How to Stop Wii Updatesby Veronica SummersUpdated September 22, 2017
Items you will need
Periodically, Nintendo issues new system updates or firmware releases for the Wii gaming system. These updates are designed to upgrade your Wii with new features, enhance your Wii's performance, or fix bugs from previous releases. However, you may realize that, at times, you are better off running an old software version than upgrading to a new version with unseen problems. In these cases, you may want to stop your Wii from receiving updates.
If you are running Wii firmware version 3.4, Nintendo can automatically update your system without your approval using the WiiConnect24 service. This update can occur even if you are not currently using your Wii. To disable WiiConnect24, access the Wii settings by turning on your Wii.
Move your Wii remote over the "Wii" button in the left corner of the screen, then press the "A" button.
On the System Settings screen, select the "Wii Settings" icon that looks like a wrench, then press "A".
Click the blue arrow to access the Wii System Settings 2 menu.
Select "WiiConnect24" and press "Off." This will turn off all system updates and communications from Nintendo to your Wii. You are now safe from Nintendo updating your Wii without your knowledge.
If you'd like to manually update the Wii system software or firmware, access the Wii System Settings and click the "System Update" button. Nintendo will load the most recent update and ask you if you'd like to install it. Click "I accept" to install the latest system upgrade.
If you are running the Homebrew Channel or have modified your Wii in any way, you must be careful when installing system updates. Some updates will disable your Wii if you have modified it. In this case, it is critical to turn off WiiConnect24.
