How to Install a New Modem on a Comcast Internet Cable

Broadband Internet access allows you to download files such as music, video, games or movies at incredibly fast speeds. The two most popular broadband services are known as cable and DSL. Cable, in particular, offers fast speeds without having to be near a central office, and it uses the same hookup cables you would to get your regular cable TV.

Things You'll Need

  • Ethernet cable
  • Comcast cable hook-up


  • Connect the coaxial cable that runs through the wall to the cable modem. Look for a screw-like port for the cable head.

  • Connect the ethernet cable to the cable modem, and then connect the other end of the ethernet cable to the computer.

  • Plug the cable modem into a power outlet. If you have a surge protector, plug it into that instead to avoid power surge issues. Then turn on the modem. Wait for all the indicator lights on the modem to turn on before proceeding.

  • Turn on your computer, and open your Web browser. As Comcast requires no login information for Internet access, this should give you full access to the Internet.
