i'm getting error network UNCLAIMED, and i see through the forums that it states the drivers. well, my kernel is 5.3.0-20-generic, and it states when i try to install the drivers, its the latest...and its not working. do i need to downgrade to the prior version of the drivers or wait till the create it for this kernel? funny thing is my wireless interface is working...any help in the right directions, thanks.

$ sudo lshw -C network

You don't need r8168-dkms with new kernels.

Remove it by sudo apt purge r8168-dkms and the adapter will be managed by the kernel in-tree module.

I had the same problem with my System76 Gazelle. I don't know why, but running:

sudo modprobe r8168

caused it to work.

It gave me this error when I ran the command:

modprobe: FATAL: Module r8168 not found in directory /lib/modules/5.3.0-7625-generic

but it turned on.

I haven't got high enough rep to comment, but I had this exact problem. I solved it by downloading the latest Realtek 8168 driver and installing. I don't think Realtek provide the drivers any more, but they have kindly been archived here: https://github.com/mtorromeo/r8168/releases

  1. sudo apt-get install build-essential linux-headers-$(uname -r)

  2. sudo sh -c 'echo blacklist r8169 >> /etc/modprobe.d/blacklist.conf'

  3. Download latest tar.gz from https://github.com/mtorromeo/r8168/releases

  4. tar xfvz r8168-X.XXX.XX.tar.gz (replace XXs with name of file you downloaded)

  5. cd r8168-8.XXX.XX

  6. sudo ./autorun.sh

Hope that helps

    Hi @qualia, after you do this how do you actually get the error (UNCLAIMED) to go away? Is there anything else? I followed your instructions and rebooting did not seem to fix. – ComputerScientist Sep 25 '20 at 14:49

resolution at the time of incident on a system76 lemur6, which was back 11-7-19, so you would need to make sure to get the latest driver:

grab a copy of the latest r8168 driver (or download it via another computer and put it on USB storage)

wget http://mirrors.edge.kernel.org/ubuntu/pool/universe/r/r8168/r8168-dkms_8.047.02-1_all.deb Install that driver (will automatically regenerate initramfs kernel image with integrated driver)

dpkg -i r8168-dkms_8.047.02-1_all.deb or use gdebi package installer (log below)

  • Remove elder driver, blacklist it, and use newer one

$rmmod r8169

$echo "blacklist r8169" > /etc/modprobe.d/blacklist.conf

$modprobe r8168`

(and try if everything works after a fresh boot)
