I tried to install Ubuntu on my new laptop (Skikk Niflheim 17 II RTX 4060), but the installation failed because no wired connection can be made. I tried to install Ubuntu 24.04, Kubuntu 24.04, Ubuntu 22.04.2. All gave the same problem.
I tried to solve the problem with the help of the solution (https://serverfault.com/questions/1150097/no-wired-connections-in-ubuntu). But that did not help because when I boot a livecd with Ubuntu 22.04.2 lspci showed "Network controller: Intel Corporation Device 272b (rev 1a)". In the solution Device X772 was used.
What should I do to get my wired network connection working?
