Internet Unlock Code on Nintendo DSi – Doesn't Exist
There is no "internet unlock code" for the Nintendo DSi. The console connects to Wi-Fi directly — no code required.
How to Connect (Standard)
System Settings (wrench icon) → Internet → Connection Settings.
Choose "None" → Search for Access Point.
Select your SSID → Enter WPA/WPA2 password (DSi supports WPA2-AES; original DS only WEP).
Test Connection → Success.

Parental Controls PIN: 4-digit PIN to restrict internet / purchases. If forgotten: Inquiry Number → Nintendo Parental Controls Reset (requires email on file).
