First, the gritty details:
iPad 2, iOS version 7.1.2
Ruckus ZD 1100 126.96.36.199 build 203
Ruckus ZoneFlex 2942 188.8.131.52 build 203
So, iPad will connect to the WLAN. However, if the screen is locked for about 10 minutes it will become disconnected. I've read other threads about this being an issue with the iPad needing to reauthenticate and to change the grace period, inactivity timer, enable 802.11d, etc. These have all been done with no success.
Also: this issue did not occur before the Ruckus device in place, which leads me to believe it is not an issue with the iPad. However, no other clients are having a similar issue.
