Network problem on dual boot - Centos and Windows Server 2012R2

Hi,
On few Lab's PC i have installed Windows Server 2012R2 and Centos8.4
here is grub's menu entry for Windows:

Quote:

menuentry Windows --class windows --class os { insmod chain insmod ntfs set root=(hd0,msdos1) chainloader +1 boot }

Windows loads, but with network issues - integrated network card is not working using static ip adress and via DHCP too. Tested Connectivity using USB Network Adapter - works without problems. Integrated NIC works on Centos, also worked on windows before installing Centos and loading via grub.

What to to to solve this problem?
Thanks :)

p.s. sysem works in legacy (BIOS) mode.
