-This Wiki page isn't complete yet.
-If you know how to disable MAC randomization for operating systems which are not listed here, please tell us how via <helpdesk@fem.tu-ilmenau.de> so we can improve this wiki page.

-===== What is the problem? =====
-MAC randomization is a new technology used in many mobile devices to prevent you from being tracked by your MAC address when searching for Wi-Fi networks.
-Hence, the feature contributes to privacy and protection against tracing.
-A MAC address is randomly determined and used when searching for and connecting to networks.
-However, in FeM-Net, devices are identified by their MAC address.
-So, if MAC randomization is activated, the device tries to connect via a MAC address that does not match the one in our database, which is why the connection fails.
-You can recognize MAC randomization when you see a different MAC address on our [[https://myinfo.fem.tu-ilmenau.de|MyInfo page]] in the FeM_Welcome Wi-Fi than the one in the settings of the affected device, for example.
-===== How do I disable that? =====
-This varies for each operating system, but there is usually the option of deactivating the feature only for individual Wi-Fi networks, which ensures privacy.
-==== Android ====
-Android supports MAC randomization from Android 10.
-This feature is therefore not available on older systems.
-For deactivation:
-  * Open settings > Network & Internet > Wi-Fi
-  * For our Wi-Fi networks (e.g. „FeM.PSK“ and „FeM.1X“) open the settings by pressing and holding down the respective Wi-Fi network > Modify network
-  * In the advanced options, there should now be a corresponding privacy setting that allows to switch off MAC randomization.
-==== iOS ====
-Apple Support offers a guide for iOS 14: https://support.apple.com/en-us/HT211227
-==== Windows ====
-In the Wi-Fi settings there is a section called "Random hardware addresses".
-The switch "Use random hardware addresses" must be deactivated.
-This should deactivate MAC randomization for Wi-Fi.
