I haven't been able to solve it on my end. I wonder if it's a hardware issue? Interesting to see that others are having the same issue.
May I double confirm all of you connect the10GB ethernet port directly on the motherboard?
Which status does the 10GB ethernet port indication show? activity link LED and speed LED both are off?
Does it disconnect from the internet on bios 1304 with bios all default settings and Marvell Ethernet connection Driver V188.8.131.52?
