Network not working after installation... [SOLVED]

VoidTheGamer25 · 2026-06-26 11:33:30

I installed networkmanager with pacman during the installation (and more packages) but when i boot into the system there is no connection. Doing ip addr show shows the lo thingy and the ethernet connection, but it doesnt put an IP. it also says DOWN in red letters, which ig means its not working.

I read the wiki page for network management and did the steps it said to enable the module but it didnt work. I have so many questions... (Why is the network not working, why does my user void not have a home directory, why cant i even go back to the root user, why dont i have a GUI....)

I am sorry if i didnt post the exact outputs of the commands but i cant even connect with SSH so i cant copy the outputs...

Im off to a rough start :c

What exactly does it say?

$ ip link show eth0
$ ethtool eth0
$ nmcli device show eth0

(Replace eth0 with your ethernet interface name).
Also

$ nmcli -g UUID connection show | PAGER='' xargs -I{} nmcli -p connection show {}

Also

pacman -Qs firmware
lspci -nn

Linking a photo of your screen (don't embed huge images) is better than a vague description or even a manual transcript.

why does my user void not have a home directory

You forgot -m ?

Please avoid shopping list threads and maybe re-consult the wiki on your problems.

for the first commands you sent and

For the second commands you sent. Also, I did do -m when creating the account.

Also this isn't supposed to be a shopping list post, I was just complaining, which is something I do very good.

Also I'm guessing enp2s0 is the interface.

Also I'm guessing enp2s0 is the interface.

Which is why you should have substituted eth0 for it.

There's no trace of a wifi device, the ethernet device is there (intel firmware is installed) and has a carrier.
What do you (intend to) use to obtain a lease (since it's not NM) - dhcpcd?

I did do -m when creating the account.

If that's true, are you mounting anything into /home ?

I literally did. You can see in one command I forget to change it, so then I re-enter the command with the correct interface.

What do you (intend to) use to obtain a lease (since it's not NM) - dhcpcd?

What the hell is that? I have no idea of what a lease is. Excuse my ignorance, but I have been looking at the wiki for network management and I haven't seen that.

Also just forget about the user problem, that's for later.

Edit: a "lease" is when your router gives you an IP address (or you statically configure one it will accept)
This is typically done automatically via dhcp

You say that is typically done automatically... then why isnt it automatically done? How do i fix it?

i have tried the dhcping command and it says it doesn't exist...

And the wiki isnt helping that much either, i dont know what to do...

seth · 2026-06-26 13:03:29

dhcp gets you the IP automatically but you'll still have to run it meaning you've to install *something* that does that as https://wiki.archlinux.org/title/Instal … l_packages pointed out

W/o internet you'll have to usb-walk a package to your host or install it after chrooting from the iso so you can use its internet connection.

VoidTheGamer25 · 2026-06-26 13:16:30

In the link you sent it says packages needed for networking like a network manager or a standalone DHCP client. That link leads to the table of network manager thingies. But I already have one, as I said in the first post I have NetworkManager, and the problem is that it isn't working! I don't know what to do to get it to work!

seth · 2026-06-26 13:19:08

Did you https://wiki.archlinux.org/title/Networ … orkManager ?

find /etc/systemd -type l -exec test -f {} \; -print | awk -F'/' '{ printf ("%-40s | %s\n", $(NF-0), $(NF-1)) }' | sort -f

Aaaand I'm stupid. I had to turn NetworkManager on. Sorry for wasting your time.

to maybe give you a hint for future topics: often it's not just enough to install some packages - but for them to do something usually some service has to set enabled and started
as for your other questions:

Why is the network not working, - solved
why does my user void not have a home directory, - have you given "-s" to useradd?
why cant i even go back to the root user, - does root has a password? have you installed something like sudo? have you edited sudo config to allow your user to become root? have you given "-G wheel" to useradd?
why dont i have a GUI - well, same as here: you usually have to enable the display manager (gdm, sddm, plasmalogin) - just installing a DE does only waste space
