You've probably heard by now that Wi-Fi router placement can play a big role in its performance. But what about a Wi-Fi router on the floor? The reason is that if your router sits on the floor, a lot of the Wi-Fi signal gets lost into the ground. So, when you put your Wi-Fi router on the floor, a good chunk of that signal goes directly into the floor instead of where you need it. Due to this, you should always strive to position the Wi-Fi router somewhere elevated, like a shelf.
