Let’s get started

1Call your cable service provider to order cable Internet

service if you don’t already have it. Mention that your

MB8611 supports DOCSIS 3.1, the fastest cable modem

service standard. Your MB8611 also supports all speeds of

any DOCSIS 3.0 services.

Or, if you already have cable service, 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.

2 Now connect your MB8611 as shown on the next panel.

Connecting to a coax cable

See the connection photo on the next panel. Connect

your MB8611 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 MB8611 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.

RESET button

ETHERNET (LAN)

You can connect a WiFi router,

computer, HDTV, game station,

or other Ethernet-capable

device. To connect your router,

see

If you want to connect a

router

, below.

COAX

Connect a “live” coax

cable 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. 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 that’s plugged

into the MB8611’s Ethernet port.

If you have a computer, plug it into the MB8611’s Ethernet

port. Once you've opened the computer’s 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 normally activate by

calling your service provider.

Another option is to first connect a WiFi router to the MB8611

as described on page 7 of this Quick Start. Then use the

browser of your smartphone, tablet, or other WiFi device to

go to your service provider’s web page, where you should

see an activation page’s onscreen instructions.

For Comcast XFINITY Users Only:

If the activation page does not appear, please go to

www.xfinity.com/activate for more information and to

activate your modem.

Here is a list of phone numbers for some major cable service

providers. (Note that this list is subject to change.)

Comcast Xfinity

1 (800) 934-6489

Cox

1 (877) 206-4210

Bright House (Spectrum)

1 (855) 222-0102

Sparklight (Cable One)

1 (877) 692-2253

Charter Spectrum

1 (855) 757-7328

MediaCom

RCN

1 (844) 987

1 (800) 746-4726

Altice Suddenlink

1 (877) 794-2724

Time Warner (Spectrum)

WOW!

1 (855) 707

-7328

1 (800) 343-2076

Once your MB8611 is activated either online or by phone, your

service provider will provision your MB8611 service. Typically

this takes less than 5 minutes, but in some cases this may

take 30 minutes or longer to complete.

Once you have activated, you should have Internet access for

whatever’s plugged into your cable modem.

Congratulations!

If your cable modem is NOT working, see Troubleshooting

Tips below.

Note: You can connect this device to a WiFi router,

computer, Internet capable TV, game station, or other

Ethernet-capable device.

This product does not include

a router, WiFi, or telephone capability.

If you want to connect a router

Most users will connect a WiFi router to the MB8611. This

connection may be made initially, before activating the

cable modem, or it may be done after the cable modem

has been activated. A wireless router lets multiple devices

(computers, smartphones, tablets, video devices, game

stations…) share your cable modem’s Internet connection,

either wirelessly or through a direct Ethernet connection.

The MB8611 has a 2.5 Gbps Ethernet LAN port for

connecting a router. This is unusually fast and flexible, and

it supports router WAN port speeds from 100 Mbps to 2.5

Gbps.

1. The cable modem and the router should both be

powered off.

2. Plug one end of the cable modem’s Ethernet cable into

the Ethernet jack of your modem and plug the other

end of the cable into the router’s WAN port. (You may

need to disconnect the cable from your computer

first.)

3. Power-up the cable modem. Wait for the ONLINE light

( or ) to be solidly lit.

4. Power-up the router. Wait for the router to complete

its power-up sequence.

5. The Ethernet port light on your modem should be

lit to show the Ethernet connection to your router.

Note the color will be white for 100BT, green for 1 Gig

Ethernet, and blue for 2.5Gig Ethernet.

6. Follow your router’s instructions for setting up the

router and connected devices.

If you haven’t already activated your Internet service, do

that now. (See Prepare to activate on page 5.) Using a

computer or other device connected to the router, try

connecting to the Internet. If it works, Congratulations!

Installation is complete.

Troubleshooting Tips

What if I can’t make an Internet connection right after

installation?

•First turn your cable modem off for at least 8 seconds, then

on, to see if that fixes the problem.

•Check the connections you’ve made to your cable modem –

power, Ethernet, and coax. Are those connections good?

•Check that the modem’s power cube is plugged into a live

outlet, and that the Ethernet cable is connected securely.

•Make sure that your coax cable is live. 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 my cable modem has been working, and then stops

working?

•First turn your cable modem off for at least 8 seconds, then

on, to see if that fixes the problem.

•If the modem’s lights don’t come on, check that the modem

is getting power from its power cube and that the modem’s

power button is on.

•Check your cable modem cables.

•Check with your service provider. Sometimes there’s a

service outage or some other service issue.

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 plugged into the modem.

Use one of the tools found when you search the phrase:

broadband speed test.

•No matter who your service provider is, check Comcast

XFINITY’s Internet Minimum System Recommendations here:

https://www.xfinity.com/support/internet/requirements-

to-run-xfinity-internet-service/

•If you get good speed when a computer is plugged into the

modem, you may have a router problem.

•Some video streaming services get bottlenecked, especially

at busy times like after dinner. See whether you have the

speed problem at less busy times.

•Try connecting your cable modem 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 cable modem, try the cable

modem 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 1000 MHz.

•To take full advantage of the 2.5GE Ethernet port on your

MB8611, make sure the computer or router you connect to

also supports 2.5GE. Your MB8611’s 2.5GE port will also

connect to lower speed 1000BT or 1GE Ethernet ports. See

www.motorolanetwork.com/31

What if I'm told that my cable modem isn't approved for

my cable modem service?

That’s probably not true. Leading cable service providers

have a list of certified cable modems, and you can check the

list for your service provider. You can also find information

about certifications at www.motorolanetwork.com/services
