Hello, I was using MozillaVPN from the mozillavpn-git package from the AUR installed using yay. All of a sudden, the network hung so I turned it off. Then it won't connect again, with or without the vpn on. I tried rebooting but the networks not connecting. Then I tried uninstalling, nothing. Reinstalling, nothing. I tried logging out and resetting using the dev options menu, nooope. Now I'm stuck banging my head.
networkctl shows that the interface (enpXXX) is degraded and configuring. systemctl showed that initially only mozillavpn failed but after doing a failed-reset, nothing popped up there anymore; even after rebooting. machine is able to ping itself using localhost and hostname.local but no other devices on network. cannot ping 1.1.1.1. networkd config has only settings for name=enpXXX and DHCP=yes. starting up then killing mozillavpn didnt do anything.
using unbound as dns resolver, does not have networkmanager installed.
Sorry I couldn't get any direct output from the terminal, my computer won't go online kek.

You're somehow online to post and read this, right?
sudo journalctl -b > /tmp/journal.txt
(ip a; ip -r) > /tmp/ip.txt
Then usb-walk those files to the system w/ network access and post them eg. to https://0x0.st

ip -r didnt do anything for me so ip.txt just has ip a

Lil small update: same thing even on the arch install medium. degraded and configuring. Usually that doesn't happen. It also doesn't work with the debian install medium, which is definitely not supposed to happen. I literally cannot use my computer.
Not even Windows is able to access the network through it.

NIC is up and has a carrier but no lease.
Post your /etc/systemd/network/20-wired.network and try to stop/disable networkd and just run "sudo dhcpcd -dB"

[Match]
Name=enp12s0
[Network]
DHCP=yes
I don't seem to have dhcpcd installed
But going off of arch install medium,
it reads the lease
solicits DHCP lease
sends discover (xid 0x4f27adae)
spawned BPF BOOTP
solicits an ipv6 router
send the solicit multiple times
no ipv6 routers available
keeps sending discovers after
theres nothing in /var/lib/dhcpcd/* in the arch install medium
I tried using a usb to eth adapter and even that says degraded too.
Trying to use a static ip with networkd shows routable and configuring in networkctl.

Please don't paraphrase, https://bbs.archlinux.org/viewtopic.php?id=57855
In doubt link a photo of your monitor.
Install nmap, ( https://archlinux.org/packages/extra/x86_64/nmap/ - download and usb-walk it to the system) and see whether a dhcp server responds in the segment at all:
sudo nmap --script broadcast-dhcp-discover

Sorry about that, here is the output of dhcpcd and nmap from my installed system.

There was nothing like
Pre-scan script results:
| broadcast-dhcp-discover:
| Response 1 of 1:
?
There seems no dhcp server in that segment, if you're positive there's one active in your router, try to reboot the latter.

Nope, there was no output like that. Rebooting my router didn't work either. I went into the settings and saw that the router didn't even detect my computer. All other devices on ethernet worked just fine. I don't believe DHCP is the issue as the issue still persists even when I tried using a static IP with the following settings in 20-wired-network:
Gateway=192.168.2.1
Address=192.168.2.62
DNS=8.8.8.8
I set the IP in the router too. The computer can't even ping the router.

Did you try to re-plug/swap the cable?
Offline
Yep and yep, I think that the issue comes down to a fault with the VPN's kill switch somehow screwing with something pretty low level but I can't be too sure

Firewall.

Here ya go

I don't think it's the firewall though as other OS's also cannot connect to the internet (like windows and debian install media)

The issue was that a cable for the switch got unplugged. fml. I'm so sorry for wasting your time Seth. Thank you so much!
