|If it's possible, and I don't know that it is, you would enable ICS on your air card (to share it with the wireless NIC) and create an "ad hoc" wireless network on the laptop's wireless NIC and connect your Wii to that ad hoc WLAN.|

How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
