Troubleshoot with the LEDs
After you turn on power to the wireless modem router, the following sequence of events
should occur:
1. When power is first applied, verify that the Power LED
is on.
2. V
erify that the Power LED turns red within a few seconds, indicating that the self-test is
running.
3. After approximately 30 seconds, verify that:
• The Power 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 wireless modem router can be used for troubleshooting.
Power LED Is Off or Blinking
• Make sure that the power cord is securely connected to your wireless modem 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 LED blinks slowly and continuously
, the wireless modem router firmware is
corrupted. This can happen if a firmware upgrade is interrupted, or if the wireless modem
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 www.netgear.com/support.
Power LED Stays Red
When the wireless modem router is turned on, the Power LED turns red for about 20 seconds
and then turns green. If the LED does not turn green, the wireless modem router has a
problem.
If the Power LED is still red one minute after you turn on power to the wireless modem router:
1. Turn the power off and back on to see if the wireless modem router recovers.
2. Press and hold the Restore Factory Settings button to return the wireless modem
router to its factory settings. See Factory Settings on page 142.
If the error persists, you might have a hardware problem and should contact technical
support at www.netgear.com/support.
