Apple has changed the way iPhone and iPad connect to Wi-Fi networks starting with iOS 14 and iPadOS updates 14 . If this causes problems with a Wi-Fi network, you can turn it off for that network. Here's how.
How private Wi-Fi addresses work
When an iPhone, iPad, or other Wi-Fi enabled device connects to a Wi-Fi network, it sends a unique Multimedia Access Control (MAC) address . This identifies device on the network.
Traditionally, the MAC address was set at the hardware level and was the same for the lifetime of the device. Every network you connect to has received the same MAC address of your device. You can change your MAC address manually on certainins devices, but few people have done it.
It's easy to see how this feature could lead to tracking: if you move around a city connecting to different public Wi-Fi hotspots in cafes, airports and libraries , your device uses the same MAC address to connect to each, which allows an organization running Wi-Fi hotspots to track your location movements and network activity over time.
With private Wi-Fi addresses, eL 'iPhone, iPad, and Apple Watch will now provide a different MAC address for each Wi-Fi network they connect to. Each Wi-Fi network you connect to receives a different MAC address from your device. Your Wi-Fi sessions from different Wi-Fi networks can no longer be so easily linked together.
How Private Wi-Fi Can Cause Problems
Most of the time you won't notice a proproblem with private WI-Fi addresses. This option is enabled by default and will work “only”. In some cases, this will cause problems with some networks.
For example, someone may have configured a Wi-Fi network to use MAC address filtering , only allowing certain devices to connect. Your organization may require you to turn off private Wi-Fi addresses in this situation. At home, you may have set up parental controls for each device on your Wi-Fi network, a feature that uses MAC addresses to identify and apply restrictions on devices.
If you are having difficulty connecting to or accessing the Internet over a Wi-Fi network, disabling this option is a troubleshooting step that will resolve your issue in some situations.
How to disable private addresses for a Wi-Fi network
The "Private address" option is coChecked separately for each Wi-Fi network. We do not recommend that you turn it off for a network unless you need to do so (or if you are fixing a problem.)
To find this option, go to Settings> Wi-Fi on your iPhone or iPad. Locate the Wi-Fi network for which you want to change this option. It will be at the top of the screen if you are currently logged into it. Tap the "i" icon to the right of the Wi-Fi network name.
Disable the "Private address " option by tapping the switch to its right.
The "Wi-Fi address " option here shows you the private MAC address used on that specific network, just in case you need it - to configure something on a router, for example.
You will be prompted to join the network if you are already connected. Press "Join " and your iPhone or iPad will join with its normal MAC address.
On an Apple Watch, the process is the same: go to Settings> Wi-Fi, tap the name of the network you've joined (or swipe left on a network and press the "… " button if you are not already connected to it), then deactivate the "Address priveted ".
