Troubleshoot with the LEDs
When you turn on the power, the Power, LAN, and DSL LEDs 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 solid red.
2. After approximately 10 seconds, the LAN port LED lights green
for any local ports that
are connected.
3. After approximately 1 minute, the DSL link LED lights green
to indicate that a DSL link is
established.
4. After approximately one minute, the Power LED turns solid green
.
Power LED Is Off
If the Power and other LEDs are off when your modem router is turned on:
Check that the On/Off button on the back panel is in the On position, that is, it is pushed
in.
Check that the power cord is correctly connected to your modem router and that the
power supply adapter is correctly connected to a functioning power outlet.
Check that you are using the 12 VDC 1A power adapter supplied by NETGEAR for this
product.
If the error persists, you might have a hardware problem. For recovery instructions, or help
with a hardware problem, contact technical support at www

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 one 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 (see Side Panel with Restore
Factory Settings Button on page 12).
This sets the modem router’s IP address to
192.168.0.1.
If the error persists, you have a hardware problem. For recovery instructions, or help with a
