Let’s get started
1Call your cable service provider to order cable Internet service if
you don’t already have it. Mention that your MG8702 supports
DOCSIS 3.1, the fastest cable modem service standard. Your
MG8702 also supports the top speeds of any DOCSIS 3.0 services.
If you already have cable Internet service, you probably don’t need
to call your cable service provider. You should have your account
number handy in case you need it during the activation process. You
can generally find the account number on the landing page when
you log in to your cable service provider account. You can also find
it on a recent cable bill.
2If possible, use your smartphone to take a photo of the label on
the bottom of your cable modem. You’ll need the information on
the label later. It will help to print the photo so you can scan a QR
code on the label later.
3 Disconnect existing modems and routers, if any. Now connect
your MG8702 as shown on the next page.
Connecting to a coax cable
See the connection photo on the next panel. 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 may reduce a
cable modem's speed or prevent connection to the network: if
you need to use a splitter, use a two-way splitter whose top
frequency is 1,000 MHz or higher.

USB 3.0 Port
WPS button
WLAN button
WiFi on/off button
RESET
If pressed for ten
seconds all settings will
revert to factory
defaults.
ETHERNET (LAN 1-4)
You can connect a
computer, smart TV,
game station, or other
Ethernet-capable device
to any of these 4 LAN
ports.
COAX
Connect a “live” coax
cable (not included) to
the modem’s COAX
connector as discussed
above. Use the wrench
to tighten the nut
finger-
tight
: Do not
overtighten.
ON/OFF button
POWER
Connect the supplied
power adapter between
the power jack and an
electrical outlet.

Prepare to activate
Power 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.
Activate with your service provider
Some service providers allow you to activate by calling them. Others,
like Comcast Xfinity and Cox, prefer that you activate by opening the
Web browser of a computer. It’s best if the computer is plugged into
one of the MG8702’s Ethernet ports, but connecting with WiFi also
works as discussed below.
Once you've opened the browser, go to your service provider’s web
page. This should bring you directly to the service provider's activation
page. Follow the onscreen instructions.
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 WiFi Network Name (SSID) and WiFi Password printed
on the bottom of your MG8702. You’ll use these in setting up your
wireless device to wirelessly 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 or call
1 [phone] to activate your modem.
Here is a list of phone numbers for some major cable
service providers.

If you’re asked for information about the MG8702, refer to the photo
you took of the label on the bottom of the modem/router. A sample
label is shown below. The information highlighted in yellow below will
be unique on your product’s label. The unique QR code on the right
side of your label will help you with activation using our MotoManage
app.
When your MG8702 is activated either online or by phone, your service
provider will provision your MG8702 service. This usually takes less
than five minutes, but sometimes takes 30 minutes or longer.
Once the MG8702 is fully 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.

MotoManage
We strongly suggest that you download our MotoManage App from
the Apple App Store or from Google Play to access basic and advanced
network control features. The app lets you manage your network
quickly and easily, and it makes it easy to keep your network’s original
wireless settings (recommended for most people unless the original
network name was 5 or less characters or the wireless password was 7
or less characters).
The app includes basic and advanced features, which are all available
free of charge for the first month. After that you will be able to decide
whether you’d like to just keep the free basic features, or whether you’d
like to also keep the advanced features for a small monthly fee.
1Download the MotoManage app on your smartphone or
tablet.
2Open the app and create an account.
3Scan the QR code on the bottom of your MG8702 (or scan it from
the photo you printed) to join your device’s WiFi network.
4Now enjoy the app. You can easily elect to keep your original name
and password, as we recommend.
a. Or, maybe you want to change the WiFi Network Name and
password. For instance, you might prefer a password that’s
easier to remember, 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.
b. Plus you can easily monitor your Internet usage and WiFi
signal strength, get security alerts that help protect your
network, control Internet access by devices, or set up some
basic parental controls.
Note that your MG8702 must be online for the app to communicate
with it.

