Note I myself had an error. My wii profile disapperead from my usb wifi connector tab and the wii wouldn't connect to the internet. I had to delete the setting from the wii then rerun the find usb wifi connector reauthorize it on my comp then it would connect.
It's weird that for months instead of the english letters my identified itself by that I chose it displayed some kanji. Weirdest thing was it appears to have happened when a webpage hijacked my ie explorer homepage setting. It was redirecting to a Japanese orChinese website.Had to do some digging around in my comp to remove the virus causing that.
