I checked again to make sure, it's my Brawl FC. I just didn't add anyone yet. I'll add everyone on the list as of this post. Also, I was playing a neighbor in my apartment complex. Rooms were on the same floor, and somehow there was some crazy amount of lag. And the connection dropped after the 5th match.
EDIT: My bad, seems you did take the Wii Console code instead of SSBB. They're in the same place. 2578-2800-5058
