I also saw the smart connect feature listed for the AC-3100 on Asus' website but I didn't look in the router settings to see if it was there. Honestly it isn't something that concerns me with a dual band router, as that is something that would be more beneficial when you have a tri-band router and even then it still isn't working that well for most people. So that is not something that I think is necessary to have anyway.AC88U has this Smart Connect, according to spec on Amazon and manual. is AC3100 the same as AC88U? beside number of ports.
I'm more interested in a stable version of Merlins firmware.
