When I play with certain friends online I often get dropped. The game will be playing with virtually no lag, then all the sudden bam, the game freezes I get a Smash loading symbol her a strange sound effect, and get sent to a 'no contest' screen. Then I have trouble re-connecting to my friend without leaving online and coming back.
I've tried putting my 3DS into a DMZ, but it doesn't seem to help.
What's going on?
