Yes, you will have the option to customize the SSID and the passphrase.
You can try the following troubleshooting steps:
- Enter “linksyssmartwifi.com” or “192.168.1.1” in a web browser
- If your computer has a static IP Address, make sure it has valid DNS numbers. If not, set the computer to obtain an IP Address automatically. Retry Smart Setup then, if needed, reassign a static IP Address back on the computer.

The default IP Address is 192.168.1.1 and admin is the default Username and Password.
13. Which wireless band should be used to achieve a speed of up to 1300 Mbps?
The 5 GHz band is used to achieve a speed of up to 1300 Mbps.
It allows DLNA-certified devices including digital media players, gaming consoles, and digital picture frames to access video, music, and pictures that are stored on a USB hard drive that is connected to the Linksys EA6400.
There are two (2) ways to reset the Linksys EA6400 to factory defaults:

The DMZ screen allows one (1) local user to be exposed to the Internet for use of a special-purpose service such as Internet gaming and videoconferencing. DMZ hosting forwards all the ports at the same time to one computer. Port Forwarding is more secure because it only opens the ports you want to open.
- Indicator Light - Flashes slowly when powered ON, reset to factory defaults, upgrading its firmware or during a Wi-Fi Protected Setup™ (WPS) connection. When the router is ready for use, the light is continuously lit. If there is an error, the light flashes quickly.
- ETHERNET 1-4 (Yellow and Green) - The Ethernet ports connect the router to computers and other Ethernet-enabled devices on your wired network using Ethernet cables. The yellow light flashes to indicate network activity over that port. The green light turns ON when the local network port is connected to a 10/100/1000 port with auto-MDIX.
- INTERNET (Yellow and Green) - Using an Ethernet cable, the Internet port connects the router to your Internet connection, which is typically a Cable or Digital Subscriber Line (DSL) modem. The yellow light flashes to indicate network activity over that port. The green light turns ON when the Internet port is connected to a 10/100/1000 port with auto-MDIX.
- Wi-Fi Protected Setup™ (WPS) button - If you have client devices, such as wireless printers, that support Wi-Fi Protected Setup™, you can press the WPS button to automatically configure wireless security for your wireless network. To know how to connect devices using the WPS feature, click here.

The router supports six (6) connection types: Automatic Configuration - DHCP, Static IP, PPPoE, PPTP, L2TP, and Bridge Mode.
Some ISPs will require you to register your computer's MAC Address in order to access the Internet. If you do not wish to register the MAC Addresses of multiple computers with your ISP, you may assign the MAC Address that is already registered to the router using the MAC Address Clone feature. For instructions on setting this up, click here.
Select Bridge Mode if a user purchases multiple Internet IP Addresses from their Internet Service Provider (ISP) and wants those IP Addresses to pass on to devices behind the router.
5. Can I turn OFF the LEDs on the router?
Yes. Log in to your Linksys cloud account. Go to Connectivity and, under the Basic tab, turn the Port Lights OFF.
The Port Forwarding screen allows you to set up public services on your network such as web servers, FTP servers, e-mail servers or other specialized Internet applications.
Port Triggering will open ports based on the incoming port specified. Check with your software application to find out what is necessary to enter in these fields.
No. The Guest network is a separate network that ONLY provides Internet access to wireless devices. The router limits communication with other computers. It has a different password from the main network and does not allow access to files or printers within the main network.
Universal Plug and Play (UPnP) allows Windows to automatically configure the router for various Internet applications, such as gaming and videoconferencing.
The SimpleTap™ feature is a simplified way to connect your supported Near Field Communication (NFC) mobile phone wirelessly to the Linksys EA6400. The router comes with a SimpleTap™ card. You will need to download the Linksys app, then tap the card to your phone. Your phone will then connect to your router wirelessly. Your phone must have the NFC feature enabled for the SimpleTap™ feature to work. To know how to connect your Android™ smartphone using the SimpleTap™ card, click here.
NOTE: With SimpleTap™, users can take advantage of the WPS connection using the SimpleTap™ card. To learn how to connect your device using WPS in your Linksys cloud account, click here.
11. Where can I learn more about the SimpleTap™ feature?
For more information about the SimpleTap™ feature, click here.
12. Can I disable the SimpleTap™ feature on the router?
Yes. You can turn OFF the SimpleTap™ feature for NFC devices in the Wireless Tool in the user interface of the router. To know more on how to enable or disable this feature, click here. To turn off WPS, click the Wireless Tool then click the Wi-Fi Protected Setup tab. Click on the button to turn OFF the WPS connection.
Cut Through Forwarding is a new feature for Linksys Smart Wi-Fi Routers (EA6300, EA6400, and EA6700) that increases the router’s performance through bypassing protocols that add extra overhead to router processing (such as packet level inspections, sorting, filtering, and queuing).
Enabling the Cut Through Forwarding feature will only apply to devices that are NOT part of any Parental Controls or Media Prioritization policies since those devices need to be packet inspected. When disabled, there is no performance enhancement and all clients go through the extra router processing overhead.
QUICK TIP: This feature is enabled by default. Disabling this option may improve compatibility with other Wi-Fi devices and services. If you want to disable it, log in to your Linksys cloud account. Go to Connectivity > Administration. Under the Cut Through Forwarding section, uncheck the Enable checkbox.
Closing the account means erasing/deleting an email address that has a Linksys cloud account associated to it. To do this, go to the My Account section then click Close account.
NOTE: This option will only appear when you are signed in with your Linksys cloud account.
When the Linksys Smart Wi-Fi is down but the Internet is up, a new messaging will appear prompting customer to login using your Router admin password.
Yes. After applying the new IP Address, the Guest network IP scheme will automatically change to prevent conflict. For instructions on how to change the IP Address of your router using the Linksys cloud account, click here.
17. Can I add or create a Game and an Application to the Priority list that are using the same port numbers?
No. You can only add or create one Game or Application per port number to the priority list.
