from what I see, xsupplicant doesn't support WPA yet (meaning your WEP 
and WPA-TKIP won't work), but it does support EAP-TLS (certificates). 
I'm not sure what AES is, I don't use that protocol.

I also have FC3, and I can tell you wpa_supplicant works with WPA, but 
not EAP-TLS.  So if I want to use my WPA at home, its wpa_supplicant. 
At work for EAP-TLS, its xsupplicant.  It's ugly, ugly switching between 
these two.
