The Android operating system is delivered with a random MAC address. 

What does it mean?

For security reasons, the device no longer displays a fixed MAC address. For each network contact the device creates a random MAC address.

How to disable this function?

When setting up for the first time or adding a new network, the following screen appears:

Open <Advanced options>

Open <Privacy>

Select <Use device MAC>

Your device now works with a fixed MAC address.
