Sorry in advance if this has been beaten to death on here but I have been at this for 3 days with no success finding a solution and hopefully someone can help me avoid the $700 repair on my AppleCare expired 17" MacBook Pro! My Airport Card is fried, the Genius Bar concluded I need to replace my logic board as which is connected to the Airport Card internally which I personally would rather buy a new book rather than invest on repairing this one. Problem is with all of this talk about a possible new redesigned Pro possibly out next year, i dont want to be stuck with a dinosaur before I can pay the same amount for the latest and greatest. I can get online via ethernet of course but I am going on vacation next week for 3 weeks and the ONLY internet access in the building is wireless. IS there a way to use/convert my Airport Express Base Station into a wireless receiver by connecting into it from my laptop via ethernet? The Genius Bar guy mentioned something about 'repeating' but that only seems possibly by connecting directly into the source feeding the internet signal, basically I need to replace my internal Airport signal with another source. And YES, I tried the USB wireless adapter idea, 2 of them actually, neither worked, possibly because both didn't have Snow Leopards driver updates and the 10.5 ones lay dormant. I am trying to prolong the life of my laptop's usage by alternative measures of getting online wirelessly, please tell me someone can help!!!!
