I have a small problem with my UNRAID-Server. I replaced the hardware of the hostsystem. Everything expect the NIC works fine.  Mainboard is an Asus TUF GAMING B550-PLUS with a Realtek RTL8125B 2.5Gb Ethernet-NIC. If I boot just with this NIC I get a random private IP. I have deleted from the boot-Partition the network.cfg and edited this file. With an USB-NIC the network works almost fine but seems to stops working after a random time.   Any Ideas what to do? I did not find any info
