When I got on at 9 est it wouldn't connect and just sat connecting forever.... I went to play in a local match against bots and when I finished it had connected....
When I did connect there was only 300 people online so I assumed I wasn't the only one having the problem. I took a shower and when I got out there was 600 people online.
While you're browsing the available playlist, there should be a button on the side that says "Search Prefferences". Basically you can either pick a matchmaking based on the best connection or find a match based on availability (puts you in matches faster but there's a tendency of getting into bad lobbies)
Edit: Here's a summarization of all of the options available:-
-Best = Finds match based on best connection quality (greatly adviced if you have fast internet speed)
-Normal = Finds match that has a balance of best connection and availability
-Any = Puts you in any match regardless of any variables (if you're having a bad time finding lobbies, use this)
Cheers to you too mate. Just so you know, I'm having a bad time getting a U so I might get at a later date (the latest by March). Let's just say some people don't want to "co-operate"
I'll be here to provide any game knowledge that I know off that's not WiiU specific and also to know the problems and current whereabouts of the community
