Let’s get started
If you don’t have cable Internet service, please order that from
your cable service provider. MG8702 supports DOCSIS 3.1, the
fastest cable modem service standard. Your MG8702 also
supports all speeds of any DOCSIS 3.0 services.
Now connect your MG8702 as shown on the next panel.
Connecting to a Coax Cable
Please see the connection photo on the next panel. You
connect your MG8702 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 MG8702 can also share a coax cable
attached to a TV by using a coax splitter. Please note
that a badly chosen splitter reduces a cable modem's
speed; so if you need to use a splitter, use a 2-way
splitter whose top frequency is 1,000 MHz or higher.

between
the power jack and an
electrical outlet.

Prepare to activate
By now you should have:
•Subscribed to cable Internet service.
•Connected your MG8702.
•Powered up your cable modem/router. To do this, the On/Off
button needs to be On (Push the button in until it clicks). Wait
for the online connection light ( for 3.0, or for 3.1) 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 the MG8702, you can
find this on the label on the bottom of the modem/router.
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 one of the MG8702’s Ethernet ports. Once
you've opened the browser, try to go to www.motorola.com .
This should bring you to the service provider's activation
page.
If you don’t have a computer, you can use the Web browser of
a WiFi device such as a smartphone or tablet for activation. In
that case you’ll need the unique Wireless Network Name and
Password printed on the bottom of your MG8702. You’ll use
these in setting up your wireless device to connect to the
MG8702. Once you’ve connected, you can open the browser
of that wireless device.

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

Once your MG8702 is activated either online or by
phone, your service provider will provision your
MG8702 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, try to browse the Web using a
device connected via Ethernet or WiFi to the MG8702. (See
the section Wireless Router, below for information on
connecting via WiFi). If browsing works, Congratulations!
Your MG8702 is working.
If your MG8702 is NOT working, see Troubleshooting Tips
below.

Configuration Manager
You may not need to use the MG8702’s Configuration
Manager. Here are some reasons for using it:
•You want to change the wireless network name and password.
For instance, maybe you want a more easily remembered
name, or you're replacing a router and want to use your
existing WiFi Network Name (SSID) and/or WiFi
Password/Key instead of the unique ones that come with the
MG8702. (See WiFi setup page.)
•You want to set up special Internet gaming settings.
•You want to get performance information about the MG8702
modem and/or built-in router. This can be helpful in
diagnosing DOCSIS performance issues and/or optimizing
wireless performance.
If you need to access the MG8702 Configuration Manager,
open your Web browser. Type http://192.168.0.1 in the
address bar and press the Enter key.
In the login dialog box, type the following User Name and
Password in lower case, then click OK.
User Name: admin
Password: motorola
The Basic Status and Settings page will appear. If this page
doesn’t appear, please see the Troubleshooting Tips below.
You can get more detailed information about the MG8702 and
its Configuration Manager, please see

Wireless Router
As noted before, the MG8702 has a unique Wireless Network
Name/SSID and Wireless Security Key/Password printed on
the MG8702’s bottom label. Set up your wireless devices to
work with this SSID and security key, or the SSID and security
key you specified, if you changed them.
Note that wireless performance depends on a number of
factors. Please keep these things in mind:
•Where possible, put the MG8702 in a central place so that it’s
not too far away from your other wireless devices.
•Try to avoid interference from other wireless devices such as
Bluetooth headsets and stereos, microwave ovens, WiFi-
capable printers, and 2.4 GHz cordless phones and base
stations. Don’t put the MG8702 close to these interfering
devices.
•Sometimes it helps to change the MG8702 wireless channel
frequency to reduce interference with neighbors’ wireless
networks. This is discussed in the Troubleshooting section of
this Quick Start.
•Wireless range can be limited by a variety of issues, including
weak wireless clients and challenging building configurations.
Some devices that connect to the MG8702 do not have as
powerful a wireless signal, and often those devices can slow
down your network’s WiFi. If you need greater wireless range
far away from your MG8702, you could add a Range Extender.
For more information, please see
www.motorolanetwork.com/extenders
If you have coaxial cable running near your router and a
distant wireless access point, HDTV, or other device, MoCA is
often a good way to connect the router to the device. MoCA
can share the same cable used for cable TV or cable Internet.
With the Motorola MM1000 MoCA Adapter, speeds are up to
1,000 Mbps. Please see
www.motorolanetwork.com/MocaWifi

WiFi setup if you want to keep your
current network name and password
If your Motorola modem/router is replacing a modem/router
or router with WiFi capability, we strongly recommend that
you keep using the original WiFi network name (SSID) and
password that you were using on the modem/router or router
that you’re replacing. This will allow all your WiFi devices to
keep working without a new WiFi setup. If possible, do this
configuration by connecting a computer with Ethernet to any
of your Motorola modem/router’s Ethernet ports. You can also
do this configuration by using your smartphone or another
WiFi device that has a Web browser.
1. First write down the wireless network name and
password for your original network. Most WiFi devices
work on either the 2.4 GHz band, or both the 2.4 GHz and
the 5 GHz band. You may a wireless network name and
password for just the 2.4 GHz band; or you may have a
wireless network name and password for both the 2.4
GHz and 5 GHz bands.
2. Now open the browser of the computer or WiFi device
that you’re using to configure the Motorola
modem/router. Type http://192.168.0.1 in the address bar
and then press the Enter key. You will see a login screen
If you need to do this configuration by using your
smartphone or other WiFi device, first complete a WiFi
setup for your new modem/router, using the wireless
network name (SSID) and password printed on the
modem/router’s bottom label. See the Quick Start Guide
for more details. (You don’t need an Internet connection
to do this.)

where you should enter the following information in lower
case, then click OK.
User Name: admin
Password: motorola
3. After you click OK, the Basic Status page should appear.
Enter the Wireless Network Name and Password for the
2.4 GHz band for your original network, making sure to be
accurate and to use the same upper and lower case
characters you used for your original network. Then enter
the Wireless Network Name and Password for the 5 GHz
band you’ve been using, if any. If you haven’t been using a
5 GHz band and your Motorola modem/router has a 5
GHz band, here’s a good way to pick a network name and
password. If your 2.4 GHz band wireless network name is
smith, call your 5 GHz band smith-5 . Use the same
password for both your 2.4 and 5 GHz bands.
4. Press Save once you’ve entered the required information.
Now your new settings should be saved, and they should
be as close to your original wireless network name and
password settings as possible. If you see a message
saying that you lost your Internet connection, ignore it.
Now go to your device’s WiFi setup page. There you can
select your original 2.4 GHz network name or you can
select the similar name for 5 GHz. Your password is the
same one you’ve been using for your original network. All
your other WiFi devices should continue to work.
If you have a problem, you can restore the factory
modem/router network names and passwords by pressing
the Reset button on the back of the modem/router. Those
names and passwords are printed on the bottom label of your
modem.
