Introduction

The Motorola Model MG8702 is a DOCSIS 3.1 cable modem with a built-

in AC3200 WiFi router that has 4 Gigabit Ethernet ports. This model

connects to standard cable company Internet service. Model MG8702

can provide shared Internet access to Ethernet-capable and WiFi

devices including computers, smartphones, tablets, Smart TVs, game

consoles, security cameras, and streaming media devices. The MG8702

is a dual-band WiFi router, and supports clients that operate on both

the 2.4 and 5 GHz bands.

Basic Installation instructions for Model MG8702 are in the Quick Start

that comes with Model MG8702 and that is duplicated in Chapter 2 of

this User Guide.

Model MG8702 has a Configuration Manager that provides a lot of

technical information about Model MG8702 and that tells you how to

do some useful things as summarized below. Please note that some

users will never need to use the Configuration Manager.

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.
