Wireless Devices with Local Host IP Address as DNS address and Losing Connections

I have a site that uses a Cisco Wireless Lan Controller.  We have 3 access points that attach to the controller.  The controller is not set up as the DHCP and all the access points have static IP's.  About a month ago, the wireless devices were dropping their connection and no one seem to understand why.  Once the connection was dropped, the user could connect wired and get back on and then I would put a static IP into the wireless adapter and the computer worked fine.  I noticed every time I made this change, I would get the standard message that there were multiple networks connected.  I later discovered that the WLC was also sending out IP's.  I turned that feature off and the devices now connect to the correct DHCP server which is set up on the router.  I am still having the issue with devices dropping connections and I noticed that the DNS IP address is set to 127.0.0.1.  I have no idea why that is being changed.  I have checked my router and that is fine.  I have checked my WLC and everything appears to be fine.  No one has access to this device but me and I don't see any setting that would cause this.  Any thoughts?
