Hi,
First, here's out setup:
650 controller, firmware 6.1.3.1
AP-105's
WPA2-PSK AES SSID with tunneling through controller to one LAN subnet
DHCP server is a Windows server
iOS version 6 (not sure if other versions are affected)
The problem:
iPhones and iPads lose connectivity intermittently. Switching Wi-Fi on and off or renewing DHPC lease doesn't help. Rebooting the iOS device fixes the issue but it comes back at some point and another reboot is required. I can see that iOS keeps the IP address from DHCP server so there's some connectivity at least. Laptops are working fine.
I enabled debugging on the controller with this: logging level debug user-debug <mac address>
Here's the output I got when the problem was on and I switched Wi-Fi off and back on on an iPhone (SSID and AP name obfuscated):

I'm new to Aruba so I don't know what that implies, can someone help?
