Troubleshooting
You can find more help from our award-winning customer support at Linksys.com/support/EA7400.
Your router was not successfully set up
If Linksys Smart Wi-Fi did not complete the setup, you can try the following:
•Press and hold the Reset button on your router with a paperclip or pin until the LED
starts blinking (about 10 seconds). Install the router again.
•Temporarily disable your computer’s firewall (see the security software’s instructions
for help). Install the router again.
•If you have another computer, use that computer to install the router again.
15

Your Internet cable is not plugged in message
If you get a “Your Internet cable is not plugged in” message when trying to set up your router, follow
these troubleshooting steps.
•Make sure that an Ethernet or Internet cable (or a cable like the one supplied with your router)
is securely connected to the yellow Internet port on the back of the router and to the
appropriate port on your modem. This port on the modem is usually labeled Ethernet, but may
be named Internet or WAN.
•Make sure that your modem is connected to power and is turned on. If it has a power switch,
make sure that it is set to the ON or l (as opposed to O) position.
•If your Internet service is cable, verify that the cable modem’s CABLE port is connected to the
coaxial cable provided by your ISP.
•If your Internet service is DSL, make sure that the DSL phone line is connected to the modem’s
DSL port.
16

•If your computer was previously connected to your modem with a USB cable, disconnect the
USB cable.
•Install the router again.
Cannot access your router message
To access your router, you must be connected to your own network. If you currently have wireless
Internet access, the problem may be that you have accidentally connected to a different wireless
network.
To fix the problem on Windows computers, do the following*:
1. On your Windows desktop, click on the wireless icon in the system tray. A list of available
networks will appear.
2. Click your own network name. Click Connect. In the example below, the computer was
connected to another wireless network named wraith_5GHz. The wireless network name of the
Linksys EA7400 router, Damaged_Beez2.4 in this example, is shown selected.
3. If you are prompted to enter a network security key, type your password (security key) into the
network security key field. Click OK.
17

4. Your computer will connect to the network, and you should be able to access the router.
*Depending on your version of Windows, there could be some differences in wording or icons in these
steps.
To fix the problem on Mac computers, do the following:
1. In the menu bar across the top of the screen, click the Wi-Fi icon. A list of wireless networks will
appear. Linksys Smart Wi-Fi has automatically assigned your network a name.
2. In the example below, the computer was connected to another wireless network named
wraith_5GHz. The wireless network name of the Linksys EA7400 router, Damaged_Beez2.4 in
this example, is shown selected.
3. Click the wireless network name of your Linksys EA7400 router (Damaged_Beez2.4 in the
example).
4. Type your wireless network password (Security Key) into the Password field. Click OK.
After setup
The Internet appears to be unavailable
If the Internet has difficulty communicating with your router, the problem may appear as a “Cannot find
[Internet address]” message in your Web browser. If you know that the Internet address is correct, and
if you’ve tried several valid Internet addresses with the same result, the message could mean that
there’s a problem with your ISP or modem communicating with your router.
Try the following:
•Make sure that the network and power cables are securely connected.
•Make sure that the power outlet that your router is connected to has power.
•Reboot your router.
18

•Contact your ISP and ask about outages in your area.
The most common method of troubleshooting your router is to turn it off, then back on again. Your
router can then reload its custom settings, and other devices (such as the modem) will be able to
rediscover the router and communicate with it. This process is called rebooting.
To reboot your router using the power cord, do the following:
1. Disconnect the power cord from the router and the modem.
2. Wait 10 seconds, and reconnect the power cord to the modem. Make sure it has power.
3. Wait until the modem’s online indicator has stopped blinking (about two minutes). Reconnect
the power cord to the router.
4. Wait until the power indicator stops blinking. Wait two minutes before trying to connect to the
Internet from a computer.
To reboot your router using Linksys Smart Wi-Fi, do the following:
1. Log in to Linksys Smart Wi-Fi. (See “How to connect to Linksys Smart Wi-Fi” on page 9.)
2. Under Router Settings , click Troubleshooting .
3. Click the
Diagnostics tab.
4. Under
Reboot , click Reboot.
5. Click Yes. The router will reboot. While the router is rebooting, all connected devices will lose
their Internet connection, and will automatically reconnect when the router is ready again.
