Qualcomm Atheros QCNFA765 Module stopped working properly after attempted driver update

Question

I am running ubuntu 22.04.3 on Honor Magicbook 15. I have been experiencing random crashes latelty and was trying to look into them. I decided to start with checking my drivers. I wanted to check if my drivers were up up-to-date. Stumbled upon this post: How to download all required Ubuntu drivers. Following top answer's instructions I ran:

sudo ubuntu-drivers install   
sudo reboot

Afterwards, it looked like my laptop crashed or something went wrong. After a reboot I cannot connect to any Wi-Fi network. They are simple not displayed in "Networks" tab in bottom right corner.

Here are some things I have checked and believe could be useful: iwconfig output:

lo        no wireless extensions.
docker0   no wireless extensions.

rfkill list all:

0: hci0: Bluetooth
        Soft blocked: yes
        Hard blocked: no

lswh (only copied entries I found weird):

Any help would be greatly appreciated! Also, I can provide any additional information regarding this issue.

After hours of hitting the wall, I have finally figured it out.

Important note! I was completely unaware of what I was doing and why. I was simply replicating solutions I found online from people having issues close enough to mine.

My laptop doesn't have port for Ethernet connection and of course I don't own an adapter for that. So the first thing was to somehow get internet access on my computer.

It turns out that phones can share cellular data through USB alone. Here is simple guide for Android phones that I used to do exactly that.
I tried updating everything I could:
- sudo apt update
- sudo apt upgrade
- sudo apt install linux-firmware
I tried sudo modprobe ath11k where ath11k stands for the name of my driver.
I restarted my laptop.
I checked if the error was still present with dmesg | grep ath11k and indeed it was. At this point I realized that apparently my system could recognize my network module and it even saw that I have suitable driver for it installed, but for some reason, wireless connection interface of my network module still wouldn't appear on any command like ifconfig, iwconfig or rfkill list all.
The thing that I think made the difference (outlined in this post), run:
- wget http://mirrors.kernel.org/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.197_all.deb
- sudo dpkg -i linux-firmware*.deb - this one actually gave me an error, I don't know what's up with that.
I rebooted once again, losing all hope that was left.
Upon reboot I get greeted by working and already connected Wi-Fi. What a pleasant surprise! I think this whole experience once again taught me that with computers, and Linux specifically, the most important thing is not to give up. The solution is somewhere out there. You just have to keep trying.

Again I do not understand or know what most of these things mean and if they actually did anything for me or not, but I know for sure that after doing exactly this, it all worked out for me.
