Ask Max: Macbook Pro Wireless Connections
I recently purchased an upgraded wireless card from PowerMax for my MacBook Pro. The new card only has two antenna connections with no identifying marks correlating with the three connections in the laptop, while the old airport card had three that are clearly labeled. The spacing between the two connections on the new card would suggest use of the middle connection is not required, but this is an assumption. We all know what ™assumption™ stands for. Can you shed any light on this?
I assume (ha!) you are using the Mac Pro wireless upgrade kit to add 802.11n to your pre-N MacBook Pro. In that case there is sometimes an ™extra™ antenna cable. There are two things to remember when dropping one antenna from a three-cable wire harness. The first is that you want to cap the metal end of the unused antenna cable. The second is that you want to use the black and blue cables with the new card, and cap the grey cable. If the cables are not color coded, the middle cable is the right one to cap.
