Finally got around to upgrading to 18.04. I installed a fresh hard drive, installed Kubuntu 18.04.1, and 8169 driver was chosen.
My ethernet would not negotiate anything higher than 100MB-HALF. Installed the r8168-dkms driver, rebooted, and immediately got 1GB-FULL. r8169 is not the correct driver for "RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller" -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1782608 Title: Fresh Ubuntu 18.04 install uses wrong Realtek wired network driver.
