In order to connect to the Internet with a wired connection, you need to know whether your network supports \gls{DHCP} \emph{(Dynamic Host Configuration Protocol)}. \acronym{DHCP} is a way for your computer to automatically be configured to access your network and/or Internet connection. \acronym{DHCP} is usually automatically configured on your router. This is usually the quickest and easiest way of establishing a connection to the Internet. If you are unsure whether your router is setup to use \acronym{DHCP}, you may wish to contact your \gls{ISP}'s \emph{(Internet Service Provider)} customer service line to check. If your router isn't configured to use \acronym{DHCP} then they will also be able to tell you what configuration settings you need in order to get online.

\marginscreenshot{03-connection-information.png}{ss:connection-information}{This window displays your \acronym{IP} address and other connection information.} If your network supports \acronym{DHCP} then 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. If ``Wired connection 1'' appears directly underneath, then your machine is currently connected and probably setup for \acronym{DHCP}. If ``Disconnected'' appears in gray underneath the wired network section, look below to see if an option labeled ``Wired connection 1'' appears in the list. If so, click on it to attempt to establish a wired connection.

\marginnote{An \acronym{IP} (Internet Protocol) address is a unique number assigned to your machine so that your router can identify you on the network. Think of it like a phone number for your computer. Having this unique address allows the router to speak to your computer, and therefore send/receive data. If you are still not online after following these steps, you may need to try setting up your network connection manually using a static \acronym{IP} address.} To check if you are online, click on the NetworkManager icon in the top panel and select the Connection Information option. You should see a window showing details of 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 assigned connection information through \acronym{DHCP}. If it shows another address (\eg, 192.168.219.133), then it is likely that your \acronym{DHCP} connection to the router was successful. To test your Internet connection, you may want to open the Firefox web browser to try loading a web page. More information on using Firefox can be found later in this chapter.
