Would you be willing to answer a few brief questions about PlayStation Forums?
I thought this was common sense.
This works on the vita but its not gonna work on the ps3 if the game freezes on the search for opponents screen.
I'd recommend storing your matches in an easy to reach area. I keep mine in the drawer on the underside of my barbeque so that I never have to go looking, saves me a ton of time looking for a match and I've never had to restart my search.
It's kinda funny that they've fixed the disconnection issues, but you have to disconnect to find a playable match.
