My friends and I have been hooking up 3 xbox 360s to play Halo reach LAN games on. Everyone once in a while, two out of the three of us will get the blacks screen (where it goes to the loading screen in the middle of the game) for about 15 seconds. We're all pretty competitive so its messing up our games. It happens regardless if I am host or not. Again, this is all a WIRED connection, no wireless involved. We're connected through an ethernet hub. Any ideas on how to fix it?
