If you find that the automatic method (DHCP) of connecting to your network doesn??™t work, it gets
a bit trickier to connect to the Internet. Different Linux distributions offer different tools for manually
configuring your Internet connection. The following sections describe a few graphical tools
and some command-line and configuration-file approaches to configuring wired and wireless network
connections.
Configuring Ethernet During Installation
Many Linux install processes ask you if you want to configure your network connection for your
Ethernet cards. This is typically just for your Ethernet cards and not for dial-up modems or other
networking equipment. Information you??™ll need for that process (IP address, gateway, DNS server,
and so on) is explained in Chapter 7.
When you boot Linux, you can check whether you have access to the Internet by opening a Web
browser (such as Firefox or Konqueror) and typing in a Web address. If the Web site doesn??™t appear
in your browser, you??™ll need to do some troubleshooting. The section ???Understanding Your Internet
Connection??? later in this chapter provides information on how to track down problems with your
Internet connection.
