Quick StartCable Modem

MB7220

Packaged with your modem

Let’s get started

If you don’t have cable modem service, please order that from your cable service provider.

Now connect your modem as shown on the next panel.

Connecting to a Coax Cable

On the next panel, you’ll need to connect your modem to a “live” coax cable. Sometimes a cable will already be available. Sometimes there’s a coax wall jack available, and you connect to the jack with a coax cable. Your modem can also share a coax cable attached to a TV by using a coax splitter.

Prepare to activate

By now you should have:

Subscribed to cable Internet service.
Connected your cable modem.
Powered up your cable modem. To do this, the On/Off button needs to be On. Wait for the green online connection light to stop flashing and remainsolidly lit. This may take up to 15 minutes.You should have a recent cable bill handy because it has your account number and you’ll probably need that.

If you’re asked for information about your cable modem, you can find this on the label on the bottom of the modem.

Activate

For some service providers, you activate by calling them. Many service providers including Comcast and Cox prefer that you activate by opening the Web browser of a computer that’s plugged into the MB7220’s Ethernet port.

For Comcast XFINITY Users Only:If the activation page does not appear in your browser, please go to www.xfinity.com/internetsetup for more information and to activate your modem.

If no registration page appears after following the browser instructions above, you need to contact your cable company to register your modem. Here is a list of phone numbers for some major cable service providers. (Note that this list is subject to change.)

Comcast – 1 (855) 652-3446Time Warner – 1 (855) 704 4503Bright House – 1 (888) 289-8988Suddenlink – 1 (877) 794-2724Cable One – 1 (877) 692 2253Cox – 1 (888) 556-1193RCN – 1 (866) 832-4726

Once your cable modem is registered either online or by phone, your service provider will provision your cable modem service. Typically this takes less than 5 minutes, but in some cases, this may take 30 minutes or longer to complete.

Once you have activated, you should have Internet access for whatever’s plugged into your cable modem. Congratulations!

If your cable modem is NOT working, see Troubleshooting Tips below.

If You Want To Connect a Router

This connection is optional, done after the cable modem is activated. A wireless router lets multiple devices (computers, smartphones, tablets, video devices, game stations…) share your cable modem’s Internet connection, either wirelessly or through a direct Ethernet connection.

1. The cable modem and the router should both be powered off.2. Plug the cable modem’s Ethernet cable into the router’s WAN port. (You may need to disconnect the cable from your computer first.)3. Power-up the cable modem. Wait for the ONLINE light to be solidly lit.4. Power-up the router. Wait for the router to complete its power-up sequence.5. The LAN light on your modem should be lit to show the Ethernet connection to your router. Follow your router’s instructions for setting up the router and connected devices.

Using a computer or other device connected to the router, try connecting to the Internet. If it works, Congratulations! Installation is complete.

Front Panel Lights

† If a blue light blinks continuously, this indicates partial service (at least one designated channel has not completed bonding). You should still get high Internet speeds, but your service provider may want to know so they can adjust their network.

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.

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.
  - If you get good speed when a computer’s plugged into the modem, you may have a router problem.
  - Some video streaming services get bottlenecked, especially at busy times like after dinner. See whether you have the speed problem at less busy times.
  - Try connecting your cable modem nearer to where the coaxial cable comes into your home. This lets you see whether your home’s cabling is a problem.
  - If you’re using a splitter with your cable modem, try the cable modem without the splitter to see if that helps. If it does, you may need to get a better splitter.

What if I’m told that my cable modem isn’t approved for my cable modem service?That’s probably not true. Leading cable service providers have a list of certified cable modems, and you can check the list for your service provider.
