Install the latest UEFI firmware for the machine, and then re-run the tests.

I do not mind that it is a useful suggestion in general and should be 
followed, but I am curious if it has ever helped you in specific cases 
of intel wifi cards.

My experience with it is far from being positive. Some days firmware 
crashes are rare, some periods of time they happen every minute. I have 
not identified reasons, so results of debugging attempts would be 
unreliable. Sometimes restarting of the router helps. That is why I 
suspect that access points around may affect my connection.

My impression is that version of driver in backports kernel is more 
stable, however in addition I downloaded firmware newer than 72.

There are enough discussions, bugs, various suggestions concerning 
parameters of kernel modules. Downgrading firmware did not helped me. I 
have not noticed any improvements from disabling power save mode.

Some links:
https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_platform_noise
https://bugzilla.kernel.org/show_bug.cgi?id=205123
https://bugs.debian.org/1026906
https://wiki.debian.org/iwlwifi

The relevant line from

     lspci -nn

output should help to identify wifi adapter model.

I am not trying to dispute your suggestion, I had a hope to get a data 
point with a success story.

To be precise concerning packages, it is firmware-iwlwifi 
(src:firmware-nonfree). Even unstable currently have a year old package, 
so for experiments it is better to take files from an upstream git 
repository. It requires kernel upgrade since the range of supported 
firmware versions is hardcoded.

Hi Max.

Sorry to go off the list.

In 2006 I was doing sysadmin work for the Nuclear Energy Institute. NEI
performed a hardware refresh, and supplied ~50 employees with new Dell
laptops. I don't recall the model, but they had integrated Intel wifi. The
laptops would connect via wifi, and disconnect after about 10 minutes. Dell
support told us we needed to update the BiOS or UEFI. It fixed the problem.

About 6 months ago, I bought a used Intel NUC model NUC5PPYB. It was
running Fedora 39 at the time. A `sudo reboot && exit` over SSH would cause
the machine to hang on shutdown. I had to walk over to the machine and
cycle the power. The NUC had UEFI from 2015. I updated to the 2022 version
of the UEFI (version PYBSWCEL.86A.0081.2022.0823.1419), and the hang on
reboot was fixed. Apparently there was some problem around ACPI.

So the data point is unrelated to 72.daa05125.0 cc-a0-72.ucode or to 
some other recent intel wifi card. It was my fault that I was not clear 
enough asking for details.

I think, 2 decades ago balance between platform firmware and per-device 
firmware loaded by drivers was different. A few years ago I have seen 
recommendations of intel wifi cards as reliable ones.

In bookworm, driver spits a warning that it can not find a firmware 
file. Actually it is not available and it is impossible to just download 
the "missed" file. It is intended for debugging and one has to request 
it and then has to send gathered data to intel developers. It is 
discouraging from my point of view.

My bad. I was talking about the manufacturer's UEFI firmware; not a
linux-firmware package.
