If your system tray does not show any network connection icon, the applet is probably
not started. Press [Alt] + [F2] and enter nm-applet to start it manually.
5.5.1 Connecting to Wired Networks
If your computer is connected to an existing network with a network cable, use the
NetworkManager applet to choose the network connection.
1 Left-click the applet icon to show a menu with available networks. The currently
used connection is selected in the menu.
2 To switch to another network, choose it from the list.
3 To switch o all network connections, both wired and wireless, right-click the
applet icon and uncheck Enable Networking.
5.5.2 Connecting to Wireless Networks
Available visible wireless networks are listed in the GNOME NetworkManager applet
menu under Wireless Networks. The signal strength of each network is also shown
in the menu. Encrypted wireless networks are marked with a shield icon.
Procedure 5.3 Connecting to a Wireless Network
1 To connect to a wireless network, left-click the applet icon and choose an
entry from the list of available wireless networks.
2 If the network is encrypted, a dialog opens. It shows the type of encryption
the network uses (Wireless Security) and holds a number of input elds ac-
cording to the respective encryption and authentication settings. Enter the
appropriate credentials.
3 To connect to a network that does not broadcast its service set identier
((E)SSID) and therefore cannot be detected automatically, left-click the Net-
workManager icon and choose Connect to Hidden Wireless Network.
4 In the dialog that opens, enter the ESSID and set encryption parameters on
the Wireless Security tab if necessary.
5 To disable wireless networking, right-click the applet icon and uncheck Enable
Wireless. This can be useful if you are on a plane or in any other environment
where wireless networking is not allowed.
A wireless network that has been chosen explicitly will remain connected as long as
possible. If a network cable is plugged in during that time, any connections that have
been set to Connect Automatically will be connected, while the wireless connection
remains up.
