The connection to your opponent has been lost, end game

[JTRaines92]

This has happened twice to me on the VSNDaily_Com account. The first time was in a GB, the match didn't show up on EASports.Com but it gave me a loss. The second time it happened was just now, I was up on a level 9 (I'm level 1) 10-0 and it did it again. Are there specific ports that need to be open? I've finished a game so I know I'm capable of playing and finishing games. I am using a wireless connection if that matters. Could the signal be temporally dropping? I have no idea, any help would be appreciated.
