Wireless problems F8T3

When I plug my USB wireless adapter into my computer I get an selinux 
warning.  I've pasted them below.  Also the contents of 
/var/log/messages as they pertain to the connection of the wireless 
adapter.  It appears that I need a driver for the wireless and if 
anybody knows where to get it I would appreciate the link.  I don't 
understand the selinux part of the problem and if somebody could 
enlighten me that would be great.

Thanks,

Summary
    SELinux is preventing /bin/ln (udev_t) "create" to <Unknown> 
(etc_t).

Detailed Description
    SELinux denied access requested by /bin/ln. It is not expected 
that this
    access is required by /bin/ln and this access may signal an 
intrusion
    attempt. It is also possible that the specific version or 
configuration of
    the application is causing it to require additional access.

Allowing Access
    Sometimes labeling problems can cause SELinux denials.  You could 
try to
    restore the default system file context for <Unknown>, restorecon 
-v
    <Unknown> If this does not work, there is currently no automatic 
way to
    allow this access. Instead,  you can generate a local policy 
module to allow
    this access - see http://fedora.redhat.com/docs/selinux-faq-
fc5/#id2961385
    Or you can disable SELinux protection altogether. Disabling 
SELinux
    protection is not recommended. Please file a
    http://bugzilla.redhat.com/bugzilla/enter_bug.cgi against this 
package.
