Troubleshooting 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/T
est LED is on.
2. V
erify that the Power/Test LED turns amber within a few seconds, indicating that the self-test
is running.
3. After approximately 30 seconds, verify that:
• The Power/T
est LED is solid green.
• The Internet LED is on.
• A numbered Ethernet port LED is on 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.
• Check that you are using the 12V DC, 2.5A power adapter that NETGEAR supplied for
this product.
• If the Power/T
est LED blinks slowly and continuously, the router firmware is corrupted.
This can 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. For 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. T
urn the power off and back on to see if the router recovers.
2. Press and hold the Reset button to return the router to its factory settings.
