[SOLVED] iwd service unable to connect to wifi

gitarthasarmac9 · 2020-08-02 05:27:02

After a fresh installation of Arch with KDE Plasma 5 desktop environment, I connected to my wifi using the GUI network manager available and was successful. But during installation, I had connected to the internet using the iwd service. So, post-installation after installing iwd with pacman on my computer, I followed the same steps I used to connect to my wifi during installation but it failed.

STEPS I followed:
1. Installed the iwd service
2. Started and enabled the iwd service.
3. Next I ran the comman

 iwctl

to open the interactive shell of iwd
4. Next I ran the command(HOME is my wifi network)

 station wlan0 connect HOME

The prompt asks for the passphrase, I enter it. But the immediate output is

Operation Failed

Below is the output of systemctl status iwd.service

You are running another networking service. Disable it, or you will have conflicts like this.

Sorry for the dumb question, but how do I know which other networking service is running?

jasonwryan · 2020-08-02 06:09:13

find /etc/systemd -name "*.service"

The following will give you a list of running "service" units:

systemctl --type=service --state=running

If you really don't recall which packages you have installed then you can look at pacman log to see what packages have been installed

cat /var/log/pacman.log

This is fresh install you said. Did you install the wpa_supplicant package?

https://wiki.archlinux.org/index.php/Wpa_supplicant

Be cognizant of the packages you install. Get familiar with systemd.

Okay, I got the point one doubt. I guess in my scenario iwd, NetworkManager and wpa_supplicant all 3 of them are running simulaneously. Is that creating the problem?
If they are then which of them should be turned off while using the other?

>> systemctl --type=service --state=running
UNIT                      LOAD   ACTIVE SUB     DESCRIPTION

wpa_supplicant.service    loaded active running WPA supplicant                       

LOAD   = Reflects whether the unit definition was properly loaded.
ACTIVE = The high-level unit activation state, i.e. generalization of SUB.
SUB    = The low-level unit activation state, values depend on unit type.

15 loaded units listed.

If you want to use iwctl you should stop and disable NetworkManager and wpa_supplicant.

But stopping NetworkManager will also disable Plasmas network management GUI, if you want to keep that but still use iwd instead of wpa_supplicant see: https://wiki.archlinux.org/index.php/Ne … Fi_backend

Okay got it, I disabled both wpa_supplicant and NetworkManager and connected through iwctl it worked, but sometimes it connects, sometimes it doesn't. I was tweaking a lot maybe that might affect it. Nevertheless, it worked and in my opinion, wpa_supplicant is much better in the backend instead of iwd. Thanks for the help guys!

I had the same problem. Please try the solution:
1. Edit Connections > Wired > Network name > Edit > IPv6 Settings > Method > Ignore/Disabled
2. Save and connect
