CM400 High Speed Cable Modem
If the cable modem does not save changes you made, do the following:
•
When entering configuration settings, be sure to click the
Apply
button before moving to
another screen, or your changes are lost.
•
Click the
Refresh
or
Reload
button in the web browser. The changes occurred, but the
web browser might be caching the old configuration.
Troubleshoot the Cable Internet Connection
If your cable modem cannot access the Internet but the Internet LED
lights green,
register the cable MAC address or device MAC address of your cable modem with your cable
Internet provider (see
Contact Your Cable Internet Provider and Set Up Internet Service
on
page
