Wireless, Finding your device's MAC address

Providing a MAC address for your device is vital to troubleshooting issues with connecting to the campus network. Please use the information in this article to ensure that you are providing the correct address for escalated troubleshooting.

For instructions on finding a MAC address on a variety of devices, see Finding the MAC address on different devices (article courtesy of Northwestern).

Important note about MAC address randomization:

Some device manufacturers have began to offer MAC randomization options in the network settings of their devices to increase privacy for users. This can cause issues for us when troubleshooting though, as the MAC address provided may not show up in logs consistently. Apple has recently turned this mode on by default, and some Android phones may have it also.

Identifying a randomized MAC address

On Android phones after tapping on the network name in the Wi-Fi menu, you will see it under the Advanced > Privacy headers. Tap Privacy to change between using the device MAC and a randomized one.

On iOS (Apple) phones, after clicking on the network name you will see a setting for "Private Address". This turns MAC randomization on and off.
