Prepare to activate

By now you should have:

•

Subscribed to cable Internet service.

•

Connected your cable modem.

•

Powered up your cable modem. To do this, the On/Off button

needs to be On. Wait for the online connection light (

) to

stop flashing and remain solidly lit.

This may take up to 15

minutes.

You should have a recent cable bill handy because it has your

account number and you’ll probably need that.

If you’re asked for information about your cable modem, you

can find this on the label on the bottom of the modem.

Activate

For some service providers, you activate by calling them.

Many service providers including Comcast and Cox prefer that

you activate by first opening the Web browser of a computer

that’s plugged into the MB7621’s Ethernet port. Once you’ve

opened the browser, try to go to

www.motorola.com

. This

should bring you to the service provider’s activation page.
