I have a Intel iMAC 2.4GHz. I know it has build in Airport Extreme. I also have a Airport Express 802.11n. I am having some difficulty making it do what I want. I am wondering if it is even possible. This is my setup: DSL modem -> iMAC in office connected via ethernet. Airport Express -> Airtunes, USB printer, Dish Network DVR connected to Ethernet in living room. My question is can I share my DSL connection from my iMAC to the Airport Express then to my DVR (wired) and even my Wii (wireless)? Thanks in advance for any input.
