Trying to set up a new build on an ASUS NUC14MNK with Unraid 7.1.2

In the middle of boot sequence, I get the error message "Device 'eth0' does not exist". Finishes boot and able to log in, but no internet on ethernet or wi-fi.

I did try the various fixes suggested in this thread: https://forums.unraid.net/topic/124156-no-network-after-6102/ but nothing seemed to work. (Tried the tg3.conf file, disabling Intel VT-d in BIOS, and adding intel_iommu=off to my syslinux.cfg)

Diagnostics attached.

NIC is not supported by the stock Linux driver, you can try the Realtek plugin, that should support it, you will need a temp NIC to install it, like a WI-FI dongle, or just boot the flash drive in an older PC to install it.

Sorry, which Realtek drivers should I try? I see 8125, 8126, 8157, and 8168 options, but nothing for 8169. I also found support threads for people having issues with the default 8169 driver, so I guess there was one but there isn't anymore?

Believe it uses the RTL8125BG-CG - see: https://www.asus.com/us/displays-desktops/nucs/nuc-mini-pcs/asus-nuc-14-essential/techspec/

Yep, Realtek 8125

Thanks, guys! Got it online.
