WPA requires cipher suite negotiation as part of the association and
just setting the SSID with iwconfig will not allow the driver to
complete association.

You will need an addition program, e.g., wpa_supplicant, when using WPA.

You should be able to use either wpa_supplicant or Xsupplicant for this
(i.e., only one of them is needed, not both).
