Greetings.
I’ve never had a problem with Manjaro for almost two years, but ethernet. This ethernet issue would appear once in a while and I have no idea what it wants. Don’t know for sure why it showed up this time(I guess after system update) and why it disappeared in the past.
I prefer to use wired ethernet connection on my laptop Hp probook 430 g5. No issues with wi-fi though.
Some outputs of commands from wiki.
