ath10k_pci failed the read device register, device is gone

[supple elbow]

Hello everyone. This is my first post to this server. Firstly I want to take a minute to thank all of you for your dedication to the project and time that you spend helping others. Especially in a wold here time seems to be short. I have home assistant installed on an old DELL laptop I have kicking around. I have made some bios changes ad version 17.1 "latest at this time" seemed to have some issues loading bluetooth. So I disabled that and it seems to be fine. The problem I have is with WIFI. The error in the title seems to present after,,,,, Lets ball park 6 hours. This kills the network and the only fix is to reboot the HAOS.

If I look in
/usr/lib/firmware/ath10_k/QCA6174
I see 2 directories HW2.1 Feb 10 137k and hw3.0 Feb 10 279kb

I managed to find a full driver set at https://packages.debian.org/testing/kernel/firmware-atheros
The drivers I downloaded are from this DELL KB article https://www.dell.com/support/kbdoc/en-au/000144425/killer-wireless-firmware-update-guide-for-ubuntu-systems

I have FTP the dirve set to the OS in /mnt/data/supervisor/addons/local/temp/QAC6174

I want to try a different firmware than what is installed on HAOS but the problem is that the file system is read only. I have tried to boot with a ubuntu USB and force mount the file system on nvme0n1p7. I can only mount the file system in Read only mode. It willl not mount as RW.

As this HAOS is on a laptop. I have keyboard, Screen and can login directly as the root user.
Does anyone have any ideas on how I might complete this task?

I did a quick google. It looks like the drivers on some versions of that WiFi card can be unreliable. If its happening after 6 hours it could be some form of power management trying to turn the WIFI off to save power. There may be some form of setting in the BIOS for ASPM (Active State Power Management). If there is you could try turning that off to see if it stops the card going to sleep, its possible there is more than one option for this so some research may be needed to figure which option may be affecting the card. Depending on the laptop, I had an old Dell one years ago where the Wifi was unreliable and I replaced the WiFi chip with an Intel one which was much more reliable. This is going back some years, but depending on the laptop may also be a possible solution depending on which laptop model it is and how much effort is required to replace the chip, you should be able to check on Dell's page for your machine's Service code/Serial number what Intel wifi card would have been an option, kind of a nuclear option but may give you a lot more stability. I think applying the drivers into HassOS is going to require you to rebuild the image, as you mentioned its mounted read only so replacing the files without doing so will likley be very difficult
