AC1900, N900, and N450 WiFi
Cable Data Gateways
Power LED Is Off
If the Power LED and other LEDs are off when your cable data gateway is turned on, do the
following:
•
Check that the power cord is correctly connected to your cable data gateway and that the
power supply adapter is correctly connected to a functioning power outlet.
•
Check that you are using the 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 Cox Support.
Power LED Is Red (Solid or Blinking) at Any Time Other Than
While Booting
When the cable data gateway is turned on, it performs a power-on self-test, during which time
the Power LED blinks red. If the Power LED does not turn green within a minute or so, or if it
turns red (solid or blinking) at any other time during normal operation, a fault exists within the
cable data gateway.
If the Power LED turns red to indicate a cable data gateway fault, turn the power off and on to
see if the cable data gateway recovers. If the Power LED is still red one minute after
power-up, do the following:
•
Turn the power off and on one more time to see if the cable data gateway recovers.
•
Clear the cable data gateway’s configuration to factory defaults (see
Return the WiFi
Cable Data Gateway to Its Factory Default Settings
on page
94). This sets the cable data
gateway’s IP address to 192.168.0.1.
If the error persists, an unrecoverable firmware or hardware problem occurred. For recovery
instructions or help with a hardware problem, contact Cox Support.
2.4 GHz or 5 GHz LED or WiFi LED Is Off
If the 2.4 GHz or 5 GHz LED (or, for model N450, the WiFi LED) stays off, the WiFi radio in
the cable data gateway is off. For information about turning on the WiFi radio, see
Control the
WiFi Radios
on page
109. When the WiFi radio is turned on, the LED starts blinking green or
lights solid green.
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 cable data gateway and at the device.
•
The power is turned on to the connected device.
•
You are using the correct cable.
