Go to your Bios and disable secure boot and fastboot

I it doesn't change anything try this fix

Step-by-Step Fix

Note: This “fix” method requires that Secure Boot be turned off/disabled, else Zorin will not load the “foreign”/unsigned driver.

  1. Download Driver:
  1. Extract and install:
cd ~/Downloads
unzip r8125-9.016.01.tar.bz2
cd r8125-9.016.01
sudo ./autorun.sh

Ignore any warnings about System.map or BTF unless they stop the install.

  1. Reboot the system:
sudo reboot
  1. Check that the driver version loaded is correct:
sudo ethtool -i enp1s0

Look for this line:

driver: r8125
version: 9.014.01-NAPI  # Or later, depending on Realtek release

Note: Despite the Realtek site listing version 9.016.01, the compiled driver may report as 9.014.01. This appears to be normal in Realtek’s source packaging.

To confirm which file is being used:

sudo modinfo r8125 | grep -i filename

It should show:

filename: /lib/modules/$(uname -r)/kernel/drivers/net/ethernet/realtek/r8125.ko.zst
and/or
filename: /lib/modules/$(uname -r)/kernel/drivers/net/ethernet/realtek/r8125.ko

If all is well, your Ethernet port should now work normally, and DHCP should succeed.
