What this means
Nintendo hotspot authentication could not reach NAS.
These codes belong to the old Nintendo public-hotspot sign-in path and mean it could not reach the Nintendo Wi-Fi authentication service. On a normal home network, recreate the connection as a standard access point instead of using an obsolete hotspot profile.
What to try
- Do not use an old Nintendo hotspot or Nintendo Wi-Fi USB Connector setup for RexiMemo.
- Create or use a normal DSi-compatible wireless connection instead.
- After the normal connection works, apply the RexiMemo DNS from How to Join.
