MacBook Pro 15" Core 2 Duo Model A1211 Airport Extreme Replacement

Moderate

Mi Problema

My girlfriends macbook starting having issues connecting to the wireless router. The airport finally lost it's ability to turn on at all. So I had to replace the airport card.

Mi Solucion

It all went pretty smoothly until I opened the anti-static bag with the new MacBook Core 2 Duo 802.11 Airport Extreme Card.

Mi Consejo

Upon opening the anti-static bag with the new airport card in it I noticed something.

The new card had 3 little antenna slots for the antenna cables where as the old one only had 2.

I was baffled as to why there was a 3rd antenna port and how to connect it up with the 2 I had available.

I checked online again to make sure I got the recommended hardware from iFixit's Airport repair page for the proper macbook model, I triple checked the model to make sure I was looking at the right one.

I googled a solution and found a few people having the same problem I had but no one had a solution so I was left with trial and error.

The new MacBook Core 2 Duo 802.11n Airport card had 3 antenna ports and I had 2 antenna to connect to it.

Each port was labeled 0, 1 and 2. So I decided to plug the open macbook into the wall and do some trial and error. I plugged in 0,2 at first and that actually worked for a few minutes until it no longer connected and then refused to turn on.

I connected 1,2 and that failed completly. No connection what-so-ever.

I then connected 0,1 and success! The Macbook booted up, connected to one of our wifi networks, I turned the airport off and back on and connected to another network just fine. I rebooted once more just to be sure and it still worked so I closed it up.

TL;DR For those of you using the new Airport card with 3 antenna ports in an old 2 antenna cable system, the ports you want are 0 and 1.
