NIC not running at 1000BaseT(Gb)


Recommended Posts

This is the re-occurrence of an issue I had earlier that was fixed, or so I thought.



I executed "ethtool eth0" on my unraid system and I'm seeing "Speed: 100Mb/s" which is what I do not expect.


I have Gigabit in the server going to a Gigabit switch. I also tried forcing it by

"ethtool -s eth0 speed 1000 duplex full autoneg off


Output from ethtool:

~# ethtool eth0
