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.
