Wi-Fi Range - Which Wireless Router Has the Best Wi-Fi Signal?

Question: Which Wireless Router Offers the Best WiFi Range? Consumer wireless routers vary in the Wi-Fi range they support. Routers with stronger Wi-Fi signals allow devices to connect at higher speeds from a greater distance and stay connected more reliably.
Wi-Fi (also spelled Wifi or WiFi ) is a popular technology that allows an electronic device to exchange data wirelessly (using radio waves ) over a computer network , including high-speed Internet connections. The Wi-Fi Alliance defines Wi-Fi as any " wireless local area network (WLAN) products that are based on the Institute of Electrical and Electronics Engineers ' (IEEE) 802.11 standards ". [ 1 ] However, since most modern WLANs are based on these standards, the term "Wi-Fi" is used in general English as a synonym for "WLAN". Only Wi-Fi products that complete Wi-Fi Alliance interoperability certification testing successfully may use the "Wi-Fi CERTIFIED" trademark. A device that can use Wi-Fi (such as a personal computer, video-game console, smartphone , tablet , or digital audio player) can connect to a network resource such as the Internet via a wireless network access point .
