When troubleshooting networking issues, it is sometimes necessary to find the computer's unique MAC (media access control) address to identify it on the network. It is a 6 pair hexadecimal string of characters, is unique to each piece of network equipment in the computer, and never changes. It is also called the WiFi Address or Physical Address. Follow the directions below to find the MAC Address for your device.
