EDIT: after further inspection it seems more like a cabling issue, not a driver issue. I found the following in the kernel log: `dmesg | grep r8169` (r8169 is the driver used by Realtek RTL8111): [ 41.922626] Generic FE-GE Realtek PHY r8169-0-500:00: Downshift occurred from negotiated speed 1Gbps to actual speed 100Mbps, check cabling! [ 41.922658] r8169 0000:05:00.0 eth0: Link is Up - 100Mbps/Full (downshifted) - flow control rx/tx Hope someone else finds this useful. As far as I can tell, the r8169 driver and RTL8111 works fine on UnRAID – if you also can't get gigabit check your kernel log and cables!

Hi, I've built a new UnRAID NAS with the Asus A320I-K motherboard with the Realtek 8111 chip. Unfortunately, I can't get the Ethernet port to negotiate gigabit speeds no matter what I do – it keeps going back to 100 Mbps. My switch definitely supports Gigabit, and I've swapped several Cat5e cables to rule out a problem with the connection.

[AMD] FCH SATA Controller [AHCI mode] (rev 81) I did read one report about the Realtek 8111 driver potentially being faulty and not allowing for gigabit speeds. Unfortunately, I've already built this NAS inside an ITX case and do not have a spare port to put in another Ethernet card with better compatibility. Is there some other issue at play here or would I have to wait until the drivers improve for the 8111?

I ran into this problem and you can fix it by setting the extra parameter option like so: (If you do not see this option you will have to toggle Advanced View on the top right.)
