When you reboot from Windows, i.e. network is unusable, does lspci show the NIC?
It might be possible that Windows powers off the NIC and motherboard does not power it on and therefore the NIC is no visible to Linux. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1904895 Title: Network does not work after restart from Windows 10 Status in linux package in Ubuntu: Confirmed Bug description: 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".
