I have created a new yum repository for Fedora Core 3 at http://www.marcanoonline.com/downloads/repos/fc3/. It only contains currently the required RPMs for wireless networking using an Atheros chipset based card. A previous post of mine explain how to setup the network for Fedora Core 2 but nothing has changed for this new release. On a few days there will be another programs on this repository, starting with my patched version of positron (the synchronization manager for the Neuros Audio Computer)
