wired connection not working, no-carrier

Prezes48 · 2019-10-07 18:08:31

My wireless connection is working, but i can't estabilish wired one.
There is "no-carrier" message, but my cable is connected, and when i suspend my system
there is the diode shining above router's cable socket, but only then.
I have tried many things but nothing works for me.
Maybe someone will be able to help me with this issue.
Here are my logs

Hello, can you post output of:

dmesg | grep ens5f5

Also, did you double check your cable
Do the lights flicker on your ethernet port?

loqs · 2019-10-07 19:24:37

Please post the output of dmesg ungrepped. grepping output removes context https://bbs.archlinux.org/viewtopic.php?id=57855

Hello guys, thanks for the reply!

Sorry, this is the first time I feel that I really need help, so it's my first post here.
Here are dmesg logs: https://pastebin.com/jjPU2yE1

grepped output:

[   17.709554] jme 0000:05:00.5 ens5f5: renamed from eth0
[   27.671546] jme 0000:05:00.5 ens5f5: Link is down

My router's ethernet port light is on, but ONLY when I suspend my machine.
I tried another cable - the same story.
I can't check from live cd right now

[   17.357314] jme 0000:05:00.5: can't disable ASPM; OS doesn't have ASPM control

Does the system dual boot with Windows? If so is Fast Start Up disabled?

Prezes48 · 2019-10-07 21:09:46

It was dual boot with windows 7, but I formatted windows partition and now it's linux only.

The interwebz is full with complaints about this chip:
https://askubuntu.com/questions/1124300 … everything

sudo ethtool -s ens5f5 speed 100 duplex full

Prezes48 · 2019-10-07 21:37:56

Holy moly!

I'm so grateful @seth
Works like a charm
Thank you guys!

nb. that
a) this means you got no gigabit connection
b) the change is not permanent, you'll have to re-apply this w/ the next reboot, eg. using a udev rule: https://wiki.archlinux.org/index.php/Udev

Yeah I read your link from askubuntu
a) speedtest tells me that my download speed is 2x, so it's win
This machine is a toaster. I'm gonna change it in a few years and I'll remember not to buy JMC chip.
I have not disposed of it yet, because of sentiment only.
b) I'm on it right now
