NetworkManager

537.

In order to connect to the Internet using Ubuntu, you need to use the \application{NetworkManager} utility. \application{NetworkManager} allows you to turn network connections on or off, manage wired and wireless networks, and make other network connections, such as dialup, mobile broadband, and \acronym{VPN}s.

The network connection states: (a) disconnected, (b) wired, and (c) wireless.

You can access \application{NetworkManager} by using its icon found in the top panel. This icon may look different depending on your current connection state. Clicking this icon will reveal a list of available network connections. The current connection (if any) will have the word ``disconnect'' underneath it. You can click on ``disconnect'' to manually disconnect from that network.

This menu also allows you to view technical details about your current connection or edit all connection settings. \marginscreenshot{03-active-connection.png}{ss:active-connection}{Here you can see the currently active connection is ``Wired connection 1.''} In the image to the right, you will see a check mark next to ``Enable Networking.'' Deselect ``Enable Networking'' to disable all network connections. Select ``Enable Networking'' to enable networking again. This can be very useful when you are required to turn off all wireless communications, like in an airplane.

If you are already online at this point as indicated by the NetworkManager icon in the top panel showing a connection, then you may have successfully connected during the Ubuntu setup process. You can also simply open a browser and see if you have access to the Internet. If so, you do not need to do anything for the rest of this section. If not, then continue reading.
