How do I fix random MAC address?

MAC Randomization creates a random MAC address when joining a Wi-Fi network for the first time or after “forgetting” and rejoining a Wi-Fi network. It Generates a new random MAC address after 24 hours of last connection.

To ensure optimization of your HomePass® app features, you may want to consider disabling MAC Randomization on your devices. It is done on a per SSID basis so you can turn off the randomization for your home SSID but allow it to function for hotspots outside of your home.

To Disable MAC Randomization on iOS Devices:

  1. Open the Settings on your iPhone, iPad, or iPod, then tap Wi-Fi or WLAN
  2. Tap the information button next to your network
  3. Turn off Private Address
  4. Re-join the network

To Disable MAC Randomization on Android Devices:

  1. Open the Settings
  2. Tap Network & Internet -> Wi-Fi
  3. Tap the gear icon associated with your network
  4. Tap MAC address type
  5. Tap Phone MAC
  6. Re-join the network

Use random hardware addresses

There's two controls for using random hardware addresses—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 you connect to that network.

For more info about why you’d use a random hardware address, see Why use random hardware addresses?

Use random hardware addresses for all networks:

  1. Select the Start button, then enter settings. Select Settings Network & internet > Wi-Fi.

  2. Turn on Random hardware addresses.

Use random hardware addresses for a specific network:

  1. Select the Start button, then enter settings. Select Settings Network & internet > Wi-Fi  > Manage known networks.

  2. Choose a Wi-Fi network, then choose the setting you want for Random hardware addresses.

How to enable enhanced randomize MAC addresses on Android

Android 11 allows users to enable the Wi-Fi-Enhanced MAC randomization. Jack Wallen shows you how.

https://www.techrepublic.com/wp-content/uploads/2021/03/20210222-RandomMac-Jack_1.mp4

In the name of privacy, the Google developers made it possible to use a randomized MAC address, starting with Android 8. However, it wasn’t until Android 11 that the default status of MAC randomization was such that users could enable the feature. To make it even more appealing, the randomization of MAC addresses on Android 11 is network based (per SSID).

In other words, every time your device connects to a new network, it can use a randomized MAC address.

Why is this important?

To put it simply: Privacy. If your device uses the same MAC address for everything, it makes it possible for ne’er-do-wells to create a history of your activity, which could lead to far worse things. By making use of randomized MAC addresses, it becomes harder for would-be attackers to use such history against you.

It’s not the end all be all of privacy, but it’s a great start.

How to enable the new enhanced randomized MAC addresses

The feature is actually hiding from you. In order to enable randomized MAC addresses, you must first enable Developer Options. To do that, open Settings and search for Build Number (which should be found in About Phone).

Once you’ve located Build Number, tap it seven times. After the seventh tap, Developer Options will be enabled.

Go back to Settings and then tap System | Advanced and you should see Developer options listed (Figure A).

Tap Developer Options and then scroll down to the Networking section. You should see Wi-Fi-Enhanced MAC Randomization listed (Figure B).

And that’s it. At this point, every time your Android 11 device is connected to a wireless network, it’ll use a randomized MAC address. Congratulations on your new-found layer of privacy.

What does it mean when your MAC address is randomized?

MAC randomization is a process that hides the exact identity of a mobile device. It works by concealing what is called the media access control (MAC) address of that device and creating an artificial one in its place, which is then transmitted to any surrounding WiFi access points.

Should I disable MAC randomization?

For better privacy, devices running Android 10 or later use a randomized Wi-Fi MAC address by default. In some cases, you might want to disable this feature.
