While these drivers are not included (yet), they can be found at http://rt2x00.serialmonkey.com/wiki/index.php/Main_Page
I have had no success with any other drivers for this chipset. They have all failed at compile time. This driver works great (I grabbed the CVS tarball, but the normal verion should work too).
Unpack the drivers and cd to it
run these commands
2) su -c "make install"
3) su -c "make install-fedora"
You should be able to use the drivers right away (no reboot or modprobing). Check to see if it was found in your favourite network configuration tool. The device node should be /dev/wlan0.
