Have a look at this:

They have installed the r8169-dkms driver (we have it in chaotic) and blacklisted the r8169 driver.
The one you are currently using. You can do that with
- create a file
/etc/modprobe.d/r8169.conf - Open that file as a root user (use sudo and your fav. terminal editor)
- Enter the following, save and exit
blacklist r8169
And set the following kernel parameters (you can append these to your parameters using garuda boot options app)
r8168.aspm=0 r8168.eee_enable=0 pcie_aspm=off
Then reboot and see if this helps?
