N600 Wireless Dual Band Router WNDR3400v3
Troubleshoot with the LEDs
After you turn on power to the router, the following sequence of events should occur:
1. When power is first applied, verify that the Power/Test LED
is lit.
2. Verify that the Power/Test LED turns amber within a few seconds, indicating that the self-test
is runnin
g.
3. After approximately 30 seconds, verify:
• The Power/Test LED is solid green.
• The Internet LED is lit.
•
A numbered Ethernet port LED
is lit for any local port that is connected to a computer.
This indicates that a link has been established to the connected device.
The LEDs on the front panel of the router can be used for troubleshooting.
Power/Test LED Is Off or Blinking
• Make sure that the power cord is securely connected to your router and that the power
adapter is securely connected to a functioning power outlet.
• Make sure that you are using the 12V DC, 2.5A po
wer adapter that NETGEAR supplied
for this product.
• If the Power/Test LED blinks slowly and continuously, the router firmware is corrupted.
This ca
n happen if a firmware upgrade is interrupted, or if the router detects a problem
with the firmware. If the error persists, you have a hardware problem. tFor recovery
instructions or help with a hardware problem, contact technical support at

Power/Test LED Stays Amber
When the router is turned on, the Power/Test LED turns amber for about 20 seconds and
then turns green. If the LED does not turn green, the router has a problem.
If the Power/Test LED is still amber 1 minute after you turn on power to the router:
1. Turn the power off and back on to see if the router recovers.
2.
Press and hold the Res
tore Factory Settings button to return the router to its factory
settings. See Factory Settings on p
age 110.
If the error persists, you might have a hardware problem and should contact technical support
at www.netgear.com/support.
LEDs Never Turn Off
When the router is turned on, the LEDs light for about 10 seconds and then turn off. If all the
LEDs stay lit, the fault is within the router.
