Action

LED Behavior

• Make sure that the power adapter is securely connected to your cable

modem and a functioning power outlet.

• Check that you are using the power adapter from NETGEAR for this

product.

• If the error persists, a hardware problem occurred. Contact technical

support.

All LEDs are off when the cable modem
is plugged in.

• Reset the configuration of the cable modem to its factory defaults.

• If the error persists, a hardware problem occurred. Contact technical

All LEDs stay on.

• Make sure that the Ethernet cable connections are secure at the cable

modem and at the computer, router, or WiFi router.

• Make sure that power is turned on to the connected hub or computer.

Internet service. Your ISP can verify that the signal quality is good
enough for cable modem service.

• Remove any excessive splitters that you installed on your cable line.

Run a “home run” back to the point where the cable enters your
home.
