Wi-Fi signals slow down when passing through walls and obstacles, with some materials causing more disruption than others.
Wi-Fi signals weaken through walls
Wi-Fi signals slow down when they pass through walls and other obstacles in a home. This happens because the radio waves used for Wi-Fi lose strength when they meet different materials.Different materials affect signals differently
Some common household materials have a bigger impact on Wi-Fi signals than others. Thick stone or reinforced concrete walls, for example, reflect and absorb more of the signal, while lighter materials like plasterboard or wooden doors cause only a moderate slowdown.Everyday items also interfere with Wi-Fi
Items like large aquariums, microwave ovens, refrigerators, and mirrors with metal layers can also slow down Wi-Fi. These objects absorb or reflect the radio waves, reducing the signal strength and speed.Wi-Fi frequencies behave differently
The 2.4 GHz Wi-Fi band has slower speeds but can pass through more walls, covering a larger area. Newer 5 GHz and 6 GHz bands offer faster speeds but lose strength quickly when encountering thick walls, leading to a noticeable drop in speed when moving between rooms.Solutions for better Wi-Fi coverage
To ensure consistent Wi-Fi performance across a home, users may need to use a repeater or a mesh network. These systems help extend the signal and maintain stable connection speeds in areas with poor coverage.
