Networking yoyo (down & up)

Every few minutes I get in the journal + a notification in the system tray:

The config is: STATIC IP, method manual in the network manager, not DHCP.

What am I missing?

Here’s my inxi for the network.

I’ve been trying but…

Here’s my eth0.nmconnection


**$ **sudo cat /etc/NetworkManager/system-connections/eth0.nmconnection

Show output of “nmcli connection show | cat”.

Did you change connection properties from automatic to manual IP address using NM GUI or CLI while connection was active? Try “nmcli device reapply eth0”.

25 minutes ago, I did:


sudo nmcli device reapply eth0

and I get:

Thanks but that’s not helping, it’s the same.

The carrier goes up & down, but it’s not a hardware problem because when I boot into my live debian 11.3 bullseye, no problem at all. So somewhere, there’s some setting in leap that makes the eth0 a “yoyo”

arvidjaar · June 20, 2022, 6:44am

Same what? First you show log full of DHCP requests and connection definition with static address. Now you show log without DHCP requests. So it is not “the same”.

May be next time you should start with explaining your actual problem and not expect others to read your mind.

The carrier goes up & down

And what is the actual problem besides these logs? You never explained it.

elfroggio · June 20, 2022, 4:21pm

I have solved the problem. It’s TLP. Black listing the USB ethernet in TLP and now it works. This came from the manjaro forum which in turn came from an ubuntu forum.

BTW1, the exact problem was the carrier going up and down, so I only displayed the journal relating to eth0.

BTW2, how do I mark the thread as solved?

Thanks
