After having enabled NetworkManager in YaST, configure your network connections
in a dialog available from the GNOME Control Center or from the Personal
Settings in KDE 4. If you use GNOME, start the GNOME Control Center from
the main menu, then select System > Network Configurations to open the
Network Configuration dialog. If you use KDE, start
the Personal Settings from the main menu by clicking
Configure Desktop, then select Advanced > Network Settings to open the Network Settings dialog.

Alternatively, you can start the configuration dialogs from the NetworkManager
applet/widget in the system tray by clicking Configure
(KDE) or by right-clicking the GNOME applet and selecting Edit
Connections.
The GNOME and KDE 4 configuration dialog shows tabs for all types of
network connections, such as wired, wireless, Mobile Broadband, DSL, and
VPN connections. NetworkManager also supports connections to 802.1X protected
networks.
To add a new connection, click the tab for the connection type you want
to use and click Add. Enter a Connection
Name and your connection details and click
OK or Apply. The newly configured
network connection now appears in the list of available networks you get
by left-clicking the NetworkManager applet or widget.
NOTE: Hidden Networks
To connect to a hidden network (a network that does not
broadcast its service) you have to know the Extended Service Set
Identifier (ESSID) of the network because it cannot be detected
automatically. In this case, enter the ESSID and the encryption
parameters, if necessary.
When editing each connection, you can also define if NetworkManager should
automatically use this connection (activate Connect
Automatically) or should use this connection systemwide
(activate System Connection). System
Connections can be shared by all users and are made available
during boot time—before any users log in.
