Does that mean “too many” services are tying to manage the same function (controling wireless card)?
Or I am wrong?
Shall I be concern (and what could I do)?

cat /tmp/journal | eos-sendlog

inxi -Fxxc0z --no-host | curl -F ‘f:1=<-’ ix.io

It looks like you are running NetworkManager and systemd-networkd. In most cases, you wouldn’t want both of those running at the same time.

Would you know how does it come ?
I mean, is it “default” when installing Eos? (this install is pretty fresh…and I “almost” didn’t change anything)

So I guess I have to get rid of systemd-networkd

Cheers!

edit: or shall i dump NetworkManager :upside_down_face:

Every EOS installation I have done has used NetworkManager, not systemd-networkd. That being said, I haven’t looked at it extensively or tried every DE option.

Did you enable systemd-netword and create the file /etc/systemd/network/20-wireless.network? :innocent:

1 Like

Not at all.

But there is indeed 2 files in /etc/systemd/network/
20-wireless.network
20-ethernet.network

Would it have been created on his own with a systemd update or something?y

edit: seeing the date of the files it has been created on install i guess… is it the same for everybody then?

I don’t have those files in my install but we probably installed off of different ISOs.

Did you do an offline install or online?

1 Like

Not totally sure which is which, but different ISO installs on my current machines do not have those files (nor do Garuda or Arch or!). Some kind of anomaly I guess!

1 Like

Weird :confused:

I did an offline install on this machine.

My setup is 2 x Arch, 5 x EnOS on 1 machine, and 3 x EnOS + 1 Arch and 1 Garuda on another. Mostly online install (to save updates) but 3 or 4 EnOS were offline for easier theming… The other distros on here aren’t systemd - so no way they would have them! :grin:

these files are from archiso structure and not needed on installed system…
you can savely remove both of them…

Could be that installation was not removing them…

So it could be you will have some more files not needed:
/etc/systemd/system/sockets.target.wants/systemd-networkd.socket
/etc/systemd/system/multi-user.target.wants/systemd-networkd.service
/etc/systemd/journald.conf.d/volatile-storage.conf

So i stopped and disabled systemd-networkd.service and systemd-networkd.socket, but the messages are still generated :confused:

.

Shall i remove that file too?

Does that mean I have to choose between iwd and wpa_supplicant?
(which one?)

And I don’t understand cause I stopped and disabled wpa_supplicant but it’s still running…

What do I miss?

I am not sure in this case but, generally speaking, units can be started by other units or be socket activated. It is possible that something else needs it and is starting it.

Since IWD is an alternative to wpa_supplicant, I suspect that you do need to choose.

Ok, so I choose to keep iwd over wpa_supplicant (why where they both there?)
To do so, i edited NetworkManager.conf (which for me didn’t show any settings)

sudo nano /etc/NetworkManager/NetworkManager.conf

adding

[device]
wifi.backend=iwd

Then I disabled (i learned how to do it for good ^^) wpa_supplicant service

sudo systemctl stop wpa_supplicant 
sudo systemctl mask --now wpa_supplicant 
sudo systemctl daemon-reload

I restarted iwd service, one might want to enable and start it

sudo systemctl start iwd
sudo systemctl enable iwd

and I restarted NetworkManager

sudo systemctl restart NetworkManager

On next boot the messages weren’t there (obviously cause wpa_supplicant doesn’t run anymore)
I wonder if that would have been the case if I did the countrary (keep wpa_supplicant instead of iwd), cause without the addition of wifi.backend in NetworkManager.conf the wifi wasn’t working at all.

I still wonder why both those services were present and running…

Edit:

So, wifi does connect now ULTRA fast, like really… but… 2 connections appears on the NetworkManager applet in the taskbar (name like my connection, but 1 and 2), and I only have one… and… I can’t disconnect ^^ at least from the NetworkManager applet in the taskbar, i get the error message (1) uid 1000 has no permission to perform this operation
I can obviously disconnect with the key on the keyboard.

archiso was needing some of the services … and they should have been removed on target (installed system) looks like on your install this part was not 100% doing this…
Offline install uses the same image to install system as it uses to run the live environment …

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.

So in the end (for now…?) I did the contrary, i got rid of iwd and kept wpa_supplicant (which take much longer to connect i must say)

I tried this and it works well on my end (on a Dell XPS 9380). Thank you!

I got also two SSID for my connection while selecting which network to connect to. Then I went ahead to WiFi settings in my system’s setting manager, removed them both without any glitch. At the next scan only one appeared to which I could connect without probleb.

I should add that on this system I don’t notice any significant difference in time for the connection to be established.

Cheers, erasing them and scan again is the way to go indeed :slight_smile:

Regarding the “time for connection” on my end it’s not more than a couple of seconds with wpa_supplicant, but it was instantaneous with iwd.
I might check iwd at one point for “fun” ^^
