I am expieriencing some authentication issues with our users who are being migrated to Windows 7. I currently am running 6.0.182 on our 4404 controllers with 1242 APs. I am also running 2 ACS 1113 Radius servers along with a server running ACS 4.1 configured with the Remote Agent for the 2 ACS appliances. I am running WPA2 encryption with EAP-FAST authentication.I have adjusted the EAP timeout on the controllers to 30 seconds. I can switch the authentication method to LEAP and that works most of the time. If that doesn't work then a reboot of the AP will generally fix the issue for a short time.
Most clients are using Dell E6400 laptops with Broadcom wireless NICs. The laptops are running the latest drivers for Windows 7 and are configured correctly. Some clients get on fine and other absolutely will not connect. They are repeatedly prompted about accepting the PAC file and will not connect. Eventually the systems assigns itself the generic 169.254.x.x address.
Is anyone having similar issues with EAP-FAST and Windows 7?
