Does anyone know when the random M.A.C. address changes.  For example if you go to the same public WIFI should it change on every connection or every WIFI site.?

Hi, It is every twenty-four hours. This setting is network-specific.

Your answer is not correct. I tested it at 2 public WIFI sites and after close to 48 after disconnecting from the 2 public wifi's the original random Mac address was maintained.

Hi Samsungtwo, I also mentioned that the setting is network-specific.

Hi, Randomization of the MAC address can happen at timed intervals or whenever the device probes a new SSID.

The time interval you presented of 24 hours did not change the MAC address, so should I expect the MAC address to remain the same with the vendors BSSID ? Can that value be cleared? The address should be changed anytime a user connects otherwise a vendor can determine, with time who is using the phone.

Hi, Could you please confirm if the Mac address type under your Network is Randomised MAC or Phone Mac?

Note that I tried clearing the network using managed networks.

It is randomized MAC for all networks. Accept my home network.
