Once you have all of the equipment, you'll need to set up your modem and Internet connection. If your modem wasn't set up for you by your Internet service provider (ISP), follow the instructions that came with your modem to connect it to your computer and the Internet. If you're using Digital Subscriber Line (DSL), connect your modem to a phone jack. If you are using cable, connect your modem to a cable jack. For more information, see Set up a broadband (DSL or cable) connection.
