Did you know that Wi-Fi waves are basically radio waves, with a shorter wavelength? Both Wi-Fi and radio waves (also used by mobile phones) fall under electromagnetic waves, but the difference between them is that Wi-Fi ones are significantly shorter (they are only 12 centimeters long compared to radio waves, which are several hundred meters) and therefore cannot extend further than approx. 45 meters. In addition, the signal is weaker with the distance from the wireless router, so we often encounter poor Wi-Fi signal quality. But by following simple instructions, you will get a stronger wireless network signal at zero cost.
