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? Be sure that the coax cable connection is tight enough, possibly using the coax wrench. • 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, and 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. Sometimes a service outage also affects your TV service, so check that. What if I'm getting Internet service but my speed is disappointing? • Be sure you know what speed you're paying for. • Check the speed with a computer plugged into the modem. Use one of the tools found when you search the phrase: broadband speed test. 9
