the problem with nintendo wifi in general is when connecting to a new AP
it likes to test the connection by contacting a nintendo server.
This is a problem because for example on a wii when configuring a new
AP after connecting it initiates a connection test with a Nintendo server.
Now if for whatever reason (nintendo servers being down, ports blocked)
the connection test is not successful then it wont allow that connection to
be used. Its a problem mainly for when wanting to use services that do
not involve Nintendo servers (internet channel).
