How did you attempt to hook up so far? Did you try this:
start > control panel > network connections > wireless network setup wizard
Or this on the host computer:
start > control panel . network connections > setup or change your work or home network setup
Run the wizard, choose "This computer connects directly to the internet. The other computers on my network connect to the internet through this computer"
Wait a minute. Upon rereading your original post, I need to know what you are using a router for. Is it a wireless router? If so, then your new computer is not connecting to the internet through the 'host' computer, but rather through the router.
I shall await your answers.
