This bug has nothing to do with linux-firmware, changing to affect linux. I don't know that I'd say the "wrong" driver is being selected here. It sounds like there is an in-kernel driver that supports the NIC, but does not seem to support it at full speed. So there is a kernel issue here, but you're likely to make more headway reporting it to the upstream driver maintainer. We can help you do that if you like.
Your complaint seems to be that you weren't offered the dkms driver by default. I know there used to be a system that offered extra drivers during installation. I assume it's still there, but I'm struggling to remember what it was named, and I don't know what the procedure is for updating it. ** Package changed: linux-firmware (Ubuntu) => linux (Ubuntu) -- 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/1782608 Title: Fresh Ubuntu 18.04 install uses wrong Realtek wired network driver. Status in linux package in Ubuntu: Incomplete Bug description: Hi there, Installing Ubuntu 18.04 on my newish laptop which contains a Realtek 8168 NIC seems to use the r8169 driver by default, and should use the r8168 in order to work properly. To fix, I removed or blocked the 8169 driver, installed the 8168 driver and then reconfigured NetworkManager - which was quite difficult for a new user like me. I've included details from my system since I addressed the issue yesterday. Please let me know if there's anything I can do to help more. ~$ lsb_release -rd Description: Ubuntu 18.04 LTS Release: 18.04 ~$ apt-cache policy r8168-dkms r8168-dkms: Installed: 8.045.08-2 Candidate: 8.045.08-2 Version table: *** 8.045.08-2 500 500 http://ca.archive.ubuntu.com/ubuntu bionic/universe amd64 Packages 500 http://ca.archive.ubuntu.com/ubuntu bionic/universe i386 Packages 100 /var/lib/dpkg/status ~$ neofetch OS: Ubuntu 18.04 LTS x86_64 Host: Aspire A515-51G V1.10 Kernel: 4.15.0-23-generic Uptime: 30 mins Packages: 2124 Shell: bash 4.4.19 Resolution: 1920x1080 Terminal: gnome-terminal CPU: Intel i5-8250U (8) @ 3.400GHz GPU: Intel UHD Graphics 620 GPU: NVIDIA GeForce MX150 Memory: 3457MiB / 7725MiB ~$ sudo lshw -c network *-network description: Ethernet interface product: RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller vendor: Realtek Semiconductor Co., Ltd. physical id: 0.1 bus info: pci@0000:02:00.1 logical name: enp2s0f1 version: 12 serial: 98:29:a6:40:b5:f1 size: 10Mbit/s capacity: 1Gbit/s width: 64 bits clock: 33MHz capabilities: pm msi pciexpress msix vpd bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=r8168 driverversion=8.045.08-NAPI duplex=half latency=0 link=no multicast=yes port=twisted pair speed=10Mbit/s resources: irq:128 ioport:3000(size=256) memory:a4204000-a4204fff memory:a4200000-a4203fff ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: linux-firmware 1.173.1 ProcVersionSignature: Ubuntu 4.15.0-23.25-generic 4.15.18 Uname: Linux 4.15.0-23-generic x86_64 NonfreeKernelModules: kpatch_livepatch_Ubuntu_4_15_0_23_25_generic_40 ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 CurrentDesktop: communitheme:ubuntu:GNOME Date: Thu Jul 19 09:56:08 2018 Dependencies: InstallationDate: Installed on 2018-07-16 (2 days ago) InstallationMedia: Ubuntu 18.04 LTS "Bionic Beaver" - Release amd64 (20180426) PackageArchitecture: all SourcePackage: linux-firmware UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1782608/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
