Make sure that your computer's IP address is on the same subnet as the gateway. If you
are using the recommended addressing scheme, your computer's address should be in
the range of 192.168.0.10 to 192.168.0.254.
Note:
If your computer's IP address is shown as 169.254.x.x:
Recent versions of Windows and Mac OS 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 computer to
the gateway and reboot your computer.
•
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 sets the gateway's IP
address to 192.168.0.1. For more information, see

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 might have
occurred, but the web browser might be caching the old configuration.
Troubleshoot the ISP Connection
If your gateway is unable to access the Internet and your Internet LED is on, you might need
to register the cable MAC address or device MAC address of your gateway with your cable
service provider.
Additionally, your computer might not have the gateway 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. For more information, see
on page 42.
Troubleshoot a TCP/IP Network Using a Ping Utility
Most TCP/IP terminal devices and routers contain a ping utility that sends an echo request
packet to the designated device. The device then responds with an echo reply. You can
