How Do I Troubleshoot My Internet Service Installation?

I cannot connect to the Internet

•Verify that the plug to your gateway cable modem AC adapter is properly inserted into an electrical outlet.

•Verify that your gateway cable modem AC adapter is not plugged into an electrical outlet that is controlled by a wall switch. If a wall switch controls the electrical outlet, make sure the switch is in the ON position.

•Verify that the POWER, CABLE, and the appropriate indicator lights for your network connection and on the front panel of your gateway cable modem are illuminated.

•Verify that all cables are properly connected, and that you are using the correct cables.

•Verify that your cable service is active and that it supports two-way service.

•Verify that TCP/IP is properly installed and configured on all devices if you are using the Ethernet connections.

•Verify that you have followed the procedure for Installing the USB Drivers for Windows 98SE, ME, 2000, and XP, earlier in this guide, if you are using the USB connection.

•Verify that you have called your cable service provider and given them the serial number and MAC address of your gateway cable modem.

•If you are using a cable signal splitter so that you can connect the cable signal to other devices, remove the splitter and reconnect the cable so that the gateway cable modem is connected directly to the main cable input. If the gateway cable modem now functions properly, the cable signal splitter may be defective and may need to be replaced.

My gateway cable modem does not register an Ethernet connection

Even new devices do not always have Ethernet capabilities. Verify that your device has a 10/100BaseT Ethernet card and that the Ethernet driver software is properly installed. If you purchase and install an Ethernet card, follow the installation instructions very carefully.

•The gateway cable modem works with a standard, 75-ohm, RF coaxial cable. If you are using a different cable, your gateway cable modem will not function properly. Contact your cable service provider to determine if you are using the correct cable.

•You may need to renew the IP address on your PC. Refer to I need to renew the IP address on my PC, next in this section for instructions on how to renew the IP address for your particular operating system.
