The intensity of your Wi-Fi router's signal is heavily influenced by its position. For better Wi-Fi signal performance, place the system in a high, open space with few obstructions. Signals pass perpendicular to your router. Many of your Wi-Fi signals can move horizontally along the floor if your router is on the ground, reaching less areas of your house.
If you have a multi-level home, you can be able to boost the signal and increase your internet speeds by placing the router on the second floor. If you put your router too close to concrete or stone, it won't be able to broadcast to the rest of your house.
