Setting Up Internet on Nintendo Wii: Wi-Fi & Wired (USB-Ethernet) Guide

Wii has built-in Wi-Fi. Wired needs a USB-to-Ethernet adapter.

Wi-Fi (Recommended)

1. Wii Menu → Wii Settings (bottom-left round button).
2. Internet → Connection Settings.
3. Pick empty slot → Wireless Connection → Search for Access Point.
4. Select your SSID → enter WEP/WPA/WPA2 password.
5. Save → Connection Test.

Wired (USB-Ethernet Adapter)

1. Plug adapter into Wii USB (back).
2. Ethernet cable: router/modem → adapter.
3. Wii Settings → Internet → Connection Settings → empty slot → Wired Connection.
4. Auto-detects → Connection Test.

Note: Wii Shop Channel closed Jan 2019. Online game features (e.g., Mario Kart Wii via Wiimmfi) may still work.

Troubleshoot: update router firmware, disable MAC filtering for Wii.
