I've got a WLAN that uses WPA2 with PEAP. My MS clients take advantage of Proactive Key Caching to roam from AP to AP without requiring a full 802.1x authentication each time. My Symbol mobile devices, even though they support WPA2, are doing a full authentication as they roam from AP to AP. Is anyone out there using Symbol clients with Cisco WLC's and able to get them to roam without full Radius re-authentication as they roam? If so, what were the tricks?
