Last Month the Japanese try to retrive this mod a little bit more. They played in the at 2pm CET. At the moment the gametracker,com Server Monitorring is off. Hope soon they turn it on. The ranking seems to work.
Upnp better be on, I have never tried without media server, but mine seems to work full speed with it active. I can however say this, the wireless on this box is mostly for show. Tragic transfer speeds, mine is 6 meters away from the router and it was just unbearable. Cable if you can
