you need only 1 device to do DHCP serving. so the router will do it here, and the WAP needs to be on the same subnet, so if the router is 192.168.1.1, and the wap needs to have a 192.168.1.x address, and the address of the wap itself would need to be changed, ie, to 192.168.1.2 Turn off the DHCP...
