Linux Mint / Ubuntu 20 Intel I219 NIC disconnects
If you are using the stock 5.4 kernel this is normal but I can confirm it is fixed in newer 5.8 kernels.
To fix it just install the 5.8 kernel and reboot:
sudo apt install linux-headers-5.8.0-64-generic linux-modules-extra-5.8.0-64-generic linux-image-5.8.0-64-generic
