Troubleshoot with the LEDs
When you turn on the power, the LEDs light as described here:
1.
When power is first applied, the Power LED
lights red for a second and then turns
green.
2.
After about 15 seconds, the Downstream LED
, Upstream LED
, and Internet
LED
start blinking green.
3.
After about 35 seconds, the 2.4 GHz LED
lights green.
4.
After about 45 seconds, the 5 GHz LED
lights green.
5.
When the modem router establishes external connections, the following occurs:
•
After the modem router establishes a downstream connection, the Downstream
LED
lights solid amber or solid green.
•
After the modem router establishes an upstream connection, the Upstream LED
lights solid amber or solid green.
•
After the modem router establishes an Internet connection, the Internet LED
lights solid green. At this point, the modem router is ready for use.
Note:
Whether the Ethernet LED
lights depends on whether an Ethernet
device is connected to the modem router.
Power LED Is Off
If the Power LED
and other LEDs are off when your modem router is turned on, do the
following:
•
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 2.5A power adapter that NETGEAR supplied for
this product.
If the error persists, a hardware problem might exist. For recovery instructions or help with a
hardware problem, contact technical support at

Power LED Is Red
When the modem router is turned on, the Power LED
lights red for one second and then
turns green. If the Power LED does not turn green, a fault exists within the modem router. In
this situation, turn the power off and on to see if the modem router recovers. If the Power LED
still does not turn green, do the following:
•
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
to Its Factory Default Settings
113). This sets the modem router’s IP address to
192.168.0.1.
