Logically, when you look at an antenna for anything, you think that having as much height as possible would be optimal, as in theory, this provides as much coverage as possible. So you tear open the box of your shiny new router, screw the antennas into their threaded posts, and stand every single one of them bolt upright, like a row of tiny radio towers. It looks tidy and intentional, but it’s actually killing your Wi-Fi performance. Vertical-only orientation is one of the most persistent Wi-Fi myths in consumer tech, and it quietly creates coverage gaps, leaves multi-antenna hardware underutilized, and causes performance issues that owners usually blame on their router, their ISP, or their walls.
