I think in WPA the encryption done by WEP is replaced with TKIP which is an enhanced version of WEP with a per-packet key mixing function. Though in some texts it says that TKIP wraps WEP, so...
But my point was actually that if just one of your access points is running on WEP then you are not really WPA protected. Even if the others run WPA.
