How to Find Your WiFi SSID on a Computer: A Comprehensive Guide

Understanding your WiFi network is crucial for various tasks, from connecting new devices to troubleshooting network issues. The Service Set Identifier (SSID), commonly known as your WiFi network name, is the first piece of information you need. This article will provide a detailed, step-by-step guide on how to find the SSID on your computer, regardless of whether you’re using Windows, macOS, or Linux.

What is an SSID?

Before we dive into the ‘how,’ let’s understand the ‘what.’ An SSID is essentially the name of your WiFi network. When you scan for available networks on your computer, phone, or any other WiFi-enabled device, you see a list of SSIDs. Each network has its unique SSID, which allows devices to identify and connect to the correct wireless network. Without knowing the correct SSID, you cannot connect to a specific network.
