What this means
Second connection-test request failed.
These codes mean a later connection-test request failed after an earlier network step had already completed. Treat it as a network/filtering issue unless the same network otherwise works reliably.
What to try
- Run the DSi connection test again after restarting the router or hotspot.
- Check whether the network uses a captive portal, content filter or firewall that could block the console's test request.
- If normal web access on the network is also unstable, fix that network problem before changing RexiMemo settings.
