Netflix on Wii Ended January 31, 2019 — Use Switch, PS4/5, Xbox, or Streaming Stick

You can't. Netflix ended support for the Wii on January 31, 2019. The channel was removed from the Wii Shop, and the app no longer functions.

Modern Alternatives for Netflix

• Nintendo Switch — Netflix app available (eShop)
• PS4 / PS5 — Netflix app
• Xbox One / Series X|S — Netflix app
• Streaming Sticks: Fire TV Stick, Roku, Chromecast, Apple TV (all <$50)
• Smart TV / Blu-ray Player / PC / Phone — Native apps everywhere

The Wii's hardware (no HTML5/DRM support, 480p max) cannot meet modern streaming requirements. Upgrade to any device above for HD/4K Netflix.
