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.

Connect the supplied
power cube between
the power jack and an
electrical outlet.

If you have Xfinity
phone service, you can
connect telephones to
either or both of these
phone jacks.

You can connect a
computer, HDTV, game
station, or other
Ethernet-capable
device to any of these
4 LAN ports.

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.)

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

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.
