I swear my wifi wants to make my life miserable. I had a friend over, and we were gonna have a pokemon battle, so we used wifi so we would get level 100 pokemon (Rather than lvl 40s versus lvl 80s). We were 5 feet away from each other, and we get connection problems. It didn't do that when I used wifi and my brothers ds, to trade something (I was using wifi because his ds is not in as good shape as mine, because he never uses it, and the wireless is kinda unreliable...)
