Introduction
The Motorola Model MT7711 is a 24x8 DOCSIS 3.0 cable modem with a
built-in AC1900 WiFi router plus 2 telephone jacks that has 4 Gigabit Ethernet
ports. This model connects to Comcast Xfinity's cable Internet service with
Voice. Model MT7711 can provide shared Internet access to
Ethernet-capable and WiFi devices including computers, smartphones,
tablets, HDTVs, game consoles, security cameras, and streaming media
devices. The MT7711 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 MT7711 are in the Quick Start that
comes with Model MT7711 and that is duplicated in Chapter 2 of this User
Guide.
Model MT7711 has a Configuration Manager that provides a lot of technical
information about Model MT7711 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
If you don’t have cable Internet service, please order that from your cable
service provider. Comcast Xfinity customers should also order phone service
if they want to use the MT7711 phone lines. This phone capability works for
Xfinity, but not for most other cable services since they use a different
version of PacketCable to deliver their phone service.
Now connect your MT7711 as shown on the following page.
Connecting to a Coax Cable
Please see the connection photo on the next panel. You connect
your MT7711 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 MT7711 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.

11
ON/OFF button
POWER
Connect the supplied power
supply between the power jack
and an electrical outlet.
PHONE (TEL 1-2) If you have Xfinity
phone service, you can connect
telephones to either or both of
these phone jacks.
ETHERNET (LAN 1-4)
You can connect a computer,
HDTV, game station, or other
Ethernet-capable device to any of
these 4 LAN ports.
RESET
WPS button
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.)

12
Prepare to activate
By now you should have:
•Subscribed to cable Internet service, and possibly to Xfinity phone service.
•Connected your MT7711.
•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 green online
connection light to stop flashing and remain solidly lit. This may take
up to 15 minutes.
You may need your cable service account number for product registration. A
recent cable bill/statement will have this information.
If you’re asked for information about the MT7711, such as the Mac Address
or Serial Number, you can find this on the label on the bottom of the
modem/router.
Activate
Activate your MT7711 by opening the Web browser of a computer or other
device that’s connected to your MT7711, and enter xfinity.com/activate.
Your device can be connected either wirelessly or via one of the MT7711’s
Ethernet ports. If you connect wirelessly, you’ll need the unique Wireless
Network Name and Password printed on the bottom of your MT7711. You’ll
use these in setting up your wireless device to connect to the MT7711. Once
you’ve connected, you can open the browser of that wireless device.
Alternatively, call the
Comcast Xfinity number: 1-800-XFINITY

13
Once your MT7711 is activated either online or by phone, your
service provider will provision your MT7711 service. Typically this
takes less than 5 minutes for Internet, but in some cases this may
take 30 minutes or longer. If you activate voice service for the first
time, your service provider may take several days to activate that
service.
Once you have been activated, try to browse the Web using a device
connected via Ethernet or WiFi to the MT7711. (See the section Wireless
Router below for information on connecting via WiFi). If browsing works,
Congratulations! Your MT7711’s Internet capability is working.
If you have Xfinity phone service and want to use that, make sure the
MT7711’s Tel1 light is ON. (You may have to wait a few minutes after
power-up.) Then plug a phone into the Tel1 port. Take the phone off-hook,
and confirm there is a dial tone. Then make a call, and ask the person who
answers to call you right back. Hang up so you can receive the incoming call
and verify that your phone is working.
For more information about using the MT7711 telephone capability, please
see the Telephone Adapter section. If your MT7711 is NOT working, see
Troubleshooting Tips.

14
Configuration Manager
You may not need to use the MT7711’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 MT7711.
•You want to set up special Internet gaming settings.
•You want to get performance information about the MT7711 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 MT7711 Configuration Manager, open your Web
browser. Type http://192.168.0.1 in the address bar and then 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.

