network-manager-gnome | network management framework (GNOME frontend) | Mehr ...
NetworkManager attempts to keep an active network connection available at all times. It is intended only for the desktop use-case, and is not intended for usage on servers. The point of NetworkManager is to make networking configuration and setup as painless and automatic as possible. If using DHCP, NetworkManager is _intended_ to replace default routes, obtain IP addresses from a DHCP server, and change nameservers whenever it sees fit. . 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 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.
