LET’S GET STARTED
1. If you don’t have cable Internet service, please call your cable
service provider to sign up. Mention that your MG8702 device
supports DOCSIS 3.1, the fastest cable modem service standard
available, as well as the top speeds of any DOCSIS 3.0 service.
2. Disconnect any existing modems and routers on your network.
CONNECTING TO A COAX CABLE
Connect your MG8702 device to a “live” coax cable (see image on next
page). A cable may already be available to you, or a coax wall jack may
be nearby to connect one to. Your MG8702 device can also share a coax
cable attached to a TV by using a coax splitter.
Note: 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 with a top frequency of 1,000 MHz or higher.

SMART WIFI,
HAPPIER HOME
Your device is powered by the Minim
App, which enables you to:
• Personalize your system settings
• Test your device speeds and signal
• Secure your privacy and data
• Assign devices to family profiles
• Set schedules, content filters, safe
search

CONFIGURATION MANAGER
The Configuration Manager is an alternative method of adjusting your
WiFi and device settings. We strongly suggest that you do this by
using the Minim App. However, you may need to use the Configuration
Manager if:
• You want to change the wireless network name and password
without using the App. For instance, maybe you want a password
that’s easier to remember, or you want to use your existing WiFi
Network Name (SSID) and/or WiFi Password/Key instead of the
unique ones that come with the MG8702 device. (See WiFi setup
page).
• You want to set up special Internet gaming settings.
• You want to get performance information about the MG8702 device
modem and/or built-in router. This can be helpful in diagnosing
DOCSIS performance issues and optimizing wireless performance.

WIRELESS ROUTER PERFORMANCE
Note that wireless performance depends on a number of factors. Please
keep these things in mind:
• Where possible, place the MG8702 device in a central location so it
can connect to your other wireless devices.
• Try to avoid high interference by keeping the MG8702 device away
from Bluetooth headsets and stereos, microwave ovens, wireless
printers, and 2.4 GHz cordless phones and base stations.
• Sometimes it helps to change the MG8702 device 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 device do not have as powerful a wireless signal,
so those devices may slow down your network’s WiFi. If you need
greater wireless range far away from your MG8702 device, 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 1,000 Mbps. Please see www.
motorolanetwork.com/MocaWifi.

13
USB 3.0 PORT
A USB 3.0 port is located on the back of the MG8702, which can be
used for File Sharing by the devices on your local network.
1. Log 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.
2. Plug your USB flash drive into the MG8702 device USB port.
3. In 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, giving you access to read/
edit 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 Enter. If
prompted by an authentication dialog box, select Guest and click
Connect, then OK. This will open your USB flash drive directory,
giving you access to read/edit its content.

TROUBLESHOOTING TIPS
What if I can’t make an Internet connection right after
installation?
1. Turn the modem that provides your Internet connection o for at
least 10 seconds, then on, to see if that fixes the problem.
2. Check the connections you’ve made to your device. Power and
coax connections are required, and up to 4 Ethernet connections
are optional. Are those connections strong? Be sure that the coax
cable connection is tight enough, possibly using the coax wrench to
carefully tighten a bit more.
3. Check that the device’s power adapter is plugged into a live outlet,
and that the Ethernet cable is connected securely.
4. Make sure that your coax cable is live. You can check that by using it
with a TV.
5. Check that you provided the correct setup information to your cable
service provider.
6. Contact your cable service provider to make sure they’ve turned on
your Internet service.
What if my MG8702 device has been working, then stops
working?
1. Turn your MG8702 device o for at least 8 seconds, then on, to see if
that fixes the problem.
2. If the MG8702 device’s lights don’t come on, check that the modem
is getting power from its power adapter and that the MG8702
device’s power button is on.
3. Check your MG8702 device cables.
4. Check with your service provider. Sometimes there’s a service

16
outage or some other service issue. Sometimes a service outage also
aects your TV service, be sure to check that as well.
What if I am connected wirelessly, but my connection seems slow
or keeps dropping?
1. Be sure you know what speed you’re paying for.
2. Check your Minim App to view each device’s speed and WiFi signal
strength and to run Internet speed tests to check for bottlenecks.
3. If you don’t have the app, check the speed with a computer plugged
into one of the modem’s Ethernet ports. Use one of the tools found
when you search the phrase: broadband speed test.
4. Make sure your computer’s LAN port supports gigabit rates (1000BT
or GE). You will need this LAN port speed if you want that computer
to achieve service speeds of 100 Mbps or greater.
5. If you get good speed when your computer is plugged into the
modem, you may have a wireless problem. In that case, please re-
read the wireless router section.
6. Some video streaming services get bottlenecked, especially at busy
times such as after dinner. See whether you have the speed problem
at other times.
7. Try connecting your MG8702 device nearer to where the coaxial
cable comes into your home. This lets you see whether your home’s
cabling is a problem.
8. If you’re using a splitter with your MG8702 device, try the MG8702
device without the splitter to see if that helps. If it does, you may
need to get a better splitter, one with a top frequency of at least
1,000 MHz.

17
How do I check to see if my cable modem is approved by my
cable service provider?
1. Leading cable service providers have a list of certified cable modems
for each of their Internet speeds.
2. You can check the list for your service provider or find more
information about certifications at www.motorolanetwork.com/
services
What if I don’t know my MG8702 device’s Wireless Network
Name/SSID or Security Key/Password?
1. Refer to the photo you took of the label on the bottom of your
router. It shows the default values for you to use. If you changed
these credentials, try to remember where you put the new values.
2. If you have a device that connects wirelessly to the MG8702 device,
it may show the Wireless Network Name/SSID and Password. You
can also find this information in the MG8702 device Configuration
Manager. (See Configuration Manager section above.)
3. If all else fails, reset the device to factory defaults by holding the
Reset button for 10 seconds. (A paperclip helps.) You can then use
the default values.
What if the first time Wireless Setup screen does not appear in
Configuration Manager after changing my name/password?
1. If you encounter 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 for 10 seconds using a paperclip.

18
What if I think that wireless devices are interfering with my
MG8702 device wireless router?
1. First, make sure that your MG8702 device has been placed as far
away from interfering devices — like Bluetooth transmitters and
neighboring WiFi routers — as possible. Then, try to pick a lesser-
used wireless channel for your MG8702 device by going into your
MG8702 device’s Configuration Manager.
2. Click the Advanced button at the top of the page, then click the
Wireless and Scan menu items on the left panel.
3. Click the ScanAPs button. A list will appear of competing wireless
networks, including the channels they are using. Write down one or
more of the lesser-used channel numbers, since a less used channel
should be better for your MG8702 device.
4. On the left panel, click the Wireless Basic menu item.
5. On the Basic page, select the channel you want in the Channel
pulldown, then click Save.
