wpa and supplicant clarification

[akonstam at trinity.edu]

As I understand it wpa and supplicant are programs that strengthen the
security if wireless communication over that provided by WEP access
passwds.

But what is not clear is this. To use wpa or one of the of the forms
of supplicant it seems to me you would have to have control of the
access point as well as the DHCP server for that access point.

My access point is serviced by AT&T wireless service. I don't see how
I could the change their reliance on WEP authorization.

Am I wrong. If so could someone point me to a document that explains
how to use wpa ot supplicant in this environment?
