Sorry for late reply.
The
Intel Centrino 6230 is a good choice, I got it my self and haven't had any troubles with that, and the notebook is "acting different" or what to say
😛 The Atheros stock wifi card is crap, shouldn't even been on the notebooks in the first place.
About the first question I can not answer since that is something I don't know..... What I know is that the 6230 car has 2 antennas and doesn't need a third one since it doesn't have that.
And about the second question I'm not sure there either.... so perhaps others from this forum could step in and give you more thoughts about it
