No wireless connection after system update

Hey,

after an update, I cannot connect to WiFi anymore, since my connector is not recognized anymore.

My connector is:

lspci -knn | grep -A3 Net
0000:00:14.3 Network controller [0280]: Intel Corporation Alder Lake-S PCH CNVi WiFi [8086:7af0] (rev 11)
	Subsystem: Intel Corporation Device [8086:4090]
	Kernel modules: iwlwifi
0000:00:15.0 Serial bus controller [0c80]: Intel Corporation Alder Lake-S PCH Serial IO I2C Controller #0 [8086:7acc] (rev 11)

It is neither hardblocked nor softblocked:

rfkill list                                                                                                                                                                                   
0: dell-wifi: Wireless LAN
	Soft blocked: no
	Hard blocked: no
1: dell-bluetooth: Bluetooth
	Soft blocked: no
	Hard blocked: no
2: hci0: Bluetooth
	Soft blocked: no
	Hard blocked: no

I updated my system and I’m running:

uname -a                                                                                                                                                                                      
Linux <laptop name> 5.15.112-1-MANJARO #1 SMP PREEMPT Wed May 17 11:11:32 UTC 2023 x86_64 GNU/Linux

I tried to download the newest firmware and copy it into /lib/firmware and restarted the computer to no avail:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
cd linux-firmware
sudo cp iwlwifi-*.ucode /lib/firmware

lsmod | grep iwlwifi:

iwlwifi               458752  0
cfg80211             1081344  1 iwlwifi

Does anyone know what the problem could be or which information is required to find the root cause of this problem?

I really appreciate any help you can provide.

Cheers,
Alex

Hey, I looked through the forums here and at the bottom of a post here I found a solution that worked for me (I installed kernel 6.3). Sorry that I can’t include the link, it doesn’t let me. I assume it is because my account is new.

# List available kernels
mhwd-kernel -l
# Install new kernel
sudo mhwd-kernel -i linux63
# Reboot
shutdown -r now
#Check kernel version
uname -r

Now my WiFi is detected again.

Cheers,
Alex
