How to Find Your MAC Address
To diagnose network issues, CUS may ask you for your computer's MAC (Media Access Control) Address--a unique identifier for every wired and wireless network adapter. Here are step-by-step instructions on how to find this information.
How to find your MAC address on Macintosh OS:
- Open a new Finder window, and navigate to the Applications folder.
- Within Applications, navigate to the folder labeled "Utilities" and open the application named "Terminal.app".
- If you are using an Ethernet cable to connect to the network, type ifconfig en0 (for wireless, type ifconfig en1) in the Terminal window and press Enter. You will see a few lines of information pop up in the window. It will look something like this:
- Look for the line starting with "ether" and then followed by a series of 12 hexadecimal digits separated by colons. You will find your address in this line. In the example above, the MAC address is: 00:16:cb:b1:b4:c4.
- Open the Command Prompt in Windows. This can be done easily by typing cmd in the search bar of the Start menu (or Start > Run).
- From the command prompt, type ipconfig /all into the window and press enter. A lot of information will be displayed, but do not feel overwhelmed by it!
- If you're using an Ethernet cable, look under the header "Ethernet adapter Local Area Connection" (for wireless, look under "Ethernet adapter Wireless Network Connection"). You should see a line labeled "Physical Address" followed by a series of 12 hexadecimal digits separated by dashes. This is where you will find your MAC address. It should look something like this:
