How Long Does It Take To Download a System Update?
Important: Please do not power off your Wii U Console during the System Update.
The length of time it takes to perform a system update varies depending on the speed of the Internet connection used. Please be patient.
Due to the amount of new features and applications included, the system update may take an extended amount of time when performed during the initial setup (for some users it could take an hour or more to download and install). Do not power off your Wii U console during this time.
