I migrated my server (6.12.4) to a new build after which I am getting “Device eth0 does not exist “ and unable to connect to network. 

 

It is an onboard 2.5gb on Gigabyte Z790 D, which is recognized both in the BIOS and under System Devices. 

 

So far I have upgraded BIOS to latest, deleted network.cfg, switched from static to DHCP, tried different ethernet cables and ports, turned off VT-d in BIOS.

 

After scouring the forums I am now wondering if this is associated with some issues with RealTek RTL815 drivers.

I am still a bit of a noob, so I wouldn’t know how to install this driver-plugin without internet, or even if it is the right solution in the first place, so would massively appreciate any assistance or support to help resolve this.

 

I have attached some screenshots and diagnostics from this morning.

The r8169 driver is being blacklisted, delete /config/modprobe.d/r8169.conf from the flash drive and reboot.

Thanks, @JorgeB - that seems to have done the trick and I am now back up and running on the network.

 

However, it appears that r8169.conf re-installed itself, so after my second reboot i got the same issue again and had to delete the file again. Is there a way I can prevent that driver from being installed?

You could try deleting the "unraid-r8168" plugin and rebooting in case that is doing it.
