There is a wi-fi connection that I have used for my Wii, but I don't know where the base is or who runs it. I don't want to transmit any information like my credit card over that connection.
I was hoping I could use Airport on my iMac to create a connection. I set up a network, and the Wii can find it, but it tells me the password is wrong. Is it possible to use a computer as a connection?
