since yesterday I'm facing the problem that I can't use W-LAN or Bluetooth with my Laptop device. I was running several commands from other threads (see below), but none was helping. At the end I booted the system with a different Kernel I had installed and finally the W-LAN worked again.

Today, the yesterday's issue appeared again but this time I'm unable to figure out how to get along. Any help is appreciated.

Here, the error output looks similar to the one I've got, but execution of the commands rmmod and modprobe did not help. This did not help either.

System OS: Ubuntu 20.04.3 LTS with Kernel 5.4.0-89-generic x86_64

My device's network controller: Intel Corporation Wireless-AC 9462

lspci -kvnn | sed -n '/Network/,/^$/ p' gives some more details:

Update

Following Pilot6 advice to install HWE it still does not work. However the error message is more precise this time:

uname -r outputs 5.14.14-051414-generic.

sudo dmesg | grep iwlwifi outputs the same output as before.

Update 3

Following @unbi-rabka answer did not solve the problem.I still do not have wireless connection.

sudo dmesg | grep iwlwifi outputs:

[    3.373741] iwlwifi 0000:00:14.3: enabling device (0000 -> 0002)

Also I tried to install a brand-new installation of Ubuntu-18.04 alongside my current installation. But it did not help either.

I just had the problem recently (August 2022) after years of no problems with an Intel 3160 wlp2s0. One of the incremental upgrades to 20.04 I suspect. I solved it by upgrading to 22.04

i use kubuntu 20.04 and Wifi 6E AX210

i have same issue after update os, so i try this on my pc and its works

mv /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm /lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm.bak

after rename, you must restart your pc

For anyone else arriving here looking for a solution, I've had a similar issue with a laptop on 20.04, with an Intel 9461 adapter.

It appears to me to be a kernel/driver/firmware mismatch. I was able to resolve by upgrading the linux-firmware package. To do this, I looked at this page to see the available versions of this package for 20.04 and newer releases.

I downloaded the newest, but that did not change the problem, so next I tried the next-newer than what is available on 20.04, which is from 21.04 (hirsuite) and is version 1.197. This fully resolved the problem, and should not be broken by an update, assuming any linux-firmware updates to 20.04 maintain their version scheme. Any updates to this package in the focal repository would be versioned 1.187.x > 1.187.29, which would be greater than the current version, but always lower than 1.197...

Here is a link to the mirrors page for a direct download to version 1.197 of the linux-firmware package.

EDIT: Scratch that! Looks like wpa-supplicant.service was restarted during the apt installation of 1.197, and it just happened to do so when a working firmware file was the only one present in /lib/firmware/. Subsequently, downgrading to version 1.187 is giving a working combination.

I've pinned that package to the 1.187 version and now it is actually working, even after a reboot.

This is what I did on 20.04:

user@computer:~$ cat /etc/apt/preferences.d/linux-firmware-iwlwifi-on-5-13-0-fix 
Package: linux-firmware
Pin: release a=focal-updates
Pin-Priority: -10

Package: linux-firmware
Pin: release a=focal
Pin-Priority: 1001
