I am being driven crazy, my D-LINK modem does not like my Airport extreme, I have a d-link modem connected to my Airport extreme and the WDS to a Express to extend our network. I keep getting DHCP problems and I keep getting the double NAT messages. The DHCP Server settings on my d-link modem is as follows... and I dont know what to put my Airport extreme settings as. Im not sure if I am meant to put them as the same as my d-links but every time I try I get "The DHCP range you have entered conflicts with the WAN IP address of your base station". If I turn off my d-link modem and turn it back on it works for a few hours and then screws up again. o.0 I have had weeks of problems.
