I went through this because after replacing the top case, upon restart the Airport card was not recognized. I was hoping the cable had come loose, as resetting PRAM and SMC didn't fix the issue (and searching the web, a LOT of people have this issue, most without having touched the internals of their Mac). That was not the case, everything appeared correct. So I got a USB wireless dongle and called it good.

I did it! \o/

The guide was really helpful. Be careful with all the delicate connections and DO NOT attempt to use not guide-specified tools. Yeah... You heard me, buy a decent Torx tool. :)

Very accurate guide. Much appreciated.

Thank you very much for this guide. No real problem with the good tools! After restart, the wifi comes back! Yes!!! But just a little problem … the white becomes suddenly blue and impossible to change that. I open a second time to disconnect and connect the LCD wire. It seems to be ok but after mounting the screws, my blue problem comes back! Do somebody have an idea?
