@mwto See? This is what I'm talking about. I could trade fine too, up until today. I know at least 4, now 5 with you, who are just suddenly getting this code today. If it were truly the firewall's fault, why would this be happening JUST today with MANY people? After all, these people have made dozes, some of them maybe even hundreds, of successful trades. Seeing as there is a raising number, things point to something is wrong with Nintendo's Wi-fi.
