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.
