Hey,
There's a nifty little tool called neat (aka system-config-network) you can use to set up your network settings. I don't use gnome or kde anymore, so I can't tell you exactly where it would be on your menu, but you can open up a terminal and type "neat" or "system-config-network" to ...
While this was a great reply that, I think, explained quite well how to solve your problem, I'd like to point out that useful replies to this type of question are quite rare on this mailing list.
See, fedora-config-list isn't a mailing list about configuring fedora, rather it's a list where people discuss developing configuration tools for fedora. A subtle, but important, difference.
A wonderful place to learn how to install, configure, control, and otherwise use your new operating system is fedora-list. It's full of great people who are just itching to answer that type of question. This list, on the other hand, is read by great people who are busy trying to build the tools you use to configure the OS. They're not quite as interested in (nor as good at) explaining the best way to use it.
