wireless networks "device not ready"

[stevef]

From https://www.intel.com/content/www/us/en/...eless.html

Intel® Wi-Fi 6 AX201 - Kernel 5.2 or above.

and confirmed on https://cateee.net/lkddb/web-lkddb/IWLWIFI.html
Suggests the hardware is supported in LL7 which runs kernel 6.8.

With LL7, the iwlwifi module detects the hardware and tries to load firmware
From the information provided, firmware 86.fb5c9aeb.0 so-a0-hr-b0-86.ucode is loaded, but there is evidence that it crashes resulting in symptoms of network DISABLED and wifi unavailable/not ready.

Checking this link
https://wireless.docs.kernel.org/en/late...gging.html#
suggests it may be appropriate to report the apparent firmware crash to Intel
Specifically this reference.

Firmware crashes

When the firmware crashes, you’ll see a message like this:

iwlwifi 0000:01:00.0: Microcode SW error detected.  Restarting 0x82000000.
[snip]
iwlwifi 0000:01:00.0: Loaded firmware version: XX.XX.XX.XX
iwlwifi 0000:01:00.0: 0x0000090A | ADVANCED_SYSASSERT

In this case, please copy the full dmesg output since there may be data before and after this message that can be helpful.

From Intel https://www.intel.com/content/www/us/en/...eless.html

Intel wireless firmware and drivers have a dependency on the Linux kernel version. Only specific versions of wireless firmware and drivers are guaranteed to work with particular kernel versions. We support use of the drivers only in the kernel version which the driver was a part of.

The inference is attempting to cross modules and firmware versions is impractical.

Searching for official bug reports doesn't give anything.
Searching for hacks to fix doesn't give anything authoritative.  There are plenty of rabbit holes for example,
This post
https://askubuntu.com/questions/1540879/...k-disabled
has the same problem - no fix

and although this post is about an AX211 it is marked as solved
https://forums.debian.net/viewtopic.php?t=159566
Unfortunately the OP on that thread deleted their posts, so all we see is the reponses and it is impossible to know what was done.
The suggested fixes in that thread were to
a)modify /etc/modprobe.d/iwlwifi.conf
b)upgrading to an experimental kernel
c)run rfkill unblock all

Without having the hardware available, I can't help progress.
I know you don't like the recommendations already offered, but other than them, you may want to report your problem to Intel (again) and then wait patiently.
