• Make sure that the IP address of your computer is on the same subnet as the gateway. If
you are using the recommended addressing scheme, the address of your computer is in
the range of 192.168.0.10 to 192.168.0.254.
Note: If the IP address of your computer is shown as 169.254.x.x:
Recent versions of Windows and Mac OS generate and assign an IP
address when the computer cannot reach a DHCP server. These
autogenerated addresses are in the range of 169.254.x.x. If your IP
address is in this range, check the connection from the computer to
the gateway and reboot your computer.
• If the IP address of your gateway has been changed and you do not know the current IP
address, clear the configuration of the gateway to its factory defaults. This operation sets
the IP address of the gateway to 192.168.0.1. For more information, see
Settings on page 72.

Internet Explorer, click the Refresh button to make sure that the Java applet is loaded.
• Try quitting the browser and launching it again.
• Make sure that you are using the correct login information. The gateway user name is
admin and the default password is password. Make sure Caps Lock is off when you enter
this information.
If the gateway does not save changes you have made, check the following:
• When entering configuration settings, be sure to click the Apply button before moving to
another screen, or your changes are lost.
• Click the Refresh or Reload button in the web browser. The changes have occurred, but
the web browser might be caching the old configuration.

Troubleshoot the ISP Connection

When your gateway is unable to access the Internet and your Internet LED is on, register the
cable MAC address or device MAC address of your gateway with your cable service provider.
Additionally, your computer does not have the gateway that is configured as its TCP/IP
gateway. If your computer obtains its information from the gateway by DHCP, reboot the
computer and verify the gateway address.

Troubleshoot a TCP/IP Network Using the Ping Utility

Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request
