If your network supports \acronym{DHCP}, you may already be set up for online access. To check this, click on the NetworkManager icon. There should be a ``Wired Network'' heading in the menu that is displayed. If ``Auto eth$0$'' appears directly underneath, then your computer is currently connected and probably already set up correctly for \acronym{DHCP}. If ``disconnected'' appears in gray underneath the wired network section, look below to see if an option labeled ``Auto eth$0$'' appears in the list. If so, click on it to attempt to establish a wired connection.

\marginnote{An Internet Protocol (\acronym{IP}) address is a numerical label assigned to devices on a computer network. It is the equivalent of phone numbers for your house and allows your computer to be uniquely identified so you can access the Internet and share files with others.} You should see a window showing details about your connection. If your \acronym{IP} address is displayed as 0.0.0.0 or starts with 169.254, then your computer was not successfully provided with an address through \acronym{DHCP}. If it shows another address, it is most likely that your connection was automatically configured correctly. To test out your Internet connection, you may want to open the \application{Firefox} web browser to try loading a web page. More information on using Firefox can be found later in this chapter.

\marginnote{To access the \window{Connection Information} window, you will need to make sure that networking is enabled. Otherwise this option will be gray and you will not be able to select it through the right-click menu of the NetworkManager applet. To enable networking, right-click on the NetworkManager applet and select \button{Enable Networking} from the popup menu.} If you are still not online after following these steps, you may need to try setting up your Internet configuration manually, using a static \acronym{IP} address.

An \textbf{\acronym{IP} address} is a unique address used for identifying your computer on the Internet. When connecting through \acronym{DHCP} this is likely to change at times. However, if your \acronym{ISP} has provided you with a static address then it will not. An \acronym{IP} address is always given in the form of four numbers separated by decimal points, for example, 192.168.0.2.

The \textbf{network mask} tells your computer how large the network is that it belongs to. It takes the same form as an \acronym{IP} address, but is usually something like 255.255.255.0

The \textbf{gateway} is the \acronym{IP} address at your \acronym{ISP}'s end. It helps your computer connect or ``talk'' with their network, which acts as a ``gateway'' between your computer and the Internet.
