Wifi not working after update to 22.0.5

Hello y’all. I have a problem I hope people here can help me with.

I work on a Thinkbook 14s Yoga G2 IAP with Manjaro KDE.

Thursday I realized that my wifi wasnt working anymore. After Investigating I think it might have to do with an update I made on monday. Monday everything was working and since I was just using the laptop a little more after the update I didnt directly restart (which is what I otherwise usually do).

While digging around trying to figure out what was wrong I found the following regarding my network controller:

00:14.3 Network controller: Intel Corporation Alder Lake-P PCH CNVi WiFi (rev 01)
	Subsystem: Intel Corporation Wi-Fi 6 AX201 160MHz
	Flags: fast devsel, IRQ 16, IOMMU group 8
	Memory at 601d174000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: <access denied>
	Kernel modules: iwlwifi

Whith some other command which I fail to recognize right now I found something saying that the driver for said network controller is “N/A”, which leads me to believe the update somehow uninstalled/unmapped my wifi driver. Now while I’m not completely helpless with computers I feel like drivers are well over my head and I dont want to break more things than I fix. So I’m asking for help here and hope you have some ideas.

For further clarification:
I dont see any wireless networks anywhere anymore and everything points me to believe my wifi isnt working at all.

The update on monday has the following log (even though I think the office suite probably doesnt matter…)

I also think the controller isn’t set up at all since ip link gives

1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
2: enp0s13f0u2u1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
    link/ether f4:a8:0d:27:c7:8a brd ff:ff:ff:ff:ff:ff

without mentioning something wireless (I believe lo here is from the docking station while enp is the wired connection).

Have you tried with kernel 6.1 LTS or 6.2 yet?

yes, try different kernels, and then downgrading linux-firmware

Okay it is working now with the 6.1 LTS kernel. I was so afraid of touching kernel stuff and yet it was so easy - thank you very much!

Only sad thing now is that it works but I still dont know what the problem was ^^But I’ll take that. Thanks for your help! :slight_smile:
