It can be about 100 different reasons.

If you provide us with little more data, maybe we can help.

What FW is running on ZD, which ios version. Is it in use or not at the time. Maybe it just goes back to sleep. Is it at the edge of a cell, is it in use when this happenes,...

Did you increase the "Inactivity Timeout" in the advanced options? It should say Terminate idle user session after 5 minutes of inactivity after creating your WLAN. You can change to a Max of 500 minutes. Not sure if it can be disabled in CLI or not.

ThX using >>>>

ZD300 w/ build 15

iOS = 7, OSX (mountain lion), and Windows = 7 << expanded to include windows 7 and OSX (All disassociate at a 5 minute increments.)

"inactivity timeout" set for 480 minutes

No, not on edge of cell.

iOS and OSX in use when a disassociation message is created. Win 7 is sleeping.

This behavior is a result of current iOS software's aggressive power-saving strategy.

Current iOS devices will typically disassociate from their AP shortly after their screen has been deactivated. They will periodically wake up, re-associate, check for pending application-layer notifications, disassociate, and repeat the process. They will re-associate as soon as the screen is activated and will stay associated for the duration of screen activity.

not sure if this can help or not as the scenario is not well defined, but this article here explains a couple of things about the behaviour with iOS 7 + captive portals.

It seems that if a specific hostname, that changes with a round robin scheme, is not reachable, then there is a disconnection / the login page pops up.
