There are three physical considerations to review when you try to optimize your wireless Internet service. First, WiFi is a radio wave that moves easily through open spaces but can be interrupted or stopped by physical obstacles such as walls or doors. Parma explains that this can be a particular problem in older buildings with metal mesh, pipes or wires in the walls.
Second, the wireless Internet signal becomes weaker as the distance from the router increases. Although it might not always be the best aesthetic choice, you will get the best wireless Internet service throughout a space if the router is in a central location. Another tip is to elevate the router.
Third, keep your router away from electronics and appliances that can interfere with WiFi. These include microwave ovens, devices using Bluetooth connections, security cameras and older cordless telephone systems.
