Understanding the Basics of Wi-Fi Hotspots

A Wi-Fi hotspot, also known as a virtual router, allows your laptop to share its internet connection with other devices, such as smartphones, tablets, or other laptops. This is particularly helpful when you only have one internet connection available, but multiple devices need to be online. Think of it as your laptop becoming a personal Wi-Fi router, broadcasting a wireless signal that other devices can connect to. Before diving into the how-to, let’s clarify some key concepts.

The underlying technology that enables this sharing is often referred to as “tethering.” Tethering essentially uses one device’s internet connection to provide internet access to other devices. There are different types of tethering, including USB tethering (connecting devices via USB cable) and Bluetooth tethering (using Bluetooth to share the connection), but we’ll primarily focus on Wi-Fi tethering in this guide.

It’s crucial to understand that your laptop needs an active internet connection to share it as a hotspot. This connection could be through Ethernet, Wi-Fi (from another router), or a mobile broadband connection (using a SIM card). The type of internet connection your laptop uses will determine the speed and reliability of the hotspot.
