RHELL, thanks for the links.
I had already downloaded the ralink drivers from http://rt2x00.serialmonkey.com/wiki/index.php/Main_Page
but I was unable to find documentation specific to Fedora Core 3 or 4. I checked out the other link that you gave me and the steps listed by that person were very detailed. Unfortunately, these steps were meant for a Mandrake distro and many of the steps didn't apply to Fedora. For example, one of the steps was to locate the kernel source at /usr/src/linux. I don't have this directory. I dont' even know where to locate the kernel source in Fedora Core 4. I'm still very much a beginner.
But if more information is needed from my end, please let me know.
