This guide provides different means of regaining WiiConnect24 functionality on your console. Although not at all nessecary, it is a "nice to have" feature that was originally used for online connectivity in certain applications on the console. These apps include the Forecast/News Channel, Nintendo Channel, Check Mii Out Channel, some Japan-exclusive channels, and more. Please bear in mind, the functionality you gain depends entirely on what service(s) you use.
Both services listed below are compatible with one another and can be loaded on the same console. With this said, it should be noted that when installing one channel over the other (WiiLink's Forecast Channel over RiiConect24's Forecast Channel for example), the channel you are installing will overwrite the old one.
A newer WC24/Japanese channel revival service that started in 2020, but is rapidly regaining functionality in many different channels. The channels that are revived are listed below:
If you choose to install either of these services on your Wii, it is advised to synchronize its external clock in order to prevent various issues that may arise otherwise. The steps to do so can be found below:
This guide takes the process of regaining online functionality to your Wii a step further - by allowing the Nintendo Wi-Fi Connection services to function yet again on certain games like Mario Kart Wii. While there are different private servers and services that allow this, the one covered here will be Wiimmfi.
