Let’s get started 1 Call 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.
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.
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.
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.

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.
• No matter who your service provider is, check Comcast XFINITY’s Internet Minimum System Recommendations here: https://www.xfinity.com/support/internet/requirementsto-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.
