I think you need to look at bridging your laptop's ethernet NIC and
wireless NIC. You will need the bridgeutils (not sure of Ubuntu's
package name). You basically will need to create a bridge then add the
two NIC's to it. That way your Debian PC will think it's directly
connected to your network and can use DHCP etc. Don't forget to add
your Debian desktop PC's MAC address to the wireless router if it has
MAC authorisation.
