One WII error that seems to happen quite frequently is the WII Error 11021. It in general appears after updating WII using WII connect. What should you do? Give Nintendo a call. I was told that there is a hardware error. I can play games without problems, but the system cannot upgrade the WII. I was told to return my game console to Nintendo and that they will ship a new one. That was 10 days ago…. no new game station has arrived here although Nintendo keeps telling me that it has already been shipped. I hate it when things like that happen.
