The Network Manager Applet Icon

Network Manager is the application that, since Fedora 11, the GNOME Desktop uses to handle a wide variety of network devices and connections, that allows you to access the Internet. Network Manager is used to configure all your network connections from wired to wireless network, mobile broadband to xDSL network and VPN, too. And if you don't know about DNS, DHCP or pppoe, Network Manager does it all for you. If you use your computer at home, and have an xDSL connection, it is already up, you dont need to configure anything. With a wireless or broadband connection, the steps needed to setup them are simple and easy to do, just a fiew clicks and fill in your personal informations.

In Fedora 13, once inserted your card, you can easily create a Mobile Broadband connection, as indicated below.

In this way, you are able to know when the device has a signal and if it is roaming or not.
Network Manager in Fedora 13, uses the gnome-bluetooth plugin to help to configure your Mobile Broadband with the service provider.
If you have a Bluetooth adapter and a mobile phone (GPRS) that supports Bluetooth DUN,

NM state:                 connected
NM wireless hardware:     enabled
NM wireless:              enabled
NM WWAN hardware:         enabled
NM WWAN:                  enabled

Other Networking Tools

In Fedora 13, Network Manager is the default GUI of the GNOME Desktop, handling the network devices and connections. Though there is another tool, (system-config-network or System -> Administration -> Network) used to network setup. Probably in next releases of Fedora it will be removed. As seen, Network Manager is cool!

To Access a Remote Server

In Fedora 13, the GNOME Desktop has a tool that allows you to access to a Remote Server using its file manager, Nautilus. In the menu-bar select Places -> Connect to Server... Once filled in the necessary connection informations, for quick selection, you can (Add) Bookmark the Server, in Nautilus and in the first section of your Places menu.
