[linux57] LAN Ethernet interface call connection after upgrade to linux57 BUT there is no cable here

linux57 "stable"

Issue

LAN Ethernet call connection when cable is not connected.

02:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller [10ec:8168] (rev 15)

Under 5.6.x all is fine and LAN do not freak out like this.
Solution?

Kernel 5.7 final still has broken networking

Hi After its final release, Kernel 5.7 (Manajaro Unstable) still has no working networking for me. I can also see (ip a), that I have an eth0 AND enp5s0 device - up to kernel 5.6 eth0 got renamed during boot to enp5s0 - the 5.7 bootlog also shows, that this happens and it shows, that NetworkManager tries to connect to eth1 which doesn't exist - my entries in /etc/NetworkManager/system-connections/ have no explicit mentioning to use either ethX or enpXs0. Any Ideas?

just wait few more point release to hope to have a fix. and stay on 5.6 till then.. or 5.4

thank you

For KDE, deleting both connections work after creating a new one. For Cinnamon and Gnome, network manager displays them permanently. For the one that does not exist, disable connect automatically is a quick fix.

Otherwise, L57 runs Ok and this bug is present in Manjaro only.

Simply restricting the connection to the correct device should work as well on KDE.

indeed, that worked for me.
