ATH12K Driver Broke my WiFi Module

The ATH12K driver is unstable for use with the Qualcomm FastConnect 7800 Wi-Fi 7 High Band Simultaneous (HBS) Network Adapter.

It will break it eventually and if you switch back over to Windows (ew) then you will find the Windows HBS side of you WiFi doesn't work essentially making it a WiFi-6 module and not a WiFi-7 module as the 5G signal will sill work.

I blocked the person below so i can no longer see their comment which offered no help at all and was completely useless. However, a lovely person did comment saying i think i needed the Windows 11 Version 24H2 for x64-based Systems. This information which they provided is correct. You need to update to the KB5058499 update.

Once install you must go the Settings -> Network & Internet -> Advanced network settings -> Network reset. Then click on Reset now button and it will restore the original firm back on to the module. After the restart the module should work as expected.

Edit: This is a complete revamp of the post because i was high as hell when i originally wrote it. I hope this provide more clarity on the situation and details. Have a good day <3

After installing Arch Linux and some of it’s variations i can confirm that my WiFi 7 module, a ‘Qualcomm FastConnect 7800 Wi-Fi 7 High Band Simultaneous (HBS) Network Adapter’.
That sentence is incomplete. Did you mean to write something about the adapter there, or are you just confirming its official name?
The damage done to the module has left it’s WiFi 7 capabilities dead and Windows even rejects the 6G connection of the router.
How do you know the Wi-Fi 7 capability ever worked in the first place?
This is unacceptable and there is no warnings, compensation or support.
If software (the driver) actually caused permanent damage to the hardware, one might ask why the hardware/firmware allowed it. Perhaps the hardware maker should be compensating and supporting you?
Have you considered that this might be a firmware problem, and might be fixable?
Therefore i have had to begin using Windows as it is the only ISO which will now boot into the installer.
How in the world would a wi-fi adapter's lack of connectivity prevent you from booting an operating system's installer image?
Whatever it is you think you've confirmed, you might want to detail what you observed to reach your conclusion. (Once you're no longer so upset, that is. It's hard to communicate clearly when stressed.) Without details, nobody here will be able to help you.
I’m really upset by this and I now need to spend £360 on a new motherboard.
My condolences regarding the terrible experience. For what it's worth, the built-in wi-fi on some motherboards is a replaceable module, sometimes hidden under a hood. If yours is such a board, it's possible you could just swap out that part instead of buying an entire new board.
If you still decide to buy a new board, I suggest choosing one that's known to have support for whatever operating system you intend to use.

  It's a Qualcomm wifi 7 device, so it good chance the drivers never worked right in the first place Windows or Linux.
  Also OP, make sure you're on 24H2 of windows. Wifi 7 doesn't work well on 23H2 or earlier.
  
  Thank you I did check but unfortunately and i'm soprry to report it didn't resolve the issue. I've contacted the manufacturer for further support support.
