I have noticed that the Wii I don't support the 5g, and my 2.4g internet connection is the slowest connection ever, and when I play splatoon,my favorite game, after 10 seconds it disconnects me from the internet. Also as a fact sometimes my Wii I blocks me from connecting to internet. ( I don't remember the code) I can't share my internet because I don't have mobile Internet and it don't work with usb. (I don't have the Nintendo's adapter) someone knows how to help with that ?
