The Asus however offers smartconnect aka band steering, the option of moving your WiFi clients automatically from 5Ghz #1 (high band, more speed, less range), 5Ghz #2 (low 5Ghz band, a bit less speed, a bit more range), and 2Ghz (less speed but much more range). The Nighthawk only supports handoff between its two 5Ghz bands.
