my hybrid/core is connected complete wireless.
the external connection to my network is an 802.11n draft card and my router is a linksys draft n router.
the MCE internal network is a 802.11g bridge from an ethernet card witha linksys travel router. I have not media directors only an orbitor on the internal network for now, but my fileserver is on the external network. all audio and video comes from it. its a bit bumpy at times, but mostly smooth. I can surf the web etc on the eternal network while streaming dvd ripped movies fine
