Internet Explorer is the default browser included with your installation of Windows 98 and acts as an integral part of the Windows operating system to connect your computer to the Internet. Connecting Internet Explorer with Windows 98 to a high-speed modem requires two steps. First, physically connect your computer to a high-speed modem using Ethernet cable. Second, configure the networking software to establish a connection to the Internet.
Plug one end of the Ethernet cable into the "Ethernet" or "Internet" port on the high-speed modem. The cable should fit firmly inside the modem with an audible "click."
Insert the other end of the Ethernet cable into the Ethernet port on your computer. Pull on the cable gently to ensure it is properly seated.
Ensure that high-speed modem power adapter is plugged into an outlet and connected to the correct port on the modem. Green lights on the front of the modem confirm that it is working.
Double-click the blue Internet Explorer icon on the desktop.
Click "Tools" and then click "Internet Options". This opens the networking control panel for Internet Explorer (the default Internet settings for the computer).
Click on the tab labeled "Connections" and then click on the "LAN Settings" button.
Click the check box: "Automatically detect settings" and make sure all other check boxes on this panel are unchecked. Click "OK."
Click "Start," "Shut down" and then select "Restart" to reboot the machine. When the computer boots, open Internet Explorer by clicking "Start," "Programs" and then "Internet Explorer." Type a URL into the address bar to test the Internet connection.
