LET’S GET STARTED
1. Turn o and disconnect any existing modems or routers on your network.
2. Connect a coax cable that has active cable service to the modem’s coax port.
Ensure that you have access to the bottom label during setup and activation
of the modem.
3. Plug the B12 into a power outlet using the supplied power adapter.
4. Wait for the light on the front of the device to stop pulsing and remain solid for
at least 1 minute. This process may take up to 15 minutes and the modem may
reboot multiple times.
ACTIVATE WITH YOUR SERVICE PROVIDER
1. Activate your modem by following your service provider’s activation process.
This process may include using their app or website, or contacting them by phone.
2. Connect your computer or WiFi router to your B12 via the Ethernet port
found on the back of the modem.
3. Confirm that your B12 is connected to the Internet by visiting a website on
your computer or mobile phone. If you cannot access a website, turn your
cable modem o for at least 10 seconds, then on to see if that fixes the
problem. If the problem persists, visit help.motorolanetwork.com.
