Hello all; I've got a problem and I was hoping someone could help. So I've got an airport extreme base station that I've tried to set up multiple times. I followed the instructions in the manual and used the airport admin utility and airport setup assistant. I even enlisted my brother who's a hardcore mac fiend and he couldn't figure out the answer. My computer, an ibook, recognizes that it's getting a strong signal from the airport, but whenever I try to get onto the internet, I can't do it. It's like the computer knows that the airport is there and working, but that it just can't communicate with the computer. Any thoughts, suggestions, tidbits of info? Thanks.
