Troubleshooting Basic Functions

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 light is on.

2.After approximately 2 minutes, verify that:

•The Power light is solid green.

•The Internet light is on.

•A numbered Ethernet port light is on for any local port that is connected to a computer. This indicates that a link has been established to the connected device.

If any of the above conditions does not occur, see the following table.

Table 8-2. Troubleshooting Basic Functions

Situation	Recommended Action
Power light is off or is blinking.	• Make sure that the power cord is properly connected to your router
	and that the power adapter is properly connected to a functioning
	power outlet.
	• Check that you are using the 12V DC, 1.5A power adapter that
	NETGEAR supplied for this product.
	• If the Power light alternately blinks green every second, the router
	software 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 www.netgear.com/support.
Lights never turn off.	When the router is turned on, the lights turns on for about 10 seconds
	and then turn off. If all the lights stay on, there is a fault within the
	router.
	If all lights are still on 1 minute after power up:
	• Cycle the power to see if the router recovers.
	• Clear the router’s configuration to factory defaults as explained in
	“Restoring the Default Configuration and Password” on page 8-14.
	If the error persists, you might have a hardware problem and should
	contact Technical Support at www.netgear.com/support.
