INTRODUCTION.
============
@ the KDE experts who have dealt with this bug report:

A few words about the status of this bug.....
I do respect your wish to NOT «reopen» it. However, the qualification
«resolved» is simply not right - the bug is far from resolved. That's why,
I have changed the status of the bug to «reported» instead of «resolved».
However, as you suggest, I am sharing now this bug «downstream». It is not
possible, according to you, to solve the issue at the level of KDE.
«Downstream» means in my case: experts and experienced users of Kubuntu -
especially those who deal with WIFI and Bluetooth. I have already started a
conversation with a few amongst them about this issue. However, before
sharing this report more widely amongst Kubuntu experts and users, I need
to make this report more complete. That's why, I have added some extra
screeenshots as well as this 3 May update.
I need to add here two things more. First of all, it has become clear to me
that at my system, there is a similar problem with Bluetooth. That's why, I
deal with it in more detail in this update.
Finally - terminal reports indeed do point at «hard blocks» for both WIFI
and Bluetooth. Also a few Kubuntu expert users I spoke with so far, think
in the same direction, which I understand. On the other hand - Only a few
weeks ago, I have been working with Kubuntu 22.04.4 LTS at exactly the same
laptop with the same hardware and the same BIOS settings. Then, WIFI worked
out of the box and Bluetooth with some hiccups. I am really not sure
whether «hard blocks» are the core issue. More about this here below in
this paragraph.....

@ Kubuntu expert users.....
After checking the settings related to WIFI (and Bluetooth), I ended up
filing a bug report at KDE:
https://bugs.kde.org/show_bug.cgi?id=486368
According to the feedback I got from KDE experts after doing so, the
problem is real. However, those experts say it cannot be solved at the side
of KDE. It needs to be solved «downstream», so at the side of Kubuntu in
our case. My question in this context: how and where exactly can I file a
bug report in such a way, that it will be read and dealt with by Kubuntu
expert users who deal with WIFI and Bluetooth?
A complete update I'll publish here in a few hours.
THE PROBLEM IN BRIEF.
====================
So far, I do not manage to get WIFI enabled by the useful steps at a fresh
install of Kubuntu 24.04 LTS, at this laptop:
Lenovo Thinkpad X230 i5, along with 4 GB RAM, 250 GB SSD. A quick internet
search clarifies me that I am not the only one who deals with this problem.
I do work now with wired internet. However, this wired connection does not
help me to get the WIFI enabled. Ticking the box for enabling WIFI is not
possible. The same applies for Bluetooth. You can see it at the screenshots
I have sent along with this bug report:
https://bugs.kde.org/show_bug.cgi?id=486368
That's why, I have looked for methods to get both WIFI and Bluetooth
enabled via the command line. I do get useful info like that. However, so
far, I do not manage to get WIFI and Bluetooth enabled. Here below, I share
with you a command line output report.

STEPS TO REPRODUCE
=================
1. Check my screeenshots attached to the bug report at KDE.
It's about the graphical check down under - fruitlessly trying to tick the
box to enable WIFI or the one to enable Bluetooth.
At each screenshot, you can see a red arrow pointing at a WIFI or Bluetooth
check box that cannot be ticked.
2. Command line checks summarised here - see here above. See also the two
links for more info.
OBSERVED RESULT
==============
Both checks did NOT end up in enabling WIFI.
EXPECTED RESULT
==============
Enabling WIFI should need to be possible via either command line, the
graphical approach or both of them.

WHAT IS THE CORE ISSUE? HARD BLOCKS AND/OR SOMETHING ELSE?
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++
On Wednesday 1 May 2024, a comment came in about this passage in my report:
> bas at Camino:~$ rfkill list
> 0: tpacpi_bluetooth_sw: Bluetooth
> Soft blocked: yes
> Hard blocked: yes
> 1: phy0: Wireless LAN
> Soft blocked: no
> Hard blocked: yes
This is the comment I point at:
«(...)
If it is hardblocked, it cannot be enabled in software. E.g., see
https://askubuntu.com/questions/98702/how-to-unblock-something-listed-in-rfkill
Unfortunately this seems like a downstream configuration issue and I would
suggest asking for help on the distribution forums.

I get this point. I gonna ask for advise at two Kubuntu forum. I'll point
there at this bug report. If some useful advise comes in, I'll share it
also here.
More about Bluetooth.
---------------------
Here below, I carry out some checks recommended in this article:
https://community.spiceworks.com/t/how-to-verify-bluetooth-using-linux-command/961891
bas at Camino:~$ bluetoothctl -v
bluetoothctl: 5.72
bas at Camino:~$
No error report so far - there is SOME bluetooth in the system.
Now, I check whether bluetooth is running or not.....
bas at Camino:~$ systemctl status bluetooth
● bluetooth.service - Bluetooth service

Apparently, it is running, however, with some complications. How to fix
them? Can anybody help with this?
Now, I try this.....
bas at Camino:~$ sudo systemctl start bluetooth
[sudo] password for bas:
bas at Camino:~$
No error report here.
Now, I try again this command:
systemctl status bluetooth
The result I get is exactly as above.
Now, I gonna check whether or not all required packages have been installed:
sudo apt list --installed | grep blue
bas at Camino:~$ sudo apt list --installed | grep blue
[sudo] password for bas:
WARNING: apt does not have a stable CLI interface. Use with caution in
scripts.

Apparently, everything needed has been installed.
Now, I look at the «bluetooth adapter» and connectivity issues.
sudo hciconfig hci0 reset
bas at Camino:~$ sudo hciconfig hci0 reset
Can't get device info: No such device
This is weird....This points at some hardare issue? On the other hand... at
exactly the same laptop with the same specs, I DID work with Bluetooth.
However, it was not reliable. There were hiccups.
By toggling FN + F5, I tried to get Bluetooth and or WIFI working.... But
the test «sudo hciconfig hci0 reset» delivers the same non-result.
Any conflicting Bluetooth related services running? I try this command....
sudo systemctl list-units | grep -i bluetooth
bas at Camino:~$ sudo systemctl list-units | grep -i bluetooth
bluetooth.service loaded active running Bluetooth service
bas at Camino:~$
Apparently, there is one process running. But I still cannot «enable»
Bluetooth.
No clue what to do next to get Bluetooth running. Can anybody help me with
this?
HARDWARE ISSUES OR SOMETHING ELSE?
+++++++++++++++++++++++++++++++++
For both WIFI and Bluetooth, command output reports seemingly point at
hardware issues, hard blocs, etc.On the other hand, at exactly the same
laptop, I WAS able to with with those techniques - WIFI out of the box,
BLuetooth with some hiccups.
I hope to get together more answers from now on.
