Why is my Lenovo Laptop not connecting to WiFi?
Understanding the Basics
Before we dive into the possible reasons why your Lenovo laptop is not connecting to WiFi, let’s first understand the basics of how WiFi works. WiFi is a wireless networking technology that allows devices to connect to the internet or communicate with each other without the use of cables. It operates on the 2.4 GHz and 5 GHz frequency bands, which are divided into two main categories: Infrastructure Mode and Ad-Hoc Mode.
Infrastructure Mode
In Infrastructure Mode, devices connect to a Wireless Access Point (WAP), which is a device that broadcasts a signal that allows devices to connect to it. The WAP is usually connected to a Router, which is a device that connects to the internet and provides access to the internet for all connected devices. The WAP and Router are usually connected to the same Internet Service Provider (ISP), which provides the internet connection.
Ad-Hoc Mode
In Ad-Hoc Mode, devices connect to each other directly without the use of a WAP or Router. This is useful for devices that need to communicate with each other in a specific area, such as a home network or a conference room.
