The rise of the Internet and personal computing has spiked in the past decade, with broadband Internet connections now outnumbering dial-up connections. When making the upgrade to cable Internet service provided by Comcast you will find that, unlike dial-up, a special piece of equipment called a cable modem is required to connect to the Internet. Setting up your new cable modem is a simple task that will have you on-line in no time.
Screw the coaxial cable for your Internet service into the "Cable" port of your new cable modem.
Plug one end of the Ethernet cable into the "Ethernet" port on the new modem and plug the other end into your computer's Ethernet jack or router's "Modem" jack. Substitute a USB cable if your modem has a USB port and your computer has no network card.
Plug your modem's power adapter into the modem, then into a power receptacle.
- If you use a router, unplug your router before connecting to the modem. Connect the modem to the router, wait 30 seconds, and then plug the router in to ensure the devices don't conflict.
