Asus K52F missing UUID and mac address

[gabiz_ro]

Somehow this laptop lost that.
mac address and UUID are all just FF
BIOS is AMI. and network card is JMicron 25x

Since that wired network isn't working but if manually put mac address then work fine.
That's a temporary solution since isn't mine and after OS reinstall problem appear again.

I have tried
-EEMAC but was error smbprom not found,I think LAN controller doesn't have eeprom wired and is programmed by BIOS.
-DMI236 /o 1macaddress is not working.
-dmiedit
-afudos /Mmacadress complain about write protect.

Is there any way or other tools that can rewrite mac address.
