i have tried to re-install the networkmanager from the pacmanager and after reinstalling it the same problem appears

i dont know how to fix it, i hope that you can help

2

Do you have other network services running at the same time?
systemd-networkd maybe?

If networkmanager is failing, how are you typing this? xD

3

systemd-networkd: command not found
i’m using another laptop to write this topic

4

sudo systemctl status systemd-networkd.service

And while you are at it, run:

sudo systemctl status systemd-resolved.service

Edit
Oh well, I’m going to go :joystick: so I might not be available for a while.
But look into those things, or if you have some other network manager running.

https://wiki.archlinux.org/title/Systemd-resolved

Maybe this will give some insight:

According to the log file, your network manager crashes.

<error> [1702566749.5963] bus-manager: fatal failure to acquire D-Bus service

Could you please also try to look into:

  • /etc/NetworkManager/NetworkManager.conf
    :footprints:

when i hover the mouse cursor on top of the networks icon in the bottom bar it showd: networkmanager 0.9.8 required, found .

that file is empty
i tried to change the name of /etc/NetworkManager/ to networkmanager1
then i re installed the networkmanager and it creaded a new NetworkManager folder. and the result is the same

8

can you show us the output of:

cat /etc/NetworkManager/NetworkManager.conf
9

Maybe take also a look into

whether it shows similarities or whether the links there will help you.

mine is not empty :innocent:

cat /etc/NetworkManager/NetworkManager.conf
# Configuration file for NetworkManager.
# See "man 5 NetworkManager.conf" for details.

None of them is up to date :wink:

i cant update the kernel without wifi now
that article helped me a liitle:
i find that i have installed ConnMan
so i think there may be a conflict between connman and networkmanager? how to figure that this is the case? and how do i connect to the net with connman instead of networkmanager? do i need to delete one of theme?

that topic have a similare problem:
https://forums.gentoo.org/viewtopic-t-1087700-start-0.html
it says: It appears DBus is rejecting access to NetworkManager:

12

Problem fixed
i removed connman and restarted and now the wifi is working again.
so, if i want to use connman so what do i need to do?

13

from ARCH-Wiki :smiling_face_with_three_hearts:

Before [enabling](https://wiki.archlinux.org/title/Enabling) `connman.service`, ensure any existing [network configuration](https://wiki.archlinux.org/title/Network_configuration) is disabled.

ConnMan comes with the [connmanctl(1)](https://man.archlinux.org/man/connmanctl.1) CLI, there are various [#Front-ends](https://wiki.archlinux.org/title/ConnMan#Front-ends) available.

https://wiki.archlinux.org/title/ConnMan

Category:Network managers - ArchWiki :point_up_2:

So next time please share with us what you tried to do before it broke :wink:
