Wireless (Wi-Fi) networks operate in a frequency range of 2.4 or 5 gigahertz to transmit wireless data between routers and computers. Like any radio signal, Wi-Fi networks are affected by several variables. Distance is one of the main factors in the ability to receive a signal. If your Dell Inspiron laptop is too far away from the Wi-Fi router, your signal will be weak. Other factors that affect the signal strength of your router and receptivity of your laptop are: the number and type of walls between them, other Wi-Fi networks operating in the area and other electromagnetic radiation in the area.
