After the upgrade the Wireless Network Card no longer works so I'm using Wired until that can be sorted out.

Details as follows:

sudo lshw -class network
  *-network UNCLAIMED
       description: Network controller
       product: Wi-Fi 5(802.11ac) Wireless-AC 9x6x [Thunder Peak]
       vendor: Intel Corporation
       physical id: 0
       bus info: pci@0000:02:00.0
       version: 29
       width: 64 bits
       clock: 33MHz
       capabilities: pm msi pciexpress msix cap_list
       configuration: latency=0
       resources: memory:df000000-df003fff

I think this was working after the upgrade but there were issues with some packages and I was requested to run command "sudo apt-get install -f" and this found Obsolete packages. I was requested to run "sudo apt autoremove" and perhaps all my issues stem from this.

I tried reinstalling Intel packages but still no joy.

See errors in:

Kernel in use as follows:

Also tried reinstalling Linux firmware:

Combination of these got me back in. I'm assuming the update of the kernel was required.

sudo apt-get update
sudo apt-get install linux-image-`uname -r`
sudo apt --fix-broken install

Updated kernel:

uname -r
6.8.0-41-generic

cat /etc/os-release 
PRETTY_NAME="Ubuntu 24.04.1 LTS"

You can run

sudo dmesg | grep iwlwifi

to learn more about the specific error.

Like you, I had futzed with reinstalling the firmware and linux-module-extras for my kernel version. But, when I finally broke down and followed the advice in the error message (which seemed overly manual) it worked.

My error message:

[   21.053604] iwlwifi 0000:00:14.3: Direct firmware load for iwlwifi-9000-pu-b0-jf-b0-46.ucode failed with error -2
[...]
[   21.055296] iwlwifi 0000:00:14.3: no suitable firmware found!
[   21.055300] iwlwifi 0000:00:14.3: minimum version required: iwlwifi-9000-pu-b0-jf-b0-30
[   21.055303] iwlwifi 0000:00:14.3: maximum version supported: iwlwifi-9000-pu-b0-jf-b0-46
[   21.055307] iwlwifi 0000:00:14.3: check git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

The solution was based on this post. I will try to provide more details pertaining only to what I think is your issue.

Notice that it states which versions are acceptable. I had those. But "error -2" loading them. So I cloned the repo mentioned and copied the max supported version over the existing one.

git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp linux-firmware/iwlwifi-9000-pu-b0-jf-b0-46.ucode /lib/firmware/

The, most people will tell you to restart. If you're sick of that, you can reload with modprobe.

sudo modprobe -v  -r iwlwifi
sudo modprobe -v iwlwifi

The first line removes it, the second reloads it. The v flag is to make it verbose because I like chatty tools. :)

It should be working. Rerun

sudo dmesg | grep iwlwifi

After the old error, you should see a happy message along the lines of

[ 1117.810409] iwlwifi 0000:00:14.3: loaded firmware version 46.7e3e4b69.0 9000-pu-b0-jf-b0-46.ucode op_mode iwlmvm
[ 1117.839047] iwlwifi 0000:00:14.3: Detected Intel(R) Wireless-AC 9560 160MHz, REV=0x318

I hope this helps you and good luck!
