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.
ON/OFF button
POWER
Connect the supplied
power cube between
the power jack and an
electrical outlet.
RESET button
ETHERNET (LAN)
Here you can connect
a computer, router,
HDTV, game station, or
other Ethernet-
capable device.
COAX
Connect a “live” coax
cable to the modem’s
COAX connector as
discussed above.
(Tighten the nut so it’s
finger tight. You may
want to use the supplied
wrench. Make the
connection snug but not
over-tight.)
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 remain solidly 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) 652-3446
Time Warner 1 (855) 704 4503
Bright House 1 (888) 289-8988
Suddenlink 1 (877) 794-2724
Cable One 1 (877) 692 2253
Cox 1 (888) 556-1193
RCN 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.

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. You can also find information
about certifications at www.motorolacable.com/services
