Lost ip addresses

Using MN-700 as an access point with a D-link router in
front of it as a gateway to the internet. The D-Link is
DCHP enabled and is supplying ip addresses for all
downstream devices, including those connected to the MN-
700. After a random time the wireless attached devices
lose their ip addresses and even after device reboot
cannot retrieve a new address. Any hardwire attached
devices do not have this problem.

Any help out there???
