Public bug reported: I got a Intel I217-V integrated on the motherboard, it is an Ethernet NIC.
$ lspci 00:19.0 Ethernet controller: Intel Corporation Ethernet Connection I217-V (rev 04) Before this worked good, but yesterday it stopped working after restarting the computer from Windows 10. I suspect there might have been some Windows update maybe. It seems to work again after I went into the Device Manager in Windows and turned off power management settings. Under the "Power Management" tab, I unchecked the checkbox option "Allow the computer to turn off this device to save power". Under the "Advanced" tab, I selected the "Enable PME" option and changed it from "Enabled" to "Disabled".
