Cannot connect to internet after fresh install

Fallenalien22 · 2016-03-21 22:04:54

This is my first time installing arch linux outside of virtualbox. The install went smoothly. I rebooted my system and took out my live usb. When I booted back in, I had no wired internet connection. I googled around for a bit and found this:

systemctl enable dhcpcd@eth0.service
systemctl start dhcpcd@eth0.service

`The first command ran with no problems. The second one hangs. I checked the logs with `journalctl -xe`. That gave this:

...sys-subsystem-net-devices-eth0.device: Job sys-subsystem-net-devices-eth0.device/start timed out.
-- Subject: Unit sys-subsystem-net-devices-eth0.device has failed
-- Defined-By: systemd
...

Sorry I didn't include more of the logs, I had to type all that out from my other computer across the room.

Is your interface actually called eth0?

Don't google around: read the networking page on the wiki.

What happens if you just run (as root) dhcpcd

If it does not work, post the output here

I tried that. Got confused.

That seems to have worked. I got this output:

dev: loaded udev
no interfaces have a carrier
forcked to background, ghild pid 344

Thanks for your answer. Is the `no interfaces have a carrier` thing normal?

How did you install Arch? Did you use the Beginners' Guide? Is the networking section in the guide also too confusing?

You will need to answer this before you can make your network connection work correctly with systemctl.

No I used the installation guide. It is working fine now.

Did you figure out what your ethernet interface is called?

....no, that's a module name.

See https://wiki.archlinux.org/index.php/Ne … vice_names

Also, if you have trouble comprehending Arch wiki articles, perhaps a do-it-yourself distro like Arch isn't the best choice for you?

Usually I'm pretty good ad understanding the wiki. My problem here was I needed to run back and fourth between my two computers which was very annoying. I wasn't really reading in depth because I wanted to get online. I'm not too new to arch and I absolutely love the AUR.

So would it be enp0s25?

Arch Wiki wrote:

Current NIC names can be found via sysfs or ip link.

What is the output of "ip link"?

Possibly. All the information you need has been pointed out for you, you should be able to identify the device from that information.

Don't be be a help vampire.

Nope. That is probably your root cause.

Generally (but not always) that means the cable is not plugged in. You did check that, right?
Are the link lights on on the Ethernet port on your computer? On your router?
