Hi! Thanks everybody! I have another question. As you know, the antenna cable is slightly short. As Dan did, can I just extend it by cutting the tape which is holding the cable underneath logic board..? If so, there are 2 connectors. But the direction is different between 2010 late(BCM943224PCIEBT2) and 2013mid(bcm94360cs2). 2010 late - along the hinge in a row. (https://www.ifixit.com/Guide/MacBook+Air...) 2013 mid - in a row next to screw (https://www.ifixit.com/Guide/MacBook+Air...) 1. Should I cut the cable and reconnect the cable? 2. Is there any problem from the size of both airport card? Because the 2013 mid model seems longer than 2010 model. If you help me again, I could do it by myself. Then I will update its result! haha. Thanks all!
