Hi, and welcome to LQ!
As for the FC - it does (like any other Linux installation)
what it's told to do. If you didn't disable networking, and
didn't set a fixed IP if you haven't disabled networking, it
will go and try to get a DHCP lease, which is exactly what
Windows would be doing, too.
I'm not a Fedora-user (or fan, for that matter), but something
along the line of
chkconfig network disable
should solve the problem.
