Yesterday i found out that Zorin OS switched my Nvidia GPU Driver to the "CPU driver" i noticed it because of bad performance in games and etc... , i tried installing a Nvidia GPU driver again and it completely broke everything so i had to make everything like a Terminal gui somehow idk how i did it but it worked and what fixed it is sudo purge nvidia* or something like that after that my ethernet and wifi didnt work any more.
Hello and welcome,
Do you have a dual boot ?
If no go to your Bios and disable secure boot, if yes go in windows power management and disable fast boot.
We will also see if you are on xorg or wayland for this do this in terminal
echo $XDG_SESSION_TYPE

Welcome to the Forum!
Are Secure Boot and Fast Boot in BIOS disabled? If Windows is still installed: Is Fast Start-Up in Windows disabled?
Did You take a Look at the ''Additional Drivers'' Tab in Software & Updates if there is a Driver for Your Wifi/Bluetooth offered? Could you post the Output of the Commands sudo lshw -C network and rfkill list please?
