[SOLVED] Network is unreachable on a fresh install

I installed Arch on my secondary laptop, managed to get the internet running smooth for a day and then, all of a sudden wifi connection was cut. I noticed that I had both systemd-networkd and NetworkManager enabled so I disabled systemd-networkd and rebooted, of no avail.

nmcli device show wlan0

shows that the state is disconnected, I have no ipv4 ip address. Yet ipv6 has both a gateway and 3 routes. iwctl works alright, I can connect to wifi but ping 8.8.8.8 says "Network is unreachable". I couldn't see anything worth mentioning with journalctl -b.

I can only provide short snippets from the output as I have to type the output by hand. So please tell me what to look for in the outputs instead of asking for full dumps.

Also, booting from the live stick results in similar behavior and I have no ethernet connection.

You can redirect the output into files and usb-walk them to a system w/ internet connection or possibly use your phone for https://wiki.archlinux.org/title/Tethering

iwctl works alright

Don't run iwd next to NM, unless you're using it as NM backend, https://wiki.archlinux.org/title/Networ … Fi_backend

Post the output of

ip a; ip r

after supposingly connecting to the wifi and eventually your system journal is likely required.

Re: [SOLVED] Network is unreachable on a fresh install

Problem solved! I stopped and disabled iwd, connected with nmcli and got connected.

Thank you for you help once again, Seth!
