In Fedora, if the drivers come in an rpm package, generally all you have to do with the default setup is install the drivers. Unfortunately, with network cards, this is way easier if you already have a working internet connection, so if you can, connect your computer to the internet (temporarily) with an ethernet cable so you can download the drivers. Once you're connected, here's what to do next:
-Set up yum to work with the repository where the driver you want is (in this case, livna.org - see the links to instructions in my previous post)
-As root, run:
yum install madwifi
yum will download madwifi, anything else it needs to work (probably at least a kernel module), and install it all automatically. If you don't have any way of getting an internet connection from Fedora, you'll have to download the rpm and its dependencies and install them yourself. If that's the case, just say so, and somebody (maybe me) will guide you through it.
-Once the driver is installed, reboot your computer (this is the simplest way)
-Go into System Settings | Network, and look in "Hardware" for something like "Atheros (...)". If you've got the same version of the card as me, that's your card right there, and you can switch back to the "Devices" tab and hit new, and choose the obvious choices ("wireless", etc).
If you manage to install the madwifi drivers and reboot without your computer complaining at all about them, and you still don't see anything in the "Hardware" section, you probably have a different version of the card, which means madwifi won't work, and I can't help you much.
