Linux firmware loads the incorrect iwlwifi ucode

Hello Everyone,

I am having issues with my wifi connection. My wifi drops sometimes for no reason and I have to manually restart netctl-auto. Sometimes I have to do multiple times and sometimes I have to do only once. Then again it can drop at any time. Below is the logs from `dmesg`

I tried many suggestions given by others since this issue looks very common. But unfortunately nothing seems to solve this issue. Therefore I did more searching and I found out this support article from intel.com. This article is last reviewed on 02/10/2021 and it suggests that the ucode for my wireless device is iwlwifi-7265-ucode-25.30.14.0.tgz. I download this package and saw that it contains the iwlwifi-7265D-14.ucode. The current firmware used by my laptop is iwlwifi-7265D-29.ucode. So i decided to downgrade my ucode according to the support article. This doesn't work at all. When I check the `dmesg`, output is as follows

[   11.551110] iwlwifi 0000:03:00.0: Direct firmware load for iwlwifi-7265D-29.ucode failed with error -2

[   11.616409] iwlwifi 0000:03:00.0: check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

According to the `dmesg` output ucode iwlwifi-7265D-14 is out of range of minimum version and maximum version. I am no expert of the kernel but I cloned the project as suggested in the logs and I saw in the file WHENCE a list of ucodes but I don't see iwlwifi-7265D-14. Do you think that if I use the iwlwifi-7265D-14, this issue will be fixed or is there any way that I can make the kernel load iwlwifi-7265D-14?

Thanks.

Re: Linux firmware loads the incorrect iwlwifi ucode

"This table contains only the first official firmware version released, which is only guaranteed to work with the kernel version specified in the table. To get the latest version for newer kernels, use the firmware git tree instead."

It's not saying that you need 14, it's saying you need at least 14.

Hi, just for information and hope it will usefull, on my fedora (no tested on arch yet) laptop, I have make my IWLWIFI 7265D stable by downgrading to the firmware IWLWIFI-7265D-22. I remove firmware 29 and 27.
