My ibook has some problem with the Airport/ Internet Connection that the Mac Genius in Tokyo could not even help. Here in Tokyo, McDonald's has free wireless connection provided by Yahoo. On Day 1, when I turned on the ibook, a message came out, like "detected an untrusted network, do you want to name it FREEPORT?". I clicked "Yes" and I got connected to internet successfully. On Day 2, in McDonald's again, I had a similar message "detected an untrusted network, do you want to name it XXX?". This time, I clicked "No" and after that I could not connected to any free wireless service by Yahoo. That message does not exist again. I think I made a mistake. How can I fix the problem? I went to Apple Store Ginza and a Mac Genius used one hour to work on it. Finally, the fact was he cheated that he fixed it successfully. Now, I am in Apple Store Shibuya. The Mac Genius wanna format my machine, which I don't want. Could anybody here help me? Thank you.
