[SOLVED] New version of NetworkManager breaks my Ethernet connectivity

I have recently updated the networkmanager package to version 1.46.0-1 and my Ethernet connectivity immediately stopped working after the reboot.
By default, I have a DHCP connection that stopped working completely. I also tested a static IP connection that did not work either.

After downgrading the networkmanager package to the previous version from the pacman cache (1.44.2-3) the Ethernet network started working again perfectly.

Edit:
I just found the related issue in the NetworkManager GitLab project:
https://gitlab.freedesktop.org/NetworkM … ssues/1485

and in the Arch Linux networkmanager package project:
https://gitlab.archlinux.org/archlinux/ … -/issues/2

Re: [SOLVED] New version of NetworkManager breaks my Ethernet connectivity

I have the same issue, this fixed it for me without downgrading:

nmcli connection modify "Wired connection 1" ipv4.dad-timeout 0

Of course replacing the name of the connection with the actual name.
