To enjoy the best possible online experience, your router needs to be able to send out a strong signal to your wireless devices, wherever you are in your home. In general, the signal gets weaker the farther you are from your Wi-Fi router. If possible, you should place the Wi-Fi router on a shelf. The ideal position is half-way between the floor and the ceiling.
The physical features of your house may also contribute to WiFi coverage issues. For example, walls made from concrete or brick, or with steel studs behind the drywall, can block some — or all — of your Wi-Fi signal.
Metal surfaces can also weaken your Wi-Fi signal, so placing your router in a kitchen or laundry room (where there might be a lot of metal appliances) is not a good idea. Finally, one of the most obstructive materials for Wi-Fi signals is a mirror. If you have a sizeable mirror near your Wi-Fi router, it may negatively impact Wi-Fi performance.
If you are experiencing Wi-Fi issues, try moving your Wi-Fi router to a different room in your house. Or, consider adding a mesh device to improve the coverage to all areas in your home.
