I updated my MacbookPro8,2 early 2011 to have Bluetooth 4.0 by doing a direct swap of the airport card with a BCM94331PCIEBT4CAX from a 2012 MacBook Pro and running. But I can't seem to find out what wireless protocol it is: 802.11 a/b/g/n/ or ac.
Airport Extreme 802.11ac, OS X Yosemite (10.10.4)
if you option click on your wifi icon at the top of the screen, it'll tell you what wireless protocol your network is. As for what the card supports, go to the Apple symbol at the top left of your screen, click on "About this Mac" then "system Report" or "More info"and your card should be listed there if it' s working OK
(It's under Wifi) and it'll tell you its name and what it supports, same with Bluetooth

Your "options click" suggestion only reveals the specs on the current wi-fi connection, but you're "about this mac" suggestion was on the money.
FYI - Supported PHY Modes: 802.11 a/b/g/n
Thank you for the suggestions
BCM94331PCIEBT4CAX is 802.11?
