When trying to install the NVIDIA driver through "software and updates"
When restarting, not only did it not install the update but it also transferred the graphics to llvmpipe (LLVM 12.0.0, 256bits) and I can't access the wired internet (in this case I don't have wifi because I'm directly on the PC)
If you are using a VPN, that is the most likely cause of the net issues. I certainly agree that the Nvidia drivers on their own cannot and will not affect the internet.
