A \gls{wireless connection} is when your computer is connected to the Internet via a wireless radio network, also known as Wi-Fi. Laptop computers commonly use Wi-Fi due to their portability, making it easy to access the Internet from different rooms in the house or when traveling. In order to connect to wireless connection, you must have a working wireless network. You will usually need to purchase and install a \emph{wireless router} or \emph{access point}, although some locations will already have a wireless network established.

A \gls{dialup connection} is when your computer uses a \emph{modem} to connect to an Internet service provider through your telephone line.

You can access all the functions of NetworkManager using its icon in the top panel. This icon may look different depending on whether you currently have a working connection, and whether the connection is wired or wireless. If you are unsure, try hovering your mouse over the icon until a short description appears near the cursor. This will read ``Wired network connection `Auto eth$0$' active'' (for example) if you have a working wired connection, or otherwise something else related to networking or connections such as ``No connection'' or ``Networking disabled.''

You can also right-click on the NetworkManager icon. This will open a menu allowing you to enable or disable networking, view technical details about your current connection, or edit all connection settings. In the image above, the check box next to ``Enable Networking'' is currently selected; you can deselect it to disable all network connections. This may be useful if you need to shut off all wireless communication, such as when in an airplane.

If you have an \emph{Ethernet} cable running from a wall socket, a router, or some other device, then you will want to set up a wired network connection in Ubuntu.

\gltodo{``\acronym{DHCP},'' ``\acronym{ISP}''} In order to connect with a wired connection, you need to know whether your network connection supports \gls{DHCP}. This stands for ``Dynamic Host Configuration Protocol,'' and is a way for computers on your network to automatically receive configuration information from your Internet service provider (\gls{ISP}). This is usually the quickest and easiest way of establishing a connection between your computer and your \acronym{ISP} in order to access the Internet, although some \acronym{ISP}s may provide what is called a \emph{static address} instead. If you are unsure whether your \acronym{ISP} supports \acronym{DHCP}, you may wish to contact their customer service line to check. They will also be able to provide you with information on your static address if one has been allocated to you (in many cases \acronym{ISP}s only allocate static addresses to customers upon request).

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 wireless 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.}

368.

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.}
