LAN Mac Address N/A

[Soumil]

Hi Everyone,

I have a motherboard Gigabyte B550M DS3H and I updated my Bios and now my ethernet port is not working. I digged in regarding this issue. I found that my LAN mac address is showing NA in Bios. 
I tried reflashing bios it still didn’t work. Can anyone please help me. 
Thanks in advance:)

Looks like the LAN chip might have given out, i would RMA if it still has warranty. A CMOS reset might be a longshot but still worth a try, or you can get an USB/PCIe ethernet/wifi card.
