Troubleshooting

This section provides tips for troubleshooting your cable modem in the event of minor problems. By referring to these tips, you may be able to quickly correct the problem and avoid a call to Technical Support. In addition, you should check our Web site and the Cable Modem Frequently Asked Questions (FAQs) section.

Note: If your cable modem is not responding, the first step should be to reinstall it. This may take a few minutes, but it is frequently the quickest and easiest solution.

Problem: I cannot access my Internet service or send or receive email.

Solutions:

•Check all physical connections. The SYNC, READY, and USB lights on the modem’s front panel must all be a steady green before your cable modem will work.

•Check to see that your cable TV service is working. If not, call your cable service provider.

•Verify that the C-MAC and U-MAC addresses you gave to your service provider are correct, and that they are entered into their system. See page 5.

•Check that TCP/IP is configured correctly. Refer to the section of this manual entitled Configuring Your Computer’s Network Settings on page 10. Verify that the TCP/IP parameters supplied by your cable company are correct and up-to-date.
