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 page 3.
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.

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.
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.
This may take up to 15 minutes.
Activate
Activate your MT7711 by opening the Web browser of a
computer or other device that’s connected to your MT7711,
and enter
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
xfinity.com/activate. Your device can be
4
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 MT711 telephone capability, please see the
Telephone Adapter section on page 8. If your MT7711 is NOT
working, see
Troubleshooting Tips on page 12.

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 below.

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 the 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

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, Tel1, or both Tel1 and
Tel2.
You can connect almost any standard telephone equipment
into an activated MT7711 telephone port. This includes almost
anything that connects using an RJ11 jack—telephones,
cordless phone base stations, answering machines, etc. (If you
want to connect an alarm system, check with the
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, it’s safe to
connect a phone cord from one of the line’s jacks to an MT7711
phone jack.
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 on page 11
describes how you can make sure you have phone service
even if your MT7711 loses power.

get high Internet speeds, but your service provider may want to know so
they can adjust their network.
Please note: If no telephone service is provisioned, both the
Tel1 and Tel2 lights will blink continuously. To turn the
blinking off, first plug a phone into one of the phone ports,
then take the phone's handset off-hook, and then put the
handset back on-hook. Now repeat the process for the other
phone port. The Tel1 and Tel2 lights should now be OFF.

Battery Purchase or Replacement
The MT7711 has battery back-up circuitry which is for
Telephone 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 your telephone to still function even when you
lose your Internet connection. If you want a back-up battery,
you can purchase one online.
The type of back-up battery that can be used with this
product is Model 98250 from MTRLC LLC, and is labeled
15033-22/2150 S .
Note that in the case of loss of power, the Tel1 jack will
provide up to five hours of talk time or eight hours of stand-by
time when your MT7711 is equipped with an optional battery.
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 available that just needs to plug
into the MT7711, and not into a power jack.

Troubleshooting Tips
What if I can’t make an Internet connection right after
installation?
• First turn your MT7711 off for at least 8 seconds, then on, to
see if that fixes the problem.
• Check the connections you’ve made to your MT7711. Power
and coax connections are required, and up to 4 Ethernet
connections are optional. Are those connections good? Be
sure that the coax cable connection is finger-tight, possibly
using the coax wrench. Do not over-tighten.
• Check that the MT7711’s power supply is plugged into a live
outlet, and that the Ethernet cable (if used) is connected
securely.
• Make sure that your coax cable is live. If you have cable TV
service you can check that by using it with a TV.
• Check that you provided the correct setup information to your
cable service provider.
• Contact your cable service provider to make sure they’ve
turned on your Internet service.
What if I can’t make or receive phone calls right after
installation?
• Make sure that you’ve ordered Xfinity phone service.
• Make sure that the Tel1 light is ON (lit solidly). It may take
several minutes after power-up before voice service is
established. Note also that it may take several days to activate
voice service for the first time.
• If the Tel1 light never turns on, turn your MT7711 off for at least
8 seconds, then on. Wait up to 10 minutes to see if that fixes
the problem.
• If the Tel1 light still isn’t ON, call your service provider.
• If the Tel1 light is ON but you can’t make and receive calls,
check the connections to your phone. Is the phone cord
connected snugly at both ends?
12
• If your phone has a base that needs to be powered, make sure
it has a secure connection to a live outlet.
• If your phone’s handset uses a battery, make sure this is fully
charged.
• If you have connected to your home’s telephone wiring, make
sure that the home's wiring is disconnected at the demarc
from the telephone company’s network. The demarc is where
the telephone company's network enters into the home and
connects to the home phone wiring.
What if my MT7711 has been working, then stops working?
• First turn your MT7711 off for at least 8 seconds, then on, to
see if that fixes the problem.
• If the MT7711’s lights don’t come on, check that the modem is
getting power from its power cube and that the MT7711’s
power button is on.
• Check your MT7711 Ethernet or telephone cables, if used.
• Check with your service provider. Sometimes there’s a service
outage or some other service issue. Sometimes a service
outage also affects your TV service, so check that.
What if I’m getting Internet service but my speed is
disappointing?
• Be sure you know what speed you’re paying for.
• Check the speed with a computer using a wired Ethernet
connection and plugged into one of the modem’s Ethernet
ports. Use one of the tools found when you search the phrase:
broadband speed test. Make sure your computer's wired
Ethernet LAN port supports gigabit rates (1000BT or GE). You
will need this to achieve service speeds of 100 Mbps or
greater.
• If you get good speed when a computer’s plugged into the
modem, you may have a wireless problem. In that case, please
re-read the wireless router section.
• Some video streaming services get bottlenecked, especially at
busy times like after dinner. See whether you have the speed
13
problem at less busy times or when using another streaming
service.
• Try connecting your MT7711 nearer to where the coaxial cable
comes into your home. This lets you see whether your home’s
cabling is a problem.
• If you’re using a splitter with your MT7711, try the MT7711
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.
What if I'm told that my MT7711 isn't approved by my cable
service provider?
If your Cable Service Provider is Comcast Xfinity, then that's
not true. The MT7711 is specifically listed on the Comcast
Xfinity website as an approved device for Internet and phone
services at
mydeviceinfo.xfinity.com . Other leading cable
service providers have a list of certified cable modems for
each of their Internet speeds. You can check the list for your
service provider. You can also find information about
certifications at
www.motorolanetwork.com/services
What if I am connected wirelessly but my connection
seems slow or keeps dropping?
Please re-read the Wireless Router section above.
What if I don’t know my MT7711’s Wireless Network
Name/SSID or Security Key/Password?
The default values are printed on the bottom label of the
MT7711. Use these unless you changed them. If you changed
them, try to remember where you put the new values. If you
have a device that connects wirelessly to the MT7711, it may
show the Wireless Network Name/SSID and Password. You
can also find this information in the MT7711 Configuration
Manager. Information about using this is in the Configuration
Manager section above.
14
If all else fails, reset the device to factory defaults by holding
the Reset button depressed for 10 seconds. (A paperclip
helps.) You can then use the default values.
What if I think that wireless devices are interfering with my
MT7711 wireless router?
1. Where possible, put the MT7711 as far away as possible
from interfering devices such as Bluetooth transmitters
and neighbors’ WiFi routers.
2. To try to pick a less used wireless channel for your MT7711,
first go in to your MT7711’s Configuration Manager.
• Then, click the Advanced button at the top of the page,
then click the Wireless and Scan/Bridge menu items at
the top of the page.
• Click the ScanWirelessAPs button. A list will appear of
competing wireless networks, including the channels
they are using. Write down one or more of the less used
channel numbers, since a less used channel should be
better for your MT7711.
• On the top of the page, click the Wireless Basic menu
item.
• On the Basic page, select the channel you want in the
Channel pulldown, then click Save.
