Having the same problem on Windows 7, with the same models. Infrastructure: 2 x Cisco Secure ACS servers Cisco 4400 series WLC at each site, SSID is configured with WEP encryption, EAP-FAST Local: Dell laptops (normally Latitude D620/D630s, but some newer) running Windows 7. All are using the Cisco EAP-FAST plugin, installed in automated fashion via MSI. We have made no changes to our infrastructure, and Windows XP clients using the Broadcom Wireless Client for Dell are connecting fine. The clients using the Cisco EAP-FAST plugin connect OK, but often get repeatedly requested to get a new PAC file, sometimes 50-100 times an hour. Is there any workaround for this at all?
