Well I messed things up when I tried to create a closed network. I ended up taking it in to the Apple store yesterday and they helped me at the genius bar. He had to reset my Airport a couple of times. I took that in with my powerbook. When I got home it was not owrking so I reset m airport again and finally it was working. Now my base station is not showing up on my computer and I cannot connect to the internet. Any ideas as to what I could try? Or do I need to buy a new airport to get it to work?
