According to this article, the command hcitool dev should need to
deliver a list of Bluetooth devices. I get this non-result - though I
have been using Bluetooth at the same laptop, when it ran on Kubuntu
22.04.4. LTS:

The keyboard key combination FN and F5 at my Lenovo Thinkpad X230 should
need to switch on and switch off WIFI. However, nothing happens. I keep

Info at page 47 of the hardware manual related to Lenovo Thinkpad X230: FN+F5 ....Enables or disables the built-in wireless networking features.
Notes: If you want to use Fn+F5 to enable or disable the wireless features, the following
device drivers must be installed on the computer beforehand:
• Power Management Driver
• On Screen Display Utility
• Wireless device drivers
Question - is there a way to get such drivers and to get them working at
Kubuntu 24.04 LTS?

SUMMARY SO FAR:
WIFI and Bluetooth works at Kubuntu 22.04.4. LTS. However, it does not
at Kubuntu 24.04 LTS. I have been using both LTS systems at exactly the
same laptop with the same BIOS settings.

WHAT TO DO NEXT TO GET BACK WIFI AND Bluetooth?
===========================
Apparently, both WIFI and Bluetooth got hard blocked after a fresh install of Kubuntu 24.04 LTS at my laptop.
Kubuntu 22.04.4. was a fresh install of early April, at the same laptop, with the same BIOS settings. In the BIOS, there is no password or security lock. It's simply default stuff.
I have no clue what to do next.

Cannot enable WIFI & Bluethooth at fresh install of Kubuntu 24.04 LTS.
«Hard blocks» or something else?

Bug description:
Cannot enable WIFI & Bluethooth at fresh install of Kubuntu 24.04 LTS.
«Hard blocks» or something else?
Update from the bug reporter, Bas Roufs, Tuesday 7 May 2024, at about
12.30 CEST, Mook, near Nijmegen, The Netherlands:
For:
Expert users and developers of Kubuntu and/or other flavours of
*Ubuntu, who know about WIFI and Bluetooth - especially in connection
with the package rfkill.
Cc.:
KDE Experts.
Previous versions of this report I have submitted here:
https://bugs.kde.org/show_bug.cgi?id=486368
KDE experts who have replied me there, emphasised that the issue needs
to be resolved «downstream», in my case at the level of *Ubuntu.
INTRODUCTION.
============
@ Kubuntu and other *Ubuntu 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 and other Ubuntu flavours in our case. That's why, i finally
file this bug report.
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 so far to get the WIFI enabled. The same applies for
Bluetooth. Neither GUI approaches, nor command line solves anything so
far.
Ticking the box for enabling WIFI is not possible. The same applies for Bluetooth. Check the screenshots I send along with this bug report.
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.
Here, I go through the screeenshots that I send along this bug report:
1. Mouse at WIFI connection corner right down under. I indicate the
place to look at by means of a red arrow.
1a. Focus at mouse pointer at WIFI connection corner right down
under.
2. Enabling WIFI not possible. The red arrow and the mouse pointer
point at the box that cannot be ticked with a view to enabling WIFI.
2a. Detail - Enabling WIFI not possible. A more detailed look at the
corner where the red arrow points at the box that cannot be ticked.
3. Bluetooth disbabled. The red arrow and the mouse pointer both point
at the area where bluetooth should need to be enabled.
3a. Impossible to get Bluetooth enabled. After the click indicated by image 3, I end up here.... The button aimed at enabling Bluetooth cannot
be toggled. This button is being indicated by the mouse pointer and the red arrow.
A few terminal checks so far do not solve the problem. However, more
info comes to the surface. Take a look at the next paragraph.

STEPS TO REPRODUCE
=================
1. Check my screeenshots attached to this bug report. See also above, «THE PROBLEM IN BRIEF».
2. Command line checks summarised here - see here above, «COMMAND LINE
OUTPUT REPORTS.»,
What I expected to happen.
=========================
Enabling WIFI should need to be possible via either command line, the graphical approach or both of them.
In early April 2024, only some weeks ago, I have fresh-installed Kubuntu 22.04.4 LTS at exactly the same laptop, with the same SSD, the same hardware specs and BIOS settings. At that configuration, WIFI worked out of the box, simply correctly. Bluethooth worked also - however, with hiccups and interruptions. I expected similar results after fresh-installing Kubuntu 24.04 LTS. More info about my laptop: see here below, «Software and hardware system info».
what happened instead.
========================
So far, it has not yet been possible to enable WIFI and Bluethooth. At the GUI screenshots I send along with this report, you can see the check boxes that CANNOT be ticked with a view to enabling WIFI and Bluethooth.
The terminal checks summarised here above, produce some useful info.
However, they do so far not bring any solution that helps to enable
WIFI and BLuetooth.

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
bug report at KDE, https://bugs.kde.org/show_bug.cgi?id=486368
> 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.

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 apparently SOME bluetooth in the
system.
Now, I check whether bluetooth is running or not.....
bas at Camino:~$ systemctl status bluetooth

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:

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.
SUMMARY AND CONCLUSION: HARDWARE ISSUES OR SOMETHING ELSE?
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
For both WIFI and Bluetooth, command output results shared in this
report seemingly point at hardware issues, hard blocs, etc.On the
other hand, at exactly the same laptop along with the same BIOS
settings, I WAS able to work with those techniques along with Kubuntu
22.04.4 LTS - WIFI out of the box, BLuetooth with some hiccups and
interruptions. Terminal output reports shared here above, 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 and interruptions. BIOS settings
at my Lenovo X230: NO «security» enabled. No BIOS password!
Provisional conclusion: I am really not sure whether «hard blocks» or
any other hardware issues are the core issue.
