This is a known issue. 

Reboot the AP and it should all be good.

You could be hitting this bug:

You can identify the issue if you open a Wireshark on the client side and filter DHCP packets. If you see many DHCP discoveries and no DHCP Offer until 3 minutes, then you're done.

If so, move to latest code 8.10.151
