My sister-in-law gave us her Wii because her new husband also has one but the Neflix channel had already been downloaded by her. I erased the channel then downloaded it again assuming that I would be prompted to enter my account information. However, when I started Netflix after that, it did not prompt me to sign-in. How can I change the account information associated with the Netflix channel? Any help is appreciated! Thank you!
Welcome to Nintendo's Tech Support Forums
If you haven't already, try deleting the saved data for Netflix. The saved data is separate from the Wii Channel information. It sounds like you deleted, and downloaded, the Netflix Wii Channel again. For additional information, please visit:
Have you tried contacting Netflix? They may have additional information in regards to removing the connection between a Wii console and someone's Netflix account.
Try deleting the save data of the channel, if you have a Wii game that has no save data and does not create a new save data file once loaded, you will not be able to save the progress of your game. If this does not work, contact Netflix of Nintendo. Before contacting Netflix, check if you can delete your Netflix from your Wii on Netflix's official site.
