Dial-up Internet is accessed through a telephone line. When you connect through a phone line, it "ties up" that line so that nobody can use that particular phone line. Dial-up was a popular way to surf the web when it was first available to the public, but now most people use high-speed modems and Wi-Fi. Almost all computers have a built-in modem that you can use for dial-up access. You will need a dial-up subscription with an Internet provider before you attempt to get online from home.
Connect a phone cable between your computer and the wall phone jack.
Go to "Start > Control Panel > Network and Internet Connections."
Choose "Create a Connection" or "New Connection Wizard."
Type in your country and area code, and if you need to dial an outside number.
Hit "OK" again on the next screen to confirm the number and location. Hit "OK" when you see the New Connection Wizard.
Choose "Connect to the Internet" when it asks you what you want to do. Hit "OK" to continue.
Choose "Set up my connection manually" and hit "OK."
Choose "Connect using a dial-up modem" and hit "Next."
Type in the name of your ISP (Internet Service Provider) and hit "Next."
Type in the telephone number you are going to use to access the Internet and hit "Next."
Type in the username and password that you set up through your ISP when you first purchased a subscription plan. Hit "Next" to continue. Hit "Finish" to allow the setup to complete itself.
