Mac OS 9: How to Connect to the Internet via Cable, DSL, or Local Area Network (LAN)

To connect to the Internet via a cable modem, digital subscriber line (DSL), or an Ethernet local area network (LAN), set up your TCP/IP control panel for the "Built-in Ethernet" port. You may use the Internet Setup Assistant, if preferred.

Gather information

Before you begin, gather this information from your ISP or network administrator:
  • domain name server (DNS) addresses
  • whether you should choose DHCP or manual IP address configuration, (used in Step 3 below).

For manual configuration only:
  • IP address
  • router address
  • subnet mask

    1. It is possible that your ISP or local network does not provide DNS addresses, but rather has a method for providing this automatically.

    2. Once you have this information, you may stop here and use the Internet Setup Assistant, or you may continue with the steps below to configure manually, using the TCP/IP control panel. The location of the Internet Setup Assistant on your hard disk differs slightly between versions of Mac OS 9, so you may use Sherlock to find it.

Steps to connect

Follow these steps for manual configuration:
    1. Open the TCP/IP control panel.
    2. Choose Built-in Ethernet from the Connect Via pop-up menu.
    3. From the Configure pop-up menu, choose either DHCP or Manually, as instructed by your ISP or network administrator.
    4. Type the other information you gathered into the corresponding fields. Unless your ISP instructs you otherwise, you may ignore the DHCP Client ID field and the Search Domains field.
    5. Close the TCP/IP control panel.
    6. Click Save when prompted.
    7. Open a Web browser or other TCP/IP application to test your connection to the Internet.
