Hi there,
My wifi adapter is missing (probably after the last update)

What could be wrong? Does it have to do with the latest linux-firmware upgrade as I see other wifi related posts recently?
Best, stahl

Maybe. Maybe not.

Firmware isn't even attempted, the module is loaded from the root FS (so not a case of "rebuild your initramfs")
There're quite some partitions and at least an ntfs one - is there a parallel windows installation?
The wifi NIC is on the same bus as a usb hub where a yubikey, a keychron keyboard and a logitech mouse are attached (usb3) - can you move those to another hub?
Last but not least, does the last update also include a kernel update?
x-ref, https://bbs.archlinux.org/viewtopic.php?id=298631 (exact same error, unresolved)

No.

yubikey is connected to the laptop, the rest is connected via a thinkpad usb-c dock. i don't know how to move them to another bus..
Last but not least, does the last update also include a kernel update?
not sure, probably yes.
I just tried with a arch linux from a usb stick, no luck either.
The problem exists with the dock attached or not.
I wonder if it is a hardware problem or is this ruled out when it shows up with lspci?

Means the controller responds on the bus, not that it works.
not sure, probably yes.
=> /var/log/pacman.log is gonna have a reliable opinion on this.
https://www.google.com/search?q="Detected+crf-id+0x3617%2C+cnv-id+0x20000302" has a considerable amout of hits, but they're all/mostly related to missing firmware
Can't find a correct rfid for crf id 0x617
is unique and nb.
Detected crf-id 0x3617
That looks eerily like somebody accidentally hit del somewhere…

thank you @seth!

actually the id changed after i rm -r /usr/lib/firmware and re-installed linux-firmware package and rebooted. at least
the id is now persisting:

i keep using a wifi-dongle for now and hope the issue will be resolved with a future update. of course i'm happy
to investigate further.

Probably more about the reboot than the firmware re-installation (the firmware isn't even looked for at this point)
Try to power down the system, remove the battery, get a cup of coffee, restore the battery and boot again.
Alternatively (if not possible or effective): are you ok trying to reset the CMOS (means you've to reconfigure your UEFI) - though if the firmware allows that, disabling the wifi, booting, restarting and re-enabling the wifi in the UEFI for the next boot might do.
And try some live distro (grml or so), but this looks like it's HW related. I don't think that ID should ever change.
Offline
I removed both the laptop battery and cmos battery, it didn't help. Also disabling and re-enabling wifi via UEFI didn't help.
Lastly I tried grml live ISO as you suggested which could not find the network card either.
I think it's a hardware problem, so I'll contact Lenovo Support now to request a hardware replacement.
