Sporadic DHCP/connection Issue

Question

Hi, we are having an issue with a number of R600 APs connected through a ZoneDirector 1200. Occasionally
 we will notice connectivity issues with a certain area/AP. Users will 
complain that they are unable to get connected to the wifi network, and 
when we check ZoneDirector we can see that any new client connections to
 the APs are connecting but not obtaining an IP address. This issue only
 ever seems to affect one AP at a time. When we check the Window DHCP 
server we can see there are many IP leases available, and we experience 
no other network issues. After
 disabling the radio on that access point and then re-enabling it, all 
devices that were having issues can immediately connect and obtain and 
IP address, functioning as normal. This leads me to think it is somewhat
 AP related, as the reset of the radio causes everything to function 
again.Has anybody experience similar issues or have any idea for possible solutions?Thanks

Doesn't sound familiar, but I would suggest to run the latest ZD1200 firmware.
