ethernet

[gloomy crest]

Hi all. I need to configure the Internet on Arch Linux during installation. I have a wire. I'm new. My Internet device displays in ip link.

[glass obsidian]

what's the issue then ?

[gloomy crest]

what?

[glass obsidian]

You don't need to configure anything if you are using wired connection.

[gloomy crest]

Why then doesn't it work?

@glass obsidian

[glass obsidian]

What's the issue exactly ?

are you able to ping google.com ?

[gloomy crest]

not

[craggy hollow]

they still need a network daemon

do you have one installed?

most common setup is using networkmanager with systemd-resolved as the dns resolver

networkmanager has an internal dhc client to setup ethernet cables that are plugged

@gloomy crest

[gloomy crest]

What to do? I'm ready.

[craggy hollow]

.

[gloomy crest]

what?

[craggy hollow]

install networkmanager, enable the service and setup systemd-resolved as the dns resolver

[gloomy crest]

I'm installing...

I can't install anything without internet

@craggy hollow

[craggy hollow]

ooh
ahhh

so you're still in the install iso?

[gloomy crest]

yes

[craggy hollow]

this hints to possibly missing driver or firmware for your ethernet adapter in the arch iso

[gloomy crest]

Hmm, what should I do then?

[craggy hollow]

can i see output of ip a
and ip link

[craggy hollow]

okay

1. it's not a driver/firmware issue, so that's fine
2. your router/switch didn't automatically asign an ip address to your computer

does your router/switch have or not have dhcp?

also show systemctl status NetworkManager

[gloomy crest]

????

[craggy hollow]

do this first

[craggy hollow]

damn, not there
how about systemctl status systemd-networkd

[gloomy crest]

@craggy hollow

[craggy hollow]

wait, i missed that
the link state is down

[craggy hollow]

in here

is the router/switch the ethernet is connected to active
or is the cable connected to the router/switch?

[gloomy crest]

yes

Everything works great on my windows 10

[craggy hollow]

ip link set enp4s0 up

try this

[gloomy crest]

My friend left, he didn't want to

I helped him install arch

[glass obsidian]

yeah, but it shouldn't be an issue in the installer while using wired connection.

[craggy hollow]

yeah
found out the iso makes use of systemd-networkd for automatically setting up wired connection

but it seems that their link is down for some reason

[glass obsidian]

@gloomy crest have you tried unplugging and re-plugging the cable.

[craggy hollow]

ip link set enp4s0 up
```could also help

but this is not active anymore
