Re: LXQt nm-applet missing

I thank you
libstatgrab allowed me to add the network monitor applet.

But the applet does not let me configure my network, nor the wifi

personally I'd just wipe the lot and start again from the sound of your pc, but never having the wi-fi working even on a live boot on the jan .iso) kind of flags a firmware issue for your card to me - do you know what it is?
You can see above (reply #6) I built the firmware for it , and I think it is installed correctly. But I am open to the idea I did it wrong.
I also see it flash, as it does when the driver is working on ClearLinux.

But I could be wrong.

I am loath to wipe and redo, as I have several configurations like SSH that I did not keep track of, and am sure to miss on a reload.

Personally, i keep a cheat sheet when installing/configuring a new install, otherwise those commands that don't work begin to get lost in the ones that do - that way if and when i need to reinstall, i can just copy and paste down the list and it all goes smoothly and quickly too (and cleanly!)
About my third reinstall I started doing that, but did not keep it up with all the changes.

But if that is the only way to fix my wifi, I guess I'll have to.

Is there a known set of things I should back up to make recovery easy?

i really don't think that is the problem - my reasoning for that is that I just live booted the stable .iso (albeit for dinit) and nothing required to add to the wi-fi network for this thinkpad, so I'm assuming the only difference is just the init, which shouldn't make a difference, and the chip, for which mine is a realtech 8822.    But when you live boot, you cannot connect to wi-fi from the live boot, so i'm pretty much out of idea's.  Sorry.

I am not arguing that netmanger CANNOT work.

It is obviously misconfigured/missing a component/whatever.

I just figured if I could replace it with something that works, then, it would work.

okay....on a live boot, can you connect to wi-fi?   If the answers "no", its not a little widget thats the problem but  points more to firmware etc - otherwise this or indeed 2 other machines I tried this afternoon would not be able to connect either without adding "a missing component" too either.   As an aside, seriously, i can't remember the last time i installed anything linux without verifying wi-fi connections first for obvious reasons!

I do not know much, but I do not see how my wifi could work on a live CD?

If one needs to build a driver for the wifi to work and install it on a standard install, then, i assume, i would need to do that with for the live CD.
How do i do that with a live CD?

I mean another option is to have them include the drive on the live CD, but I do not see that happening.

You mean you tried it on machines that had wifi drivers that were included with the live CD?

Did you try it on any machines that did not have the correct wifi driver on the live CD?
But I tried it. i downloaded a weekly, 30May, and booted it. The panel crashed right out to a error message and blank screen on boot.

I happened to have a 06Mar, which booted, but it did not have a driver. I started to update it, then i realized, any updates were useless.

I just assume I need a hardline, will have to update, and then fight with the wifi.

good, glad you see it - besides i was only trying to help and steer you away from an alternative to nm which would be fruitless  because you have another issue behind it.   maybe the aircrack you install didn't completely uninstall, maybe the updated firmware ver is the answer - either way, there's a selection of 4 for that chip, and we know one certainly doesn't work, one is orphaned so that leaves two - the time taken on this thread is a lot longer than the time to do a clean install, twice if necessary, just saying.   And with that, I shall leave it.  Goodnight,  G

I've skimmed through this thread and unless I'm mistaken I've not seen dmesg (or the kernel.log) mentioned.
Code: [Select]
sudo dmesg
will show you all the the devices setup at at boot and since.
Code: [Select]
sudo dmesg >~/dmesg.txt
will place a text file with it all in your home dir for easier searching.
If your device is a dongle remove and reinsert and you should find some messages relating to your device right at the end if you run dmesg again.
Post them.
Also search dmesg for any errors, especially relating to firmware.
For the time being consider downgrading to the most recent lts kernel
Code: [Select]
sudo pacman -Syu linux-lts linux-lts-headers
When the kernel goes up a point release, as it very recently did, this can sometimes cause compile and other issues with 'out of tree' drivers. Which from my skim I guess yours is ?

sudo dmesg >~/dmesg.txt

sudo dmesg >~/dmesgreinsert.txt

@gripped if dmesg has no errors, is there a need for downgrading the kernel?

There should be some messages with the actual driver / kernel module setting up the device.
With a device name like wlan0 or wlp5s0 or fairly similar.
Code: [Select]
ip link show
will list all your network devices
Code: [Select]
cat /proc/net/wireless
should list your wireless network devices (I haven't used wifi on my pc in years so no expert)
So the other posters are right, no working driver. You need to keep trying to build a working driver from the AUR and / or downgrade the kernel as I suggested until the above commands show a wireless network interface.
Any errors encountered post in full and be as detailed in the steps taken as you can.

Alternatively get a wifi dongle which is well supported by linux with an in kernel driver. Not saying you should. Just that it's an option.

wireless devices do show.
this dongle, as the github.com/morrownr/8812au-20210629 doc explain, allow dual devices. currently they are wlan0 and 1

Does this not support that there is a working driver installed?

lsmod shows it too, i think?

A driver at least. Hopefully working.
I'm surprised there's no mention of wlan0 (or wlan1) in the dmesg output. But there you go.

Let me have a think.
On my PC I use a wired connection with no NetworkManager or systray applets so can't help with that. But I used to use something terminal based to set up wifi on my Arch chromebook. Going to see if I can remember what it was. And what I use now. It did have lxqt on it but switched KDE. Only use it on holidays (so once in the last three years!)
