this firewall has been set to prevent most programs or applications, you will have to manually configure your router’s settings to allow programs or applications you want to use by setting up Port Range Triggering.

Top panel

On the top panel of the Linksys EA6900, the KB29123-002_EN_v1.png indicator light stays steadily ON while powering up, flashes slowly during boot up, firmware upgrades, and factory reset.

NOTE:  A steady indicator light also means that a successful Wi-Fi Protected Setup™ (WPS) connection is established.  The light flashes quickly when there is a WPS error.

Below are the summary of the LEDs on your Linksys EA6900 and what each indicates:

Power / Wi-Fi Protected Setup™ (WPS)WhiteOFFPower OFF
Pulsing (0.4 Hz / 2.5 s)Booting / system self-test / firmware upgrade
Blinking (1.2 Hz / 0.8 s)WPS error or session overlap.  Up to two (2) minutes then back to solid white.
Pulsing (0.5 Hz / 1.7 s)WPS in progress.  Up to two (2) minutes.
SolidPower ON / device is ready / WPS is successful
Ethernet / LANYellow / GreenOFFNo physical link on LAN port
Flashing (yellow)Data is transmitting through LAN port
Solid (green)Physical link is up on LAN port
InternetYellow / GreenOFFNo physical link on LAN port
Flashing (yellow)Data is transmitting through LAN port
Solid (green)Physical link is up on LAN port
IMPORTANT:  In case the indicator light does not flash like any of the behavior stated above, you need to observe your connection first.  If the connection works fine, the unusual activity of the indicator light only pertains to an active network connection.  However, if you start experiencing intermittent to no connection, you may need to powercycle your router for one (1) to two (2) minutes.  If this does not fix the problem, you might need to update the firmware and reconfigure the settings of the router.

KB29123-004_EN_v1.png Adjustable External Antennas
This router is shipped with three (3) adjustable external antennas and built-in adjustable ports.  These should be connected to the router before powering it ON.  To connect the antennas, twist the antenna connector clockwise onto the antenna port on the router.

NOTE:  In order to connect to the antennas, make sure you hold them by the end of the connector (see green arrow) as you are twisting them in.  For optimal performance, the middle antenna needs to be pointed straight up and the side antennas should be angled outwards at +/- 30 degrees (see back panel screenshot).
