So WPS is not necessarily tied to the encryption method.
When installed with the WPA2/WPS IE Update, a Windows XP/SP2 client recognizes the WPS IE in the Beacon or Probe Response frames. Wireless Auto Configuration on the client uses PEAP-TLS to connect to the WISP network as it passes a NULL user name and no certificate to the IAS server. After PEAP-TLS authentication, PEAP-TLV is used to send the URL of the provisioning server to the client. WPS on the client downloads the XML master file and the appropriate sub files. After the guest server permits the client (after payment for instance) and Updates AD with the uname/pw, Wireless Auto Configuration on the client disassociates from the AP, reassociates, and then attempts authentication using PEAP-MSCHAPv2 using valid user/password; IAS server authenticates and authorizes the connection request against the new account in AD. In this example, RADIUS is quite involved. -Emerson -----Original Message----- From: Michael Griego [mailto:[EMAIL PROTECTED] Sent: Tue 7/11/2006 2:02 PM To: [email protected] Subject: Re: [WIRELESS-LAN] SSIDs: broadcast and non-broadcast If I had to make an educated guess, I'd say yes. Since the WPS IE is something that the AP would have to determine and broadcast in management frames, I'd say that the two (IE and RADIUS pieces) are related but not reliant on each other. --Mike On Jul 11, 2006, at 12:33 PM, Frank Bulk wrote: > Mike: > > Ah, now I see what you're talking about! > > They are related, but not the same.
