As a Fedora user, I'm confused by what kind of networking your having a problem with. I have a cable modem connection to the internet, I have a router connected to the modem, I have ethernet cables attaching my boxes to the router, when I install Fedora 11 onto a new box that is connected to the router, Fedora automatically attaches to the network.
There is a Network Connections app under System-->Preferences that allows you to set up other different connections like Wireless, Mobile Broadband etc., but, except for tethering my cell phone to my laptop, I've never had to do any configuration to set up a basic network.
BTW: Fedora comes with SELinux and Firewall enabled. You must disable them if you want the network to set up automagically.
If you need a link, here's one that I refer back to occasionally:
It's set to point at the network section.
