SO I tried the manual install on my first x86 system which I do have SSH access. I figured install the drivers on that one, image the system and restore it on the new H2+.
Manual installation
In a console window:
...$ cd ~/Downloads
...$ wget master.zip -O realtek-8125-dkms.zip
...$ unzip realtek-r8125-dkms-master.zip
...$ cd realtek-r8125-dkms-master/
...$ sudo ./autorun.shIf you do not want to use wget use whatever command your prefer (i.e git clone).
After executing these commands, you should have the NIC available for configuration using the Network Manager or equivalent.
If you want to know what the autorun.sh does before executing it, just open it in your favorite text editor (vim, pluma, etc.)
You can also find the REALTEK_README.txt into the folder providing additional information.
I guess you have to have the hardware in the system in order for it to install the drivers. Ended up with an error on line 30 of the autorun.sh script.
Anyone else able to help get this working for the meantime? I've looked into compiling my own but that's about 100 levels up from what I am able to do with linux at the moment. I couldn't figure out how to get the latest kernel. I ran a docker container from an Ubuntu image in the DHub repository. Turned out is was Kernel 3.x. I'm out of my depths here.
