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, 2.5A 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

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
