The only DHCP server is the Linksys router/firewall, which has a built in switch with ethernet and wifi interfaces. It's really not that convoluted. I have two subnets with one firewall/router(linksys) to the Internet... If it would make any difference, I could disable the DHCP on the laptop and provide only static addresses. My girlfriend won't let me have the server/router in the bedroom where the linksys router is, so I am pretty much stuck right now...
