AC1900 Cable Modem Voice Router
Troubleshoot with the LEDs
You can use the LEDs on the front panel of the modem router for troubleshooting.
Power LED Is Off
• Make sure that the power cord is securely connected to your modem router and securely
connected to a working power outlet.
• Check that you are using the power cord that NETGEAR supplied for this product.
• If the problem persists, contact technical support for help at www.netgear.com/support.
LEDs Never Turn Off
When the modem router is turned on, the LEDs light for about 10 seconds and then turn off.
If all the LEDs stay on, this indicates a fault within the modem router.
If all LEDs are still lit one minute after power-up, do the following:
1. Cycle the power to see if the modem router recovers.
2. Press and hold the Reset button to return the modem router to its factory settings. For more
information, see
Factory Settings on page 124.
If the error persists, a hardware problem might exist. Contact technical support at
netgear.com/support.
Internet LED Is Off
If the Internet LED is off and the modem router is connected to the cable television cable, try
the following:
• Make sure that the coaxial cable connections are secure at the modem router and at the
wall jack.
• Make sure that your cable Internet provider provisioned your cable Internet service. Your
provider can verify that the signal quality is good enough for modem router service.
• Remove any excessive splitters that on your cable line. Run a “home run” back to the
point where the cable enters your home.
Troubleshoot the Cable Internet Connection
When your modem router cannot access the Internet and your Internet LED is on, register
the cable MAC address or device MAC address of your modem router with your cable
Internet provider.
Additionally, check to make sure that the setting for your computer’s TCP/IP gateway is set to
use the modem router. If your computer obtains its information from the modem router by
DHCP, reboot the computer and verify the gateway address.
