On my first OS when I changed the device number the mac address would change. Ver 2.1 , My new ones Ver. 2.2 the mac id is not changing. Also I am unable to find where I can name my device so they are all showing up as os1. Am I missing something or is this normal. It looks as if the newer hardware now has a fixed mac address which is ok, just wanted to make sure this is the case.
You are correct, newer devices have a hardware chip that defines a unique MAC address making the device ID pointless (hence no change after changing it).
We will be updating the next firmware to remove this option from devices that have the hardware MAC defined.
