I can see there is only one modem and router. Your mode will be the main DHCP server I guess. Devices behind the SG1008D switch will get IP addresses automatically from the modem. Devices behind the WR940N router will get IP addresses from the router. If you want the modem to be the only DHCP server, you can set the 940N as access point or with DHCP server disabled.

thank you uutommi!
