Networkmanager is a system network service that manages your network devices and connections, attempting to keep active network connectivity when available. it manages ethernet, wifi, mobile broadband (wwan), and pppoe devices, and provides vpn integration with a variety of different vpn services.
this package contains a systray applet for gnome's notification area but it also works for other desktop environments which provide a systray like kde or xfce. it displays the available networks and allows users to easily switch between them. for encrypted networks it will prompt the user for the key/passphrase and it can optionally store them in the gnome-keyring.
