A co-worker bought a 3DS and we tried to do local friend exchange during a break. It sometimes found me, and sometimes I found him. Anyway when we clicked on the card it would process but ALWAYS receive an error and not save the new friend. I was sitting less than a foot away from him so no clue why it took so long to find me or why it never completed the friend exchange.
Any suggestions? Wireless was on for both of us, and we already street passed each other fine. I checked my parental settings and it allows local friend exchanges. So I have no clue what the problem is.
