Unable to connect to ethernet

It works on my windows 10 partition.

Right now I'm connected over wifi, I hope that doesnt affect the results of my commands.

ip link gives me:

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000

I have docker installed if that helps, wondering if maybe it's interfering?

I believe my device for ethernet is enp4s0 but I don't know.

Tell me o arch wizards what spell I ought cast.

Re: Unable to connect to ethernet

Please wrap the output in "code" tags.
enp4s0 is your wired ethernet NIC and "NO-CARRIER" generally suggests a lack of "wire".

Other than that, please read https://bbs.archlinux.org/viewtopic.php?id=57855 and elaborate on "Unable to connect" - how do you attempt it, what are the error messages/symptoms etcetc.
As for "works on my windows 10", please see the third link in my signature.

As generic advice: try to connect via ethernet and dump the output of "ip a; ip r" and if you already wonder whether docker is interfering, stop wondering and check by getting it out of the equation.
