Ethernet not configuring (stuck on Getting IP-configuration)

Murqs · 2025-11-23 16:00:03

Hello!

I'm a student, who often moves between home and school dorms with my laptop that is on arch linux. I hadn't had any problems for 2 months until my ethernet in the dorm building stopped working. After trying the wifi (which is on the same internet), i got a connection. Meaning its unlikely a DNS issue. Using the same cable i have connected to my roommate's pc, which is on windows and it got a connection meaning its unlikely an issue with the cable itself or the internet port. Upon putting the cable in my laptop, it recognizes the device, but i won't get an ip. But this is only the case in the dorm building. At my home, using the same laptop and ethernet cable my connection works. Meaning it shouldn't even be a problem with my network interfaces. This has confused me as i can't even find the source of the issue. Best i can think of is that either my laptop or the school's dormitory has a firewall of some kind that is rejecting connection through cable, which sounds kind of absurd. I'd be really grateful if anyone would be able to at the least find the source of the issue so i could continue troubleshooting and looking for solutions.

I've also went on my arch ISO install usb, booted into it and tried getting connection. It did not. Once again confirming it should not be a problem in my network interfaces.

I'll send my journalctl for networkmanager down below, that seems to be connected to the issue:

Please edit your post to use [ code ] [ /code ] tags for command output , see https://bbs.archlinux.org/help.php#bbcode .
(It will improve the readability a lot)

Best i can think of is that either my laptop or the school's dormitory has a firewall of some kind that is rejecting connection through cable, which sounds kind of absurd.

It's not unusual for school internet to be very restrictive for 'unknown devices' , sometimes using identification methods that only work through gui tools.

Install ethtool when you do have a connection.
As root / with root rights run

ethtool enp7s0 > enp7so.txt

and post the content of that file.

NetworkManager for me the perfekt fountain of troubles and horror. I use 3 lines of my script and everything is perfekt. Managed by me and Kusnetsov.

Thank you for pointing the out, I'm a first time user and was unaware i could do that.

ethtool enp7s0 > enp7so.txt

Running the command outputs nothing.
Thank you for replying.

Outputs nothing, as in nothing in the file? Or just nothing in the terminal?

Murqs · 2025-11-24 18:43:13

There is nothing in the terminal, i am unaware of the file's location

You should probably have some clue what a command does before running it.

A page for you to read in order to understand what the ">" of the command you ran was supposed to accomplish.
