Hi,

Ive used KDE Neon for a few months on both laptop and desktop. I love it. However on my laptop every now and then I loose wifi. This didnt happen when I was running Windows. I do not have any third party drivers on my laptop. Its fairly new like last year model of a HP Spectre

Operating System: KDE neon 5.17
KDE Plasma Version: 5.17.4
KDE Frameworks Version: 5.65.0
Qt Version: 5.13.2
Kernel Version: 5.0.0-37-generic
OS Type: 64-bit
Processors: 8 × Intel® Core™ i5-8250U CPU @ 1.60GHz
Memory: 7,5 GiB of RAM

I run the software updates as soon as I see a new update - in discover.
Is there other things to update? Kernel? Im very new to linux so I dont know these stuff..
Kubuntu Driver manager says "your computer require no proprietary drivers".

Also I dont know where to find logs for this events..
Some people suggested using linux hwe updates to kernel and modules-extra. If this is recommended could someone please explain to a noob like me how to enable/install this?

Thanks!

Hi,
Please, open a terminalm execute the following command rfkill list and put the output.

You can also include the following outputs from the terminal:
rkfill list --> show whether your wifi card and bluethoot are blocked or not.
inxi -Fxxz --> the output show the wifi card you have installed
systemctl status networking.service --> this tell you whether the networking cards are running or not.
dmseg | grep Network --> the output show you whether any problem exist on the wireless connection
iwconfig --> show the status of your wireless connection.
ifconfig --> show the status of all your wireless and wired connections.

Hi,
You are right, I have missprinted rfkill and I see you have no blocked either your wifi or bluethoot card. Good job!

Network: Card: Intel Wireless 8265 / 8275
driver: iwlwifi bus-ID: 02:00.0 chip-ID: 8086:24fd

From the ifconfig output it seems that you have no problems
On the terminal put the output of the following command:
journalctl -g iwlwifi
The output of dmesg | grep iwlwifi should also be required.
sudo systemctl status NetworkManager

Also the output of the command lsmod to check whether the wifi card is working correctly.

HP Spectre x360 Convertible has a lot of problems with the wifi adapter. You could find helpful information here:
https://askubuntu.com/questions/868075/ ... untu-16-04

You can also try to install the propietary drivers.
May be you could do this form>

sudo apt-get install --install-recommends linux-generic-hwe-18.04 xserver-xorg-hwe-18.04
