I have an i5 machine with a ASRock Z590 Pro 4 motherboard. ASRock's website says this board has a Dragon RTL8125BG. I believe this is based on RealTek, but I'm not positive. Since updating to the latest TrueNAS Core, it no longer sees the network interface. I have lights on both my motherboard as well as the switch, but my router doesn't see it. I've tried downloading earlier versions of TrueNAS, and they suddenly no longer work either. I've been playing with this for a month and can't figure it out. If anyone has any ideas, I would really appreciate hearing them.
