Ubuntu 22.04.3, Kernel 6.5.0-14-generic and RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller

  • 772

This morning 2 of my Ubuntu installs that are both 22.04.3 LTS running HWE upgraded to Kernel 6.5.0-14-generic. After rebooting both systems the network cards that are RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller did not come up. Booting to the older 6.2.0-39-generic Kernel the network card works just fine. Upon trying to reinstall the r8168-dkms driver which installs the driver version 8.049.02 fails. And running sudo lshw -C network is showing the card as UNCLAIMED.

P.S. I will not use the r8169 driver for my r8168 chipset as it will work OK in the beginning but after a little bit will give unpredictable behavior, some to the point of needing a hard reboot of my system to bring the interface back up.

    NOTE: I had noticed that if I had booted into Windows 10 that when I booted back to Ubuntu without a hard power cycle that the NIC would not work correctly. This was actually due to the driver version in Windows creating this problem for some reason. To fix it I had booted back into Windows and downloaded and installed the 10.69 driver from Realtek themselves. Now rebooting from Windows back into Ubuntu there is no issues.

    Driver Installation:

    The 8.049.02 driver appears to be incompatible with the 6.5.0-14-generic Kernel and DKMS cannot install the driver.

    Boot back to a working Kernel and download the Realtek 8.052.01 driver from here.

    After downloading the driver, go ahead and extract the files.

    tar xvf r8168-8.052.01.tar.bz2

    Enter the new directory that was created.

    cd r8168-8.052.01/src

    Create a new Kernel source directory for the driver.

    sudo mkdir /usr/src/r8168-8.052.01

    And copy all the files to the new directory.

    sudo cp -v * /usr/src/r8168-8.052.01/

    Create a new dkms.conf file for the driver.

    sudo nano /usr/src/r8168-8.052.01/dkms.conf

    and now add the following content to the file.

    PACKAGE_NAME="r8168"
PACKAGE_VERSION="8.052.01"
BUILT_MODULE_NAME[0]="$PACKAGE_NAME"
DEST_MODULE_LOCATION[0]="/updates/dkms"
AUTOINSTALL="YES"
REMAKE_INITRD="YES"

    Save the file and run the next lines to build and install the driver.

    sudo dkms add -m r8168 -v 8.052.01
sudo dkms build -m r8168 -v 8.052.01 -k 6.5.0-14-generic
sudo dkms install -m r8168 -v 8.052.01 -k 6.5.0-14-generic

    Now when you check the dkms status you should see the new driver installed into the kernel.

    $ dkms status
r8168/8.049.02, 5.15.0-91-generic, x86_64: installed
r8168/8.049.02, 6.2.0-39-generic, x86_64: installed
r8168/8.052.01, 6.5.0-14-generic, x86_64: installed

    Reboot the system and boot into the newest Kernel and the RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller should come up fine.

  2. Check if r8169, which is builtin in kernel, works well now with your controller. Purging r8168-dkms worked for me
