[Solved] eno1 no carrier

Hi there,

I have trouble to configure my ethernet link. It worked well a week ago. I think it appears after systemd update (but i am not sure...) :
- libsystemd (234.11-3 -> 234.11-4)
- systemd (234.11-3 -> 234.11-4)
- linux (4.12.3-1 -> 4.12.4-1)

ip link show eno1
2: eno1: <NO-CARRIER,BROADCAST,MULTICAST,PROMISC,UP> mtu 1500 qdisc fq_codel state DOWN group default qlen 1000
    link/ether brd ff:ff:ff:ff:ff:ff

networkctl
IDX LINK             TYPE               OPERATIONAL SETUP

I didn't find solution for this... Add an IP address manually did'nt bring the interface up.

Thanks !

Re: [Solved] eno1 no carrier

Plug the cable in.  Seriously.

What are the status of the link LEDs on you NIC?  Have you access to the router? What are the status of its Link LEDs for your port?

Re: [Solved] eno1 no carrier

Yes, of course the cable is plug. The leds are off. I tried it with multiple cables, with multiple switch/routeur.

It works fine with others computers.

Re: [Solved] eno1 no carrier

You would be astonished how often it is the cable     I am bothered that the link lights are off.
What happens if you boot from the install media or a different operating system?

Re: [Solved] eno1 no carrier

I can imagine
I just tried to boot from a live system. I have the same problem.

My laptop is a Dell one, and I have no ethernet when I plug it on the docking station (I repeat that i'm sure about the cable ).

edit : I checked the bios configuration, the NIC interface is enable.

Have you tried rolling back those packages to check whether it is definitely a software problem?

Re: [Solved] eno1 no carrier

Well, I downgraded systemd and linux kernel but there is no change...
It seems like a hardware issue, but the problem appears with the docking station too. Any idea ?

Re: [Solved] eno1 no carrier

The problem persist after a BIOS upgrade.
Next step is to put my SSD in  another laptop (if I can find one).

Re: [Solved] eno1 no carrier

I put another SSD in the laptop. The problem persist. I will send it back to after sale service.

Many thanks to both of you for your ideas.

Re: [Solved] eno1 no carrier

when I plug it on the docking station

...

Does the notebook have an integrated RJ45 slot?

Re: [Solved] eno1 no carrier

Have you checked your bios/firmware setup for any option about blocking access to the network port? It's a huge coincidence that all ethernet ports stopped working.

Re: [Solved] eno1 no carrier

Yes, I agree it is really strange, but i updated the BIOS. The ethernet interface is enable.

Re: [Solved] eno1 no carrier

The dock is probably only a relay for the integrated NIC.
What chip is that actually (lspci -v) and (grep dmesg) does it load some firmware?

Re: [Solved] eno1 no carrier

You are right, only one driver (e1000e) is loaded when the laptop is plugged or not.

Re: [Solved] eno1 no carrier

what model is your laptop? have you checked that it is not blocked by some combination of keys?

Re: [Solved] eno1 no carrier

What happens if you reload the module and what is the power state of its PCI device?

Re: [Solved] eno1 no carrier

It was a Dell e7450. Dell just changed my laptop, so my problem is solved, I guess.
