I recently upgraded to 22.04. Wifi works a charm, ethernet does not.

Here is the result of network-test

Here is the result of lshw -c network

And here is the result of ifconfig -a

        device interrupt 16  memory 0x91200000-91220000

Clearly, the wired connection gets no IP assigned (I tried assigning one manually, but it still receives no packets). However, I guess this would usually be expected to work "out of the box". Any hints as to what information may help/what I should try to fix this much appreciated.

For completeness's sake:

  • Hey i'm facing the same issue, my adapter is: "RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller". Did you manage to fix it. – Yordan Pavlov Jun 22 '22 at 08:12
  • I have the same issue as well – zpontikas Oct 21 '22 at 20:26
  • I had a similar problem (updated Kubuntu, restarted, and ethernet didn't work while WiFi did and while #2 it worked fine when I dualbooted into Windows10).

    It was caused by the "generally safe" (!!) apt autoremove. I pulled the removed packages by grep remove /var/log/dpkg.log and reinstalled most of them, save for linux-headers* and such. Rebooted the system and all was good. #Kubuntu2204 #DontTrustAutoremove

I am happy to report that I got this to work. For me the package netplan.io was missing. This was causing the yaml /etc/netplan/01-network-manager-all.yaml to not be applied. If this yaml file is missing for you have a look at this answer for what its contents should be.

  • why was it missing and how did you get to this state? i did a simple ubuntu-driver autoinstall and it bricked me – mathtick Jul 12 '22 at 15:28
  • I am not sure why the netplan.io package was missing originally in my case. It must have been removed along with other packages. – Yordan Pavlov Aug 16 '22 at 14:13
