Troubleshooting Tips
What if I can’t make an Internet connection right after
installation?
First turn your cable modem off for at least 8 seconds,
then on, to see if that fixes the problem.
Check the connections you’ve made to your cable
modem – power, Ethernet, and coax. Are those
connections good?
Check that the modem’s power cube is plugged into a
live outlet, and that the Ethernet cable is connected
securely.
Make sure that your coax cable is live. You can check that
by using it with a TV.
Check that you provided the correct setup information to
your cable service provider.
Contact your cable service provider to make sure they’ve
turned on your Internet service.
What if my cable modem has been working, then stops
working?
First turn your cable modem off for at least 8 seconds,
then on, to see if that fixes the problem.
If the modem’s lights don’t come on, check that the
modem is getting power from its power cube and that
the modem’s power button is on.
Check your cable modem cables.
Check with your service provider. Sometimes there’s a
service outage or some other service issue.
