You can use the LEDs on the front panel of the router for troubleshooting.
Power LED Is Off or Blinking
This could occur for a number of reasons. Check the following:
•
Make sure that the power adapter is securely connected to your router and securely
connected to a working power outlet.
•
Make sure that you are using the power adapter that NETGEAR supplied for this
product.
•
If the Power LED blinks slowly and continuously, the router firmware might be
corrupted. This can happen if a firmware upgrade is interrupted, or if the router
detects a problem with the firmware. If the error persists, it is likely that a hardware
problem exists. For recovery instructions or help with a hardware problem, contact
technical support at netgear.com/support.
Power LED Stays Amber
When the router is turned on, the Power LED turns amber for up to two minutes and
then turns green. If the LED does not turn green, this indicates a problem with the router.
If the Power LED is still amber three minutes after you turn on power to the router, do
the following:
•
Reboot the router to see if the router recovers.
•
If the router does not recover, press and hold the Reset/WPS button to return the
router to its factory default settings. For more information, see Use the Reset Button
on page 114.
If the error persists, a hardware problem might be the cause. Contact technical support
at netgear.com/support.
Internet or Ethernet LEDs Are Off
If either the Internet LED or Ethernet LEDs do not light when the Ethernet connection
is made, check the following:
•
Make sure that the Ethernet cable connection is secure at the router and at the
modem that is connected to the WAN port.
•
Make sure that the Ethernet cable connections are secure at the router and at the
devices that are connected to the Ethernet ports.
