freebsd / dhcp

I'm trying to make a transition from linux to unix, but one of the major hang ups is my networked internet connection.

(1) Cable Internet (Adelphia)
(2) Modem -> Cat5
(3) Cat5 -> D-Link Router
(4) D-Link Router -> Cat5
(5) Cat5 -> D-Link 10/100 Ethernet/USB Adapter

On boot it says it sees the USB port, and the D-Link 10/100 Ethernet/USB Adapter.

Slackware Linux was capable of recognizing the connection using dhcp, but not Freebsd.

During install I chose to allow DHCP.

When I try to ssh in or out of the box, I receive an error that states a path to the connection can not be found.

Is there anything else that I should do?

Check out the freebsd handbook - DHCP.
