by Maya Austen

Get your new computer up and running with your Comcast Internet service in no time. The steps you need to take to accomplish this task varies depending upon your goal. When the goal is to replace an old computer that was formally connected directly to your Comcast modem, one procedure is followed. If the goal is to add a new computer to your wireless home network with Comcast Internet service, another procedure must be followed. In any case, you will be surfing the Web courtesy of Comcast very soon.

Connect the New Computer to the Comcast Modem or Gateway

1

Shut down the computer.

2

Plug the coaxial cable, which is connected to the cable wall outlet installed by the Comcast technician, into the modem or gateway's "Cable" terminal. Secure the cable's connection to the terminal by twisting the screw-on connector, which encases the cable's plug, clockwise until finger-tight.

3

Connect the modem or gateway device to a power source and turn it on.

4

Insert one end of an Ethernet cable into the modem or gateway's Ethernet port. Insert the other end of the Ethernet cable into the Ethernet port on the computer.

5

Launch the computer's Web browser. Follow the on-screen instructions to download the Comcast installation software onto your computer.

6

Log in to the computer using an administrator account. Open the Comcast installation program. Follow the on-screen instructions to complete the Comcast installation set up for your computer.
