I recently got the new MacBook Air and also the Airport Extreme Bas Station. I got them both hooked up and the computer is receiving a wifi signal fine, I just don't think I am getting the ac speed. I transferred a fairly large movie file and it seems like it is taking about the same time it used to take on my old MBP. Anyway, I just want to know how in OS 10.8.4 I can verify what type of connection I have. Also, If I find I don't have ac, what can i do to fix this? Thanks.
