As it turns out, router height does make a difference. Like most people, you probably unpacked your new router, located a reasonable outlet, and left it on whatever was nearby: a shelf, a desk, or even the ground. In fact, correct positioning is one of the many ways to improve the speed of your router. Even a slight shift in position could slow down your Wi-Fi. The position of your router plays a critical role in your home Wi-Fi network.
