Understanding MAC Addresses
Before diving into the methods, let’s understand what a MAC address is and why it’s essential.
MAC (Media Access Control) address is a unique identifier assigned to every network interface card (NIC) in a device. It’s like a digital fingerprint that distinguishes your Acer Aspire 3 from other devices on the network. Each MAC address is a 12-character hexadecimal number, often displayed in pairs separated by colons (e.g., 00:11:22:33:44:55).

1. Open Settings: Click the Start button and select “Settings” (gear icon).
2. Navigate to Network & Internet: Click on “Network & Internet” in the Settings window.
3. Select Wi-Fi: Click on “Wi-Fi” from the left-hand menu.
4. View Network Properties: Click on the name of your connected Wi-Fi network.
5. Locate MAC Address: Scroll down to the “Hardware address” section. Your MAC address will be displayed here.
