This is a well-known bug #212371
Let's try the suggested fix:
Open a terminal by pressing Ctrl + Alt + T .
Run the following command:
sudo mv /usr/lib/firmware/iwlwifi-ty-a0-gf-a0.pnvm /usr/lib/firmware/iwlwifi-ty-a0-gf-a0.bak
Reboot to reload the drivers.
EDIT: It appears that periodic updates to the package linux-firmware
will install a new version of the offending file iwlwifi-ty-a0-gf-a0.pnvm
and so this process will need to be repeated.
Good Luck!
Alternatively, installing a newer kernel will fix this issue. In the bug report, users have specifically mentioned kernel 5.16
. Here are step by step instructions to install it.
Change the working directory to ~/Downloads
:
cd ~/Downloads
Download the kernel's .deb
files:
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-headers-5.16.0-051600_5.16.0-051600.202201092355_all.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-headers-5.16.0-051600-generic_5.16.0-051600.202201092355_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-image-unsigned-5.16.0-051600-generic_5.16.0-051600.202201092355_amd64.deb
wget -c https://kernel.ubuntu.com/~kernel-ppa/mainline/v5.16/amd64/linux-modules-5.16.0-051600-generic_5.16.0-051600.202201092355_amd64.deb
Install the .deb
files:
sudo dpkg -i *.deb
Satisfy the dependencies.
sudo apt -f install
That's it!
Good Luck!
