Hi, recently I’ve installed Manjaro (KDE plasma) and few minute later I’ve found the issue with network, randomly disconnect and reconnect and do this in loop for a while.
I’ve thought the problem was the cable but on Windows and debian running on VM is working fine. I’ve read some thread with the same issue caused by the tlp and tried to remove it but nothing changed.
Here there’s the journalctl -fu NetworkManager during one disconnection and reconnection:
