Nintendo Wii Internet Help?

Is the wii internet free? and also how do you hook it up? (what, do you take your computer and hook a line to it to the wii?, im not familiar.) thx

Suggestion:

The Internet Channel is free. You just go to the virtual store and download it.

The Wii has Wi-Fi internet, so you need a Wi-Fi connection at home. You used to be able to buy a USB or LAN adapter but Nintendo doesn't make them anymore.
