What is a Wi-Fi extender?
A wi-fi extender is a device that helps to get a signal in a house or office where the signal strength is low. It uses a wired connection to boost the signal of your wi-fi router.
What is a booster?
A booster helps to amplify the wi-fi signal that is weak, to reach a far distance. It uses a wireless connection to boost the signal of your wi-fi router.
Wi-Fi extenders are devices that pick up the wireless signal and boost it to provide a better connection to the users. However, there is a lot of debate about whether Wi-Fi extenders are effective or not. The answer is yes and no. Wi-Fi extenders work by amplifying the signal. This means that if your wireless network is strong, then your Wi-Fi extender will simply boost the signal and it will not have much of an effect. However, if your wireless network is weak and your Wi-Fi extenders are strong, then the Wi-Fi extender can boost the weak signal for you. The problem is that many people get a Wi-Fi extender and expect it to double their signal, when in reality the effect is not that significant.
