I had this same exact error code. called the nintendo repair told them the code and that i did the channel 1 and 11 on my router reformatted the memory and so on. instantly said i would get the advance replacment. he explained to me that the first update you download when you plug in the wii is a firmware update. apparantly it is causing some wii's to become confused once they connect to a router hence the connection test lag followed by an error code.
