Why is my Laptop not connecting to WiFi?
Understanding the Basics of WiFi Connection
Before we dive into the possible reasons why your laptop is not connecting to WiFi, it’s essential to understand the basics of how WiFi works. WiFi is a type of wireless networking technology that allows devices to connect to the internet or communicate with each other over a range of distances. A WiFi router is typically located in a central location, and it broadcasts a unique identifier (SSID) that devices can connect to. Your laptop needs to be within range of the router and have a valid login credentials to establish a connection.
