I run Ubuntu 20.04 and this script every day:

sudo apt update && sudo apt full-upgrade -y && sudo apt -f install && sudo apt autoremove -y && sudo apt autoclean && sudo snap refresh

After the end of every day, I power down my desktop. Maybe not the smartest script, but this is the first problem it's caused in 2 years or so... (I assume this problem is due to an update.)

This morning, when I booted, when I search for Wi-Fi in settings:

No Wi-Fi Adapter Found

I've been using the wireless adapters on my motherboard, which I'm assuming an update broke the drivers for. For now I'm using the sub-optimal powerline Ethernet.

Nothing shows up for sudo rfkill list all and the wireless device is not show when using ip a or ifconfig. (This also goes for Bluetooth, which is also on the motherboard and also enabled in the BIOS.)

Here's some partial output showing my wireless adapter being unclaimed.

$ sudo lshw -C network

My hunch is I need to reinstall a specific version of Linux headers or something, but honestly, I'm not too sure. Anyone have an idea of what could get my wireless device reclaimed and usable?

In our chat, we learned that the package linux-modules-extra-5.11.0-22-generic that provides the driver iwlwifi among many others, didn't get installed in your upgrade. I suggested that you do, while booted into kernel version 5.8 where the wireless does work:

sudo apt update
sudo apt install linux-modules-extra-5.11.0-22-generic

Upon rebooting into kernel version 5.11, your wireless is now working.

I also recommended:

sudo apt install --reinstall linux-generic

...because its dependencies and their dependencies include linux-modules extra.

If you have a dual boot with Windows, you might want to disable the Fast Startup in Windows.

See: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled

Here's what worked for me. First find out your kernel version:

uname -r

Note down the kernel version. (example: 6.5.0-44-generic), then run the following below (and replace the numbers with your kernel version).

sudo apt update 
sudo apt install --reinstall linux-generic
sudo apt install linux-modules-extra-6.5.0-44-generic

Reboot the PC and WiFi should be back.

If you are running Ubuntu in WSL, you need to disable Fast Startup in Windows, before the linux was telling me that the wifi is unclaimed. After disabling fast startup its working.
