Troubleshoot with the LEDs
When you turn on the power, the Power, LAN, and DSL LEDs should light as described here.
If they do not, refer to the sections that follow for help.
1.
When power is first applied, the Power LED lights.
2.
After approximately 10 seconds, the LAN and DSL LEDs light as follows:
a. The LAN port LEDs light for any local ports that are connected.
b. The 2.4 GHz and 5 GHz Wireless LEDs light.
c. The DSL link LED lights when there is a link through the ADSL phone lines.
d. The Internet LED lights to indicate a connection to the ISP.
Power LED Is Off
If the Power and other LEDs are off when your modem router is turned on:
•
Check that the power cord is correctly connected to your modem router and the power
supply adapter is correctly connected to a functioning power outlet.
•
Check that you are using the 12 V DC power adapter supplied by NETGEAR for this
product.
If the error persists, you could have a hardware problem and should contact NETGEAR
technical support.
Power LED Is Red
When the modem router is turned on, it performs a power-on self-test, during which time the
Power LED turns red. If the Power LED does not turn green within a minute or so or if it turns
red at any other time during normal operation, there is a fault within the modem router.
If the Power LED turns red to indicate a modem router fault, turn the power off and on to see
if the modem router recovers. If the Power LED is still red 1 minute after power-up:
•
Turn the power off and on one more time to see if the modem router recovers.
•
Clear the modem router's configuration to factory defaults as explained in
Settings
on page 149. This sets the modem router's IP address to 192.168.0.1.
If the error persists, you could have a hardware problem and should contact NETGEAR
technical support.
LAN LED Is Off
If the LAN LED for a port does not light when you connect a device, check the following:
•
The Ethernet cable connections are secure at the modem router and at the hub or device.
•
The power is turned on to the connected hub or device.
