we have wi-fi setup at work using a zone director, and use guest access, with a hidden SSID, WPA-2 personal, and shared password. It is also setup so that the user must click on a terms and conditions page before using the Wi-Fi. This authentication expires after 8 hours.
Most of our devices have no issues, but most of our iPads seem to have this issue where, once they go to sleep, and the user turns the device on again, they have to re-authenticate every time.
Is there a way to prevent this behavior?
