     Thanks again for looking into this.
My main concern was the range of network performance that I was getting when 
the laptop was right in front of the access point. As you can see bandwith 
varied greatly.  
        In addition, I recently purchased an ASUS RT-AC66U Dual-band Gigabit 
router. What is weird to me is that even though the 5Ghz radio is enabled  on 
the router with various channels to use, ifconfig complains about not seeing 
channels above 13. Also, when specifically setting the router channel to 11, 
ifconfig reports that channel 1 is being used. I am not sure on what is going 
on. Is this normal?
