Reference Manual for the Model DG814 DSL Modem Internet Gateway

If your gateway’s IP address has been changed and you don’t know the current IP address, 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 “Erase the Configuration“ on page 6-8.

Make sure your browser has Java, JavaScript, or ActiveX enabled. If you are using Internet Explorer, click Refresh to be sure the Java applet is loaded.

Try quitting the browser and launching it again.

Make sure you are using the correct login information. The factory default login name is admin and the password is password. Make sure that CAPS LOCK is off when entering this information.

If the gateway does not save changes you have made in the Web Configuration Interface, check the following:

When entering configuration settings, be sure to click the APPLY button before moving to another menu or tab, or your changes are lost.

Click the Refresh or Reload button in the Web browser. The changes may have occurred, but the Web browser may be caching the old configuration.

Troubleshooting the ISP Connection

ADSL link

If your gateway is unable to access the Internet, you should first determine whether you have an ADSL link with the service provider. The state of this connection is indicated with the WAN LED.

WAN LED Green or Blinking Green

If your WAN LED is green or blinking green, then you have a good ADSL connection. You can be confident that the service provider has connected you line correctly and that your wiring is correct.

WAN LED Blinking Yellow

If your WAN LED is blinking yellow then your gateway is attempting to make an ADSL connection with the service provider. The LED should turn green within several minutes.
