How do I disable the Private (random) Wi-Fi addresses on my iPhone?

How to turn off Private Wi-Fi address in iPhone iOS 14 and later

1. Open the Settings app, then tap on Wi-Fi. 
2. Tap on the information button  next to your Plume network name.                                                     
3. Tap on the Private Address toggle to turn it off, a message will pop up to rejoin the network.             
4. The iPhone will briefly disconnect and then reconnect using the original hardware Wi-Fi address.   

Once connected back to your Plume network using the original Wi-Fi address, any of the previously personalized device or employee level features such as Online protection, Content access controls, shared devices, will be applied to the device again.        

Note: These settings will only be saved for your Plume network and your iOS device will continue to protect your privacy by using a Private Wi-Fi address when connecting to other networks.
