I would set the modem/router (which I assume is the source of your DHCP addresses) to only offer addresses within a restricted range, say .101-.249, and then give the Ubuntu box a fixed address outside of that. This is what I have at home, with fixed boxes (servers, ip printers) plus DHCP boxes (various laptops) and it works fine. If you don't have configuration access to the modem/router, then I would try giving the Ubuntu box a fixed address anyway, higher than the default one the laptop is being assigned.
