Comment 0 for bug 1687262

This is a regression.

Upon upgrading 16.04 -> 16.10. Wired connection provided by "RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller" has stopped working.

Quickly looked around for possible solution, and decided to go on with upgrade to 17.04, since it was my initial upgrade target anyway, and wireless on the system continued to function. So, ended up in this situation: running 17.04, wireless adapter is working, while wired does not work any more.

Extra observation: I've also tried live session from USB based on 17.04 ISO-image, wired network adapter just works in the live session.

Conclusion: it is a software issue.
