I'm getting a thing on my wifi that says "no hardware installed" I took it to the genius bar and they said it was the airport card. They want to charge $100+ to fix it. Should I do this? I mean if thats the issue. And finding this part on the internet is kinda hard. Its a 2009 macbook pro. --- If you're going to kill someone or commit suicide, rob a bank first, if you get away with it you'll make the first two options utterly useless.