15
Wireless Router
As noted before, the MT7711 has a unique Wireless Network Name/SSID
and Wireless Security Key/Password printed on the MT7711’s bottom label.
Set up your wireless devices to work with this SSID and security key, or with
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 MT7711 in a central place so that it’s not too far
away from your wireless devices that need Internet access.
•Try to avoid interference from Bluetooth headsets and stereos, microwave
ovens, WiFi-capable printers, and 2.4 GHz cordless phones and base
stations. Try not to put the MT7711 close to these interfering devices.
•Sometimes it helps to change the MT7711 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. Sometimes devices with a
weak wireless signal will connect to the MT7711, and often those devices can
slow down your network’s WiFi. If you need greater wireless range far away
from your MT7711, 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

16
Telephone Adapter
The MT7711 includes two telephone ports that support standard (land line)
telephones and other devices. The MT7711 is designed to work with
Comcast Xfinity voice service only.
To use the telephone ports, first make sure you have subscribed to Xfinity
voice service. This service may be provisioned to support either one line on
Tel1, or two phone lines, on both Tel1 and Tel 2, with two different phone
numbers.
You can connect almost any standard telephone equipment into an
activated MT7711 telephone port. This includes almost anything that
connects using an RJ11 phone plug — telephones, cordless phone base
stations, answering machines, etc. (If you want to connect a security system,
check with the security system manufacturer for compatibility.)
Additional details can be found in the Telephone Adapter chapter.
The Battery Purchase or Replacement section describes how you can
make sure you have phone service even if your MT7711 loses power.

the Tel1 light may blink continuously.
The Tel2 LED will only light if Tel2 is provisioned for a second phone
line.

19
Battery Purchase or Replacement
The MT7711 has battery back-up circuitry which is for Telephone (Tel1)
back-up only. The MT7711 typically does not ship with a battery included. A
battery is not required for normal operation with AC power. If you lose AC
power, a back-up battery allows the telephone plugged into Tel1 to still
function.
If you want a back-up battery, you can purchase one separately online. The
battery is Model 98250 from MTRLC LLC. (If you ever need to check that
you have the right battery, look on the battery label for BP-15033-22/2150
S.)
If you have the right battery installed and power is lost, the Tel1 jack will
provide up to five hours of talk time or eight hours of stand-by time. The
Tel2 jack does not provide this back-up feature. Only phones that do not
require their own power source will work during a power outage (unless the
phones are provided with their own separate battery back-up system). It’s a
good idea to have at least one phone handy that just needs to plug into the
MT7711, and not into a power jack.
Another way to handle loss of AC power is to plug the MT7711 into an
Uninterruptible Power Supply (UPS). In that case the amount of talk time and
stand-by time depends on what UPS you choose.

Telephone Adapter
The MT7711 includes two telephone ports that support standard (land line)
telephones and other devices. The MT7711 is designed to work with
Comcast Xfinity voice service only.
To use the telephone ports, first make sure you have subscribed to Xfinity
voice service. This service may be provisioned to support either one phone
line on Tel1, or two phone lineson both Tel1 and Tel2, with two different
phone numbers.
You can connect almost any standard telephone equipment to an MT7711
telephone port. This includes almost anything that connects using an RJ11
phone plug—telephones, cordless phone base stations, answering
machines, etc. (If you want to connect a security system, check with the
security system manufacturer for compatibility).
You can connect individual devices, or you can connect multiple devices that
plug into the same phone line. (Their Ringer Equivalence Numbers need to
add up to 5 or less.) One way to connect multiple devices is to plug the
MT7711 phone port into a jack connected to existing telephone wiring.
Before doing this, make sure to disconnect the wiring totally from the
telephone company’s network demarc. This is normally done by unplugging
a phone cord at the jack nearest to where the phone line comes into your
home. After you unplug that phone cord, check that none of the phones
on that line gets dial tone when you go off-hook. If they don’t get dial
tone, it’s safe to connect a phone cord from one of the line’s jacks to an
MT7711 phone jack. After you do that and power up the MT7711, all the
phones on that line should get dial tone.
You may want to attach a cordless phone base station to the MT7711, and
then place cordless handsets wherever you like. The Battery Purchase or
Replacement section describes how you can make sure you have phone
service even if your MT7711 loses power.
