Troubleshooting My Internet Service Installation
28
I cannot connect to the Internet
•
Verify that the plug to your cable modem AC adapter is properly inserted into
an electrical outlet.
•
Verify that your 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 front panel LED status
indicators for your network connection 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 in How Do I Install USB Drivers,
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 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 cable modem is connected directly to the main cable input. If the cable
modem now functions properly, the cable signal splitter may be defective and
may need to be replaced.
My 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.
My cable modem does not register a cable connection
•
The cable modem works with a standard, 75-ohm, RF coaxial cable. If you
are using a different cable, your cable modem will not function properly.
Contact your 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.
•
Your USB interface may be malfunctioning. Refer to the troubleshooting
information in your USB documentation.
