How to Connect a Mac Computer to the Internet

To surf the Internet or read your email, you will need to connect your Mac to the Internet. You can connect your Mac to a network that is already online, such as the network at your job. Most people connect their home computers with cable modems and broadband connections. Others use DSL and phone lines.

Instructions

Difficulty: Moderately Easy

Things You’ll Need:

• Coaxial cable (for cable broadband Internet)
• Subscription to broadband Internet service
• Phone filters (for DSL)
• Cable or DSL modem (router)
• Ethernet cable
• Mac computer

Connect the Hardware

1. Sign up for service with an Internet Service Provider, such as your local cable or phone company. It will charge you a monthly fee for this and will probably provide the cable modem (router) or DSL hardware that you need.
2. Connect your cable modem to your coaxial cable jack in your home or connect your DSL to your phone line. If you are using DSL, attach filters to every phone that is on a jack. These would have been provided with your modem by your ISP.
3. Connect the modem to the Ethernet port on your Mac using an Ethernet cable. Then turn on the modem if it isn't already on.
4. Click the Apple Menu and choose "System Preferences" and then "Network." Under "Show," choose "Built In Ethernet" from the drop-down box.
5. Click the "TCP/IP" tab and under "Configure IPV4" choose "DHCP."
6. Click "Apply Now" at the bottom of the dialog box. This is usually all you have to do to get connected to the Internet on a Mac.

Tips & Warnings

• In addition to the physical hardware connection, some ISPs also provide software. This will walk you through the process of setting up your connection. Insert and run the CD, if provided, before you connect your computer and cables.
• There are other ways to get your Mac online at Mac101.com (see Resources below). You can connect it to a network that is already connected to the Internet. You can also set up a wireless Internet connection if you have an AirPort card in your Mac, which enables your computer to connect wirelessly.
• You do not need to have cable TV service to have cable Internet for your Mac.
