Gigabit Ethernet port not working debian 10

erasedhammer · September 2020

I have loaded debian 10 on my up board and the link does not want to negotiate. Autoselect on both ends and the up board just defaults to amber LED. If I force selection to 100baset full duplex the up board LED goes green, but my switch goes amber.

I figure this is a driver issue with the realtek 8111 nic. Can't seem to figure out how to install the driver though.

Does anyone know how to fix this without internet?

Debian by default does not include proprietary drivers and it might have problems with some peripherals, have you tried to install the version with the additional drivers/firmwares?

I've tried several times with installing the r8168 driver. Unfortunately the autorun script that these usually have break. So far I have encountered "make command not found" after painfully installing make package and its dependencies manually, it still breaks saying its missing dkms package. Tried installing that manually and it did not work (had almost 30 separate deb files in /var/cache/apt/archives and still no go.

Installing these packages manually is an absolute pain and just doesnt end up working most of the time. I was hoping to find some other way to get this nic working.

I just received my second up board, and installed the debian rtl_nic/rtl8168g-2.fw firmware.
ethernet still NOT working
ip link says its up.
arp appears to be working as the router at the other end has it in its arp cache. But anything layer 3 and up is just broken.

Have you tried to install Debian 10 from the link above?
That image includes the necessary nonfree firmware and configuration also for the realtek and it works out of the box.

If you want to try from your already installed system, you do not need to compile it from source.
Try downloading and installing this package from the debian repository: https://packages.debian.org/buster/firmware-realtek

dpkg -i nameofthepackage.deb
