Chosen Solution

I would like to replace the 802.11n card in my mid 2012 15" unibody with 802.11ac, but I can’t seem to find one that is actually available and has any reviews saying it will work in my hardware. If anyone has a source for a viable card I would greatly appreciate the info.

@crayzjake Phillip - Apple never offered an upgraded board for the older MacBook Pro’s. As it turns out BroadCom the maker of the part sold this part to many different laptop makers and for a while they did produce an AC & BT 4.0 version of the board that fits your system. We had gotten a dozen or so when they first showed up from QuickerTEK. Then they just stopped being made or available for some reason. Apple used two different board designs the older one used a ribbon snap-on connector on the face of the board Older board version When Apple intro’ed the Retina models they went to a different design Newer board version. The newer board offers AC & BT 4.0 unlike the older board Apple used and sold as a spare.

In the past I’ve had really great success with (and referring to) PowerBook Medic for replacement parts. They stand by their stuff with a solid warranty.
