NetworkManager is the ideal solution for a mobile workstation. With NetworkManager, you do not need to worry about configuring network interfaces and switching between wired or wireless networks when you are moving. NetworkManager can automatically connect to known wireless networks. If you have two or more connection possibilities, it can connect to the faster one. You can also switch between available networks manually and manage your network connection using an applet in the system tray.

10.1. Use Cases for NetworkManager

NetworkManager provides a sophisticated and intuitive user interface which enables users easily to switch their network environment. However, NetworkManager is not a suitable solution in the following cases:

  • You want to use more than one provider for dial-up for one interface.

  • Your computer is a router for your network.

  • Your computer provides network services for other computers in your network, for example, it is a DHCP or DNS server.

  • Your computer is a Xen server or your system is a virtual system inside Xen.

  • You want to use SCPM for network configuration management. To use SCPM and NetworkManager at the same time, disable the network resource in SCPM configuration.

  • You want to use more than one active network connection simultaneously.
