Good morning to all, I am coordinating a project for installing a wireless network at the Faculty of Statistics of University of Rome. We have been using freeradius with PEAP and EAP-TTLS enabled. All seems to work fine except for the very long authentication times (about one minutes) we are experiencing when using the default Windows XP supplicant. After doing some searches on the previous discussions, I found the following thread where it is said that such a problem may be due to the way the Windows supplicant handles the EAP negotiation: http://www.mail-archive.com/freeradius-users@lists.freeradius.org/msg30473.h... I performed some further searches and discovered that this delay may be due to the four-way handshake protocol used by the client machine to establish a new connection with the AP. Do someone knows if there exists any tuning in the implementation of this protocol able to reduce the waiting time? Thanks in advance for any help! -- Umberto Ferraro Petrillo PhD Dipartimento di Statistica, Probabilita' e Statistiche Applicate Universita' di Roma -- La Sapienza P.le Aldo Moro, 5 00185 - Rome, Italy phone: +39 06 499 10513 e-mail: Umberto.Ferraro@uniroma1.it
