Nintendo Wi-Fi authentication could not complete

What this means

Nintendo Wi-Fi authentication could not complete.

The Nintendo Wi-Fi authentication stage failed without a more specific reason. First confirm the console has working Internet access, then verify the active connection still points at RexiMemo's DNS.

What to try

  1. Retry once after restarting Flipnote Studio. A one-off failure can be temporary.
  2. If the DSi connection test succeeds, avoid changing unrelated Wi-Fi settings.
  3. If the same code keeps returning, contact RexiMemo support and include the complete code and the action that triggered it.
