Unable to Access the Internet
If the Gateway cannot access the Internet, it could be due to several reasons, such as a
failed Internet connection, a misconfigured Gateway, or a misconfigured NIC.
1. Unplug the Gateway.
Note: If the Gateway is located where you cannot easily unplug it, you can restart it using the
Restore / Reboot Gateway menu (“Restoring or Rebooting the Gateway” on page 98).
2. Turn off the Gateway for three minutes.
3. Turn off all computers attached to your network.
4. Plug in the Gateway first, turn it on, and let it boot.
5. After the Gateway completes its connection to the ISP, restart your computer.
6. Check that the Gateway’s Online LED is ON. If it is OFF, replace the coaxial cable
connecting the Gateway to the cable service. If the Online LED does not go ON after the
Gateway has been powered up for several minutes, contact your cable provider to confirm
that the service is active.
