of you want to connect the 655 to another router that has internet services and use the 655 as an access point device, you could connect one of the LAN ports on the Internet router one of the LAN ports on the 655. From there you could still use the DHCP services on the 655 to set up IPs, however I think you'll have to make sure that you set primary and 2ndary DNS addressing to the IP address of the 1st router. So that it will know where to get internet traffic from and pass it along to any connected devices on the 655.
