We have several iPad devices operating in Kiosk mode, or guided access, connecting to a WPA2/PSK WLAN. These devices are configured to not go to sleep. We have the user idle timeout configured for 86400 secs on the wlan, and the session timeout disabled. We are seeing issues where these devices will just stop communicating, and will stop responding to an ICMP ping. However, on the controller, they show associated and in the run state, with a good connection. Often from the WLC client view, we see last disassocation reason as Device idle. These devices are on the 5GHZ band and have great connection stats as far as RSSI and SnR. We are on controller code 8.5.135. We adjusted the default user idle timeout from 300 secs to 86400, and this seemed to minimize how often this was occurring. Has anyone experienced this? Any input on this is appreciated.
