Access Point - AIR-AP1231G-A-K9 - PCs can connect but Apple Macs Cannot ...

Question

Hello,
This is a sort of follow up to a post I made a few days ago. I made changes to my access points and on Windows computers everything works but on Apple products (Macs, iPads, iPhones) the strangest things happen.
(1). About 90% of the time nothing works in that we get NO connection to the Access Point. In the client association logs we see the Mac Address show up but there is a 0.0.0 address where it seems like the device is trying to get an DHCP lease. After a while, the device gets the IPPA address of 169.X.X.X.
(2) After a extended period of time (an hour or more) the Apple device eventually gets an IP address from the network and then is able to successfully connect to the network. However, the connection is short lived and drops after about 30 minutes to an hour.
Is there a problem with the way Apple products encapsulates their network traffic versus Windows or other products?
Again, this not affect any Windows or Andriod based devices (laptops, phones, etc.) They can connect right away and never drop out.
Below is the configuration file for the AP in question, although this is affecting all of our APs:

For initial configuration you can access AP from the Console port.
Following are the guides you need to look at for configuring you 1600 AP :
Cisco Aironet 1600/2600/3600 Series Access Point Deployment Guide
Getting Started Guide: Cisco Aironet 1600 Series Access Points
Moreover you can check the configuration guide from cisco.com/google, based on the Actual software image your AP is running. Some of the newer IOS for AP you can check here.
