Network applet doesn't work

[fulalas]

What are the requirements for the network applet to work?

Currently I can see the icon in the panel and click on it, but the wifi toggle doesn't do anything, I can't see any network available, etc. Nothing shows in the terminal. Using NetworkManager terminal applications work though.

Built from epoch on PorteuX (Slackware based) which has no systemd.

Some hardware need bcmwl-kernel-source drivers to be installed to discover Wi-Fi.

May be helpful to share the network card and any kernel logs relevant to it.

[fulalas]

I don't think this is kernel related. If I boot into any other DE it works, including DEs using the original nm-applet.

Is it possible this is issue is happening because cosmic-settings-daemon is not running?

[mmstick]

It should be running for applications to get configuration notifications, and for certain settings to be applied from configurations.

[fulalas]

So how can we find out what's happening? I'm suspecting this is due to some missing dependency, but I see no error, no warning, nothing.

I basically have the same problem: While I'm already connected to a network when logging in via gdm, the network connection stays, but cosmic-applet-network won't show an icon but a blank space and when selected just shows "Airplane mode" (slider), "Wi-Fi" (slider) and "Visible Wireless Networks". However neither can I move the sliders nor do any networks show up.

The weird thing is I have 3 users on my machine, the user created during install runs the applet fine. The other two users experience the problem, thought one of the users is member of the very same groups as the first user (sys, network, power, sudo, lp, wheel). Every NetworkManager applet under gnome and KDE works fine on all users.

In journald I get

I run Manjaro with kernel version 6.10.5-1-MANJARO #1 SMP PREEMPT_DYNAMIC, same issue regardless of building from sources through AUR or installing via binary packages.

@fulalas To answer your question. You need Network Manager installed. Have you verified that the NetworkManager.service is running? systemctl status NetworkManager.service I am on Arch Linux and I was having the same issue. I installed Network Manager, enabled the systemctl enable NetworkManager, and systemctl start NetworkManager After doing that the wifi applet worked and the visible networks were available to establish a connection.
