When you’re 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 the unique physical hardware (MAC) address for your device. Some places, for example shopping malls, stores, or other public areas, might use this unique address to track your movement in that area. If your Wi-Fi hardware supports it, you can turn onÂ random hardware addressesÂ to make it harder for people to track you when your PC scans for networks and connects.
There’s two controls for usingÂ random hardware addressesâ€”one is for all Wi-Fi networks and the other is for the specific Wi-Fi network you choose. When you turn it on for all networks, random hardware addresses are used while your PC scans for networks and connects to any network. When it’s turned on for a specific network you choose, random hardware addresses are used the next time youÂ connectÂ to that network.
This tutorial will show you how to turn on or off use random hardware (MAC) addresses for Wi-Fi networks in Windows 11.
