No, I can not ftp to xbox when game is playing. I did a continues ping while my xbox is on the dash board when ping still response bur as soon as I start the game, ping dies.
If I go to ms dashboard, ping also dies. If I go the network setting then choose "coonect" for testing, it works. But when I get out of the conection testing menu, the ping dies too.
Maybe I need to upgrade unleashx? I also tried evox, by the way, and it had the same result.
