Nintendo Wi-Fi Connection was an online multiplayer gaming service for the Wii, allowing free online play. While different games were supported for longer than others, all games are no longer able to play through conventional means as of August 2023. To regain Nintendo WFC functionality, this guide provides instructions on installing Wiimmfi. There are several different methods to connect to Wiimmfi listed in order of least to greatest difficulty - choose the method that suits your situation best.

If you get error 23904 while connecting to Wiimmfi, then you are using an outdated patch.<br> Follow the steps below for the method you're using to connect to Wiimmfi again.<br> See [this page](https://wiimmfi.de/update) for more details.<br>

### No-Homebrew (Disc)
