Hi,
I have been having problems for the past week trying to connect to multiplayer games on nintendo wi-fi. I connect to Nintendo wi-fi itself but cannot connect to any games. When trying it tries to for ages then I get disconnected wth the following error codes:
85010, 85020, 61020 & 92020 'communication error...you have been disconnected from nintendo wifi connection'. The week before it worked fine and I have tried connecting when no-one else is using the connection.
I have checked all the connection settings etc and they are fine.

Maybe the server is down? At any rate, most of Nintendo WiFi is controlled by Nintendo, not Team17, so you'd be best asking them.
