Since today I have strange issues with my ethernet connection on Manjaro.
To make sure the issue was not on my connection side, I can confirm the network connects instantly and works well under Windows, but when I reboot on Manjaro it just fails and fails and so on… after rebooting a lot and restarting the router and deleting/recreating the connection in Network, in short insisting A LOT, then at some point it connects after a reboot or after failing a lot.
Here is my inxi:

So the issue is that the NetworkManager fails to connect to my router, with error popup saying (translated) Ethernet connection disabled
followed instantly by the IP configuration was unavailable
I tried to disable NetworkManager and switch for DHCPCD but when it fails with NetworkManager, it also doesn’t work with DHCPCD. So I’m back with NetworkManager for now.
So right now I am connected it works good, like before, but for the next time, how would be the proper way to troubleshoot, what info would be relevant to look at, what logs and which specific keywords in these logs would be the best to try to find the issue?
If anyone can give some advices, I’m all ears because I’m lost currently and when it happens I’m just not fixing anything, I think it just works again by itself for unknown reason.
