My Samsung Galaxy Book4 pulled 41Mbps at my desk one Tuesday night, on a 500Mbps fiber plan, from an ASUS TUF Gaming AX4200 two rooms away. Smart Connect, which is ASUS’s name for band steering, had parked it on 2.4GHz again, the crowded band my smart plugs already fight over. I’d blamed the drivers, the laptop, and the bathroom wall, in that order.
