All network devices suddenly disappeared 24.04.3 LTS

Asked by NguyenTanThanh

At noon today, Ubuntu notified me of a system update and I proceeded to install it. After the update, my computer completely lost Wi-Fi and Bluetooth connections, and the touchpad also stopped working.

I am using an Asus G14, 2021 version, with Ubuntu 24.04.3 LTS. I have used chat and searched further and ran the following commands:
When checking the kernel with the command uname -r, I got the result: 6.14.0-36-generic.

I tried running the command:

sudo modprobe -v iwlwifi

but received the error message:

ERROR: ../libkmod/libmkmod-module_insert_module() could not find module by name='iwlwifi'
ERROR: could not insert 'iwlwifi': Unknown symbol in module, or unknown parameter (see dmesg)

At the moment, I do not know how to fix this and would like to receive detailed guidance on how to resolve the issue. I just installed this operating system 2 weeks ago, so I am not very familiar with it. I would greatly appreciate any help.

Thanks Jeremy, after updating it booted linux using kernel version 6.14.0-36-generic, and caused an error. I fixed it successfully by using kernel 6.14.0-35-generic. Thanks for taking the time to look into my error

Booting into a previous kernel is not a permanent solution (not a good one anyway)

See bug 2115148

Make sure you have headers metapackages installed:
sudo apt install linux-generic-hwe-24.04 linux-headers-generic-hwe-24.04

Thanks! Rolling back to kernel 6.14.0-35 instantly brought back my Wi‑Fi and Bluetooth. Next, I’ll install the HWE headers so that it doesn’t break again with future updates. Really appreciate everyone’s quick guidance!
