So here's a question haven't seen asked or answered. The new MBA with it's 802.11AC, does it run in 1.3gb or 1.75gb? I know the new Basestations are 1.3GB. But is the chip used in the MBA capable of running at 1.75GB if you have a 1750AC router? I'm still trying to track down info on the Broadcom chip that's used, but I'm just curious.
