No Xedoes, I do not think that changing kernel would help, I just pointed out a difference with my setup.
Can you boot on a Manjaro live media with your ethernet connected ? If that works, the problem is in your installation on disk. If ethernet still does not work, you could try another distro’s live media and check ethernet. If that still does not work, the problem could be BIOS setup or broken hardware.
Okay got the fix for my laptop the problem was in BIOS settings in bios we need option called switching between wifi/lan to be turn on and lan controller as well now eth0 is recognizable.
Hope it will help others!
