Issues between iwlwifi and Intel Cannon Point-LP CNVi Wireless Adapter

Hi!

Yesterday my wireless adapter stopped working out of nowhere, I wasn't doing updates, just using my notebook for work (attacched to a different wireless network, if it is relevant).
Since yesterday, the iwlwifi module crashes and the wireless interface does not show up.

If it can be useful, after the initial problem I searched the forums and found someone suggesting to add the intel_iommu=off kernel parameter, so I did and it worked again for other 10 minutes.
After that I experienced some system lag and wifi instability, then it died again and the kernel parameter had no effect anymore.

My kernel version is 5.8.5, a friend suggested to try the lts kernel as well (version 5.4.61) but I got the same problem with a different log.

This is the output of lspci, my notebook is a 2019 Asus Zenbook (UX333FN).

I am asking since similar issues are for older versions of the kernel and now marked as solved, which seems not to be my case.
I also found this https://bugs.archlinux.org/task/65638 which seems related to my issue.

Do you have any advice? Is there a way to rule out hardware damage?
Thanks

Re: Issues between iwlwifi and Intel Cannon Point-LP CNVi Wireless Adapter

I can confirm similar issue. Different card, no updates and did not gracefully woke up from sleep giving similar series of errors. Device was soft-blocked after crash, but had to reboot to unblock and get device working again. No issues in Windows.
