No ethernet light on Asus Prime z270-a board

[tvojm100]

Hi all, 

 

I have an Unraid setup with the above mobo. I was trying to access the GUI via web interface, but could not do so. Logged on to the GUI directly and it says 'interface ethernet 0 is down'. 

 

Checked the network port on the mobo and there are no lights to be seen. 

 

Have tried basic elimination - change network cables, switch port, connecting same port to a laptop (which works fine). 

 

I am not at all familiar with the Linux OS. How would I go diagnosing the issue? Cannot see anything in the BIOS of the mobo. 

 

Note. The Unraid setup was working fine yesterday. No configuration/updates have been made. 

 

Thanks.

If no light ever pops up, maybe the port itself is dead 

 

But, you can always post your diagnostics here

I have just put Ubuntu on USB and ran it on the same machine as Unraid and Ubuntu is connected to the network and is able to access the Internet and other internal web GUI interfaces. Lights on the network port are present. 

 

Thought I'd plug back Unraid, but I get the same thing - no Web access or port lights.

Seems as though the MAC addresses had got swapped around. Changed them back and now have access again.
