What this means
None of the configured access points could be used.
This code appears when none of the console's saved access points can be used. Verify the correct saved connection before changing DNS.
What to try
- Fix the basic Wi-Fi connection first: make sure the access point is visible, in range and compatible with the DSi.
- Check that you are editing the same saved connection the console is actually using and that its security settings are correct.
- Run the DSi connection test. Only troubleshoot RexiMemo DNS after the console can connect to the access point successfully.
