Unless there is a reason you need an RHEL 5, for example a proprietary application that won't run on a new version, you should upgrade to RHEL 6. It is running a much more recent kernel, 2.6.32 I believe, it should have the driver included for your Atheros NIC included and it will work out of the box.
Though, if you are an average desktop user, RHEL might not be very well suited for you in the first place, Fedora is more aimed towards desktop users because it is more current.
