Updating wii without internet
The system will download and install updates automatically As long as your Wii is connected to the Internet, you will be able to download updates.Once connected, the Wii will tell you that an update is available by flashing.If you see your Wii light up, follow the update steps.
I heard the wii u is like 5gbs to update which is insane for a phone connection is there another way to do it?
As another poster said, the best solution would be to take the Wii U and Wii to a house that has internet access and do it there.
Click "Search for Access Point" to make the Wii search for the wireless network.
Click "OK" on the screen that reads, "Choose which access point you want to connect to." This will bring up a list of wireless networks that the Wii picks up.
Click the "Wii" button in the bottom left-hand corner of the screen by moving the cursor over it and pressing the "A" button on the Wiimote.
