Installing that driver onto a 4.13.13 based kernel goes as expected, but after rebooting there is no network at all, ping fails. Blacklisting r8169 or not makes no difference. An issue is opened on https://github.com/mtorromeo/r8168/issues/9 So that driver is not usable actually with the proposed kernels from the recent ubuntu releases; maybe the driver description could point that limitation, if a bypass is not found. About the kernel itself, maybe the builtin r8169 driver could deliver better performance , for example setting MTU to >=1492 at least. --- ApportVersion: 2.20.8-0ubuntu3 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: oem 1288 F.... pulseaudio CurrentDesktop: GNOME DistroRelease: Ubuntu 18.04 EcryptfsInUse: Yes HibernationDevice: RESUME=UUID=06a0e343-7443-402b-a607-1fe53f3c1ac3 IwConfig: enp2s0 no wireless extensions. lo no wireless extensions.
