Description
There are two controls for using random hardware addresses. One is for all Wi-Fi networks, and the other is for your specific Wi-Fi network. When you turn the control on for all Wi-Fi networks, random hardware addresses are used while your PC scans for networks and then connects to any network. When the control is turned on for a specific network you choose, random hardware addresses are used the next time you connect.

Why use random hardware addresses?
When you are not connected to Wi-Fi, your PC sends a signal to look for Wi-Fi networks in the area to help you get connected. The signal contains your device's unique physical hardware (MAC) address. Some places (i.e., shopping malls, stores, or other public areas) might use this unique address to track your movements. If your Wi-Fi hardware supports it, you can turn on random hardware addresses to make it harder for people to track you when your PC scans for networks and connects.
Impact on campus
The DeviceNet wireless network on campus uses your hardware address to verify which computer you have registered. With random hardware addresses turned on in Windows 10, your hardware address will change periodically, making it not work correctly.
