Although my ethernet card worked, I had very bad latency and speed. I looked up the hardware and I found a driver. Having run its script makes the hardware work correctly. It loads the module by calling modprobe. However, I have to do this after every boot. How can I permanently install this module?

Just add the module to /etc/modules to make sure it's autoloaded at boot. Use the following command

echo r8168 | sudo tee -a /etc/modules

or edit /etc/modules with your favorite text editor and add r8168 to the bottom.

After adding the module, the initial ramdisk should be updated with this driver, run:

sudo update-initramfs -u
