Hey
I’d be happy to help with tethering your iPhone to your Nintentdo Wii!
After setting up your hotspot on your iPhone, you will see the name of the network and the password for your hotspot displayed on the screen. In order to connect to the device on the Wii, you would access the connection settings and choose the “Easy” connection mode. It will display the available WiFi networks. Choose the name of your iPhone hotspot network, and enter the password displayed on screen. Your Wii should then be using your hotspot!
Please remember that Netflix can use a lot of data very quickly. You can monitor your data usage online via myAT&T or by dialing *3282# from your device to have a text message with usage details sent directly to you.
If this helps, please mark this answer as an accepted solution!
Thanks,
Charise
