Reference Manual for the Model DG814 DSL Modem Internet Gateway

Check that you are using the 18 V AC power adapter supplied by NETGEAR for this product. If the error persists, you have a hardware problem and should contact technical support.

Test LED Never Blinks or LED Stays On

When the gateway is turned on, the Test LED turns on for about 10 seconds and then turns off. If the Test LED does not turn on, or if it stays on, there is a fault within the gateway.

If you experience problems with the Test LED:

Cycle the power to see if the gateway recovers and the LED blinks for the correct amount of time.

If all LEDs including the Test LED are still on one minute after power up:

Cycle the power to see if the gateway recovers.

Clear the gateway’s configuration to factory defaults. This will set the gateway’s IP address to 192.168.0.1. This procedure is explained in “Using the Default Reset button“ on page 8-8.

If the error persists, you might have a hardware problem and should contact technical support.

Troubleshooting the Web Configuration Interface

If you are unable to access the gateway’s Web Configuration interface from a PC on your local network, check the following:

Check the Ethernet connection between your PC and the gateway as described in the previous section.

Make sure your PC’s IP address is on the same subnet as the gateway. If you are using the recommended addressing scheme, your PC’s address should be in the range of 192.168.0.2 to 192.168.0.254. Refer to “Verifying TCP/IP Properties (Windows)“ on page 3-5or “Verifying TCP/IP Properties (Macintosh)“ on page 3-8to find your PC’s IP address. Follow the instructions in Chapter 3 to configure your PC.

Note: If your PC’s IP address is shown as 169.254.x.x:

Recent versions of Windows and MacOS will generate and assign an IP address if the computer cannot reach a DHCP server. These auto-generated addresses are in the range of 169.254.x.x. If your IP address is in this range, check the connection from the PC to the gateway and reboot your PC.
