The big question is whether or not NetworkManager is managing the 
network connections:

   ps -ef | grep Network

If it is, then there should be a little NetworkManager GUI applet that 
will control things. I've never used xubuntu, so I'm not sure where to 
tell you to look.

If NetworkManager is NOT running the show, then the file you'll find 
most helpful is /etc/network/interfaces. Its format is described in 
the interfaces(5) man page. Assuming that your wired interface is 
eth0, you'll probably want a couple lines in that file:

   allow-hotplug eth0
   iface eth0 inet dhcp
