I able able to successfully install the drivers for my OEL 6.
It is very simple.
Download a stable release (I downloaded compat-wireless-3.5.1-1.tar.bz2) from the following website to your desktop:
tar xvf compat-wireless-3.5.1-1.tar.bz2
I got the below links from google. Although these are for ubuntu. But, works fine in OEL 6 platform also
You can install software this way, but it won't be managed by yum or rpm. This can be a disadvantage if you later decide to upgrade the system or install other software that may cause a software or dependency conflict.
The Elrepo project provides a lot of additional hardware drivers and related software for RHEL based systems, check http://elrepo.org/tiki/tiki-index.php. You may have to test if a particular software works with the Oracle UEK kernel, but it might be worth a try. You can install the repository configuration file and then use yum to install software as usual.
Or fetch and install the package directly, for instance:
yum install http://elrepo.reloumirrors.net/elrepo/el6/x86_64/RPMS/kmod-compat-wireless-3.3-2.n.el6.elrepo.x86_64.rpm
