Macintosh and Linux Users:

Configuring TCP/IP Settings

If you are using a Macintosh computer or the Linux operating
system, you must ensure that your computer’s network, or
TCP/IP settings, are configured correctly. Otherwise, you will
not be able to connect to the Internet.
If you are a Windows user, you don’t have to perform this task
because Windows automatically configures your network
settings.
