NetworkManager

NetworkManager provides automatic network detection and configuration for the system. Once enabled, the NetworkManager service also monitors the network interfaces, and may automatically switch to the best connection at any given time. Applications that include NetworkManager support may automatically switch between on-line and off-line modes when the system gains or loses network connectivity.

These facilities are most useful for modern laptops, where the user may move between wireless networks, and plug in to a variety of wired networks, but NetworkManager also provides features that are relevant to workstations. Current versions of NetworkManager support modem connections, and certain types of VPN. Development of these features is ongoing.

NetworkManager requires Fedora to have drivers for the wired and wireless interfaces on the computer. Many manufacturers of modems and wireless devices provide limited support for Linux. You may need to install additional drivers or firmware on your Fedora system in order to activate these interfaces.

Drivers first
NetworkManager may only work with network interfaces once the relevant drivers are correctly installed on your system. Reboot your system after installing a new firmware or a new driver in order to ensure that the changes take effect.
