FWIW I picked up an Asus RT-AC66U last week. My wifi range has improved dramatically over my Netgear WNR-3500L router, and I'm seeing about a 50% increase in my wifi speed. That says more about my oldĀ router IMHO, but I have to say I'm pretty happy with the unit so far.

The unit is located in my office, which is in my basement. I actually have the router more or less centered in between a couple of joists in the basement. I have no problems with signal through the rest of the basement or on either the 1st or 2nd floor of the house.
