I have prepared a how-to that describes my own efforts getting wpa_supplicant working in F7. I spent a great deal of time going down dark alleys and going nowhere so I am making this available so that others might have an easier time than I did getting wireless working nicely. You may wish to do it differently but my method is at http://www-users.york.ac.uk/~mdc1/fedora_wireless.html If this helps one other person then the time I spent doing this is at least not in vain!
