    Error code 101-0744

    What does this error code mean?

    This error occurs when users try to use network communication without registering their Nintendo Network ID.

    What can I do?

    A Nintendo Network ID (NNID) is required for most online games and applications, and also to download free software or demos on Nintendo eShop. Please create an NNID by following How to register a Nintendo Network ID on Wii U.

    Please note: each NNID can be associated to only one Wii U console and one Nintendo 3DS family system.

    If the solutions suggested above don’t solve your issue, please take a note of the following information and Contact Us:

    • Serial number of your Wii U console.
    • How the problem occurred. For example the name of the game/application you were using, or at which point the problem occurred.
