First of all, thanks so much for the fix. Incredible work!
As I've read the forum posts, I believe this is all I need and not an adapter. Am I right?
I see the BCM94331PCIEBT4CAX for my early 2011 17" MacBook pros on eBay. I don't see "CAX" on the photos of the cards. Should I be concerned with that? With these coming from China or Hong Kong, to return these is pricy.
Is there a known good place to buy BCM94331PCIEBT4CAX?
- You need the BCM94331PCIEBT4CAX card but no adapter. The card will fit your machine directly. If I were you, then yes, I would be concerned about the pictures not depicting the correct card. The full model number should appear on the opposite side of the card to the one that holds the antenna connectors.
For your reference, I've purchased this one for my Early 2011 15" MBP. Notice the model number on picture number two towards the top of the card.