Configuration Manager
The Configuration Manager is an alternative method to control WiFi
settings and other options if you have not downloaded the app. The
Configuration Manager also includes some additional device settings
for the advanced user as discussed below. Most users don’t need to use
the Configuration Manager if they use the Network Management App.
You might need to use the Configuration Manager if:
•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 optimizing wireless performance.
•You want to set up a Virtual Private Network (VPN).
•You want to change the wireless network name and password without
using the App. (See WiFi setup page.) Note that these WiFi settings
can be changed in the app without having to log in to the
Configuration Manager.
If you need to access the MG8702 Configuration Manager, open your
Web browser. Type https://192.168.0.1 in the address bar, and press
Enter. You will see security warnings. You can safely ignore these and
click through to access the Configuration Manager (see Note below). In
the login dialog box, type the following username and password in
lower case, then click OK.
Username: admin
Password: <unique password printed on modem’s label>

When you log in for the first time the first time Wireless Setup screen
will appear. (If you have already connected using the MotoManage app,
this screen may not appear). If this screen doesn’t appear, please see
the Troubleshooting Tips below. (See below under WiFi Setup if you
want to keep your current network name and password and if you
haven’t used the app to do that.)
NOTE:
To reduce the risk of unauthorized access, your MG8702 is
designed to accept access via
secure http
(https)
only
. To
support secure access, your MG8702 includes a self-signed
certificate. Unfortunately, web browsers flag self-signed
certificates as insecure.
This means that if you open the MG8702 Configuration Manager,
your browser will display warnings that the site is insecure. The
MG8702 Configuration Manager is secure, so you can safely
ignore those warnings
.
For more detailed information about the MG8702 and its Configuration
Manager, please see www.motorolanetwork.com/MG8702manual.

WiFi Setup using the Configuration Manager
Use this section only if you want to keep your current network name and
password and for some reason you can’t use the App.
We strongly suggest that you do this by using the MotoManage App
mentioned above. If that’s not possible, please continue below.
Please note that if your previous network name was 5 or less characters
or the wireless password was 7 or less characters, you cannot change
the Motorola password to match your previous network.
If possible, connect a computer with Ethernet to any of your
modem/router’s Ethernet ports. You can also do this configuration
using WiFi by using your smartphone or another WiFi device that has a
Web browser.
1Now 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 have 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.
2If you haven’t already logged into the Configuration Manager, follow
the steps in the section above labeled Configuration Manager to do
so.
If you need to do this WiFi setup by using your smartphone or
other WiFi device, first connect your WiFi device to your new
modem/router using the wireless network name (SSID) and
password printed on the modem/router’s bottom label. (You don’t
need an Internet connection to do this.)

3After you click OK, the Wireless Initial Setup page should appear.
Follow the instructions on this page to enter the network name and
password 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.
4Press Save. You will see a screen confirming your settings. If you
need to, you can correct the settings and press Save again.
If you encounter a problem, you can restore the factory modem/router
network name and password by pressing the Reset button on the back
of the modem/router for 10 seconds (a paperclip helps). Those names
and passwords are printed on the bottom label of your MG8702 (and
on the photo you took with your phone).

Wireless Router Performance
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. For example, in a two story
house, an ideal location may be towards the middle of the first floor
close to the ceiling.
•Avoid placing the MG8702 near metallic objects such as filing cabinets
or appliances. Also avoid placing it on or near metallic shelves.
•Try to avoid interference from other wireless devices such as Bluetooth
headsets and stereos, microwave ovens, wireless 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 issues like weak wireless clients and
challenging building configurations. Some devices that connect to the
MG8702 may not have a powerful wireless signal, so those devices may
slow down your network’s WiFi. If you need greater wireless range far
away from your MG8702, you could add a Range Extender.
•If you have coaxial cable running near your router and a distant
wireless access point, Smart TV, or other device, a Motorola MoCA
Adapter 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 and
features speeds up to 2,500 Mbps. Please see
www.motorolanetwork.com/MocaWifi

USB 3.0 Port
A USB 3.0 port is located on the back of the MG8702. You can choose
to use this port for File Sharing by the devices on your local network.
1Log in to the Configuration Manager (see Configuration Manager
section above) Navigate to Advanced > Advanced Router > File
Sharing. If it isn’t already checked, click the Enable checkbox for
Windows File Sharing (SAMBA), and click Save.
2Plug your USB flash drive into the MG8702 USB port.
3In Windows: Make sure you have Network Discovery and File
Sharing enabled in Network Sharing on your computer.
Open File Explorer (Windows Explorer) and type \\192.168.0.1 in the
address bar. Press Enter. This will open your USB flash drive
directory. Then you will have read/write access to its content.
In MacOS: On the Finder menu, navigate to Go > Connect to
Server. In the address bar type smb://192.168.0.1 and then press the
Enter key.
If prompted by an authentication dialog box, select Guest and click
Connect.
Then click OK. This will open your USB flash drive directory. Then
you will have read/write access to its content.
