** Also affects: linux (Ubuntu)
Importance: Undecided
Status: New
** Tags added: apport-collected bionic
** Description changed:
From the Bionic archive (universe) the r8168-dkms driver is supposed to
get better performance compared to the kernel builin r8169 one, with has
degraded speed mainly due to MTU 576 and only using 100 Mbits/s.
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.
