Android cannot connect to company WIFI which requires MAC address registration

 Issue: 

Company need device WIFI MAC address to allow WIFI connection. 

Android WIFI MAC is registered to company's database, but still connect to company WIFI. 


Cause:

In Android 10, MAC randomization is enabled by default for client mode, SoftAp, and Wi-Fi Direct. 

Though MAC address is registered, but when connecting to WIFI, Android is using a randomized MAC address instead of the WIFI network card's real MAC address (registered in database). 



Solution:

Turn off "randomized MAC" and use device MAC. 

Settings -> network & Internet -> Internet -> select the Wifi network SSID and switch to "use device MAC" under "Privacy".
