How do I get the wifi on my computer to work?

The wifi on my MSI PS42 laptop stopped working after an Ubuntu Base update. Only ethernet functions at present. Problem has not fixed itself after updating from 21.04 to 21.10.

Looked into additional drivers in software & updates to check for drivers, none are available.

Network card model is Intel Corporation Cannon Point-LP CNVi

sudo modprobe iwlwifi && sudo dmesg | grep iwl

This will be a provisional answer as further investigation continues.

First, if this is a dual-boot with Windows, please disable Fast Boot: https://wireless.wiki.kernel.org/en/users/drivers/iwlwifi#about_dual-boot_with_windows_and_fast-boot_enabled

Next, let's try a driver parameter:

sudo -i
echo "options iwlwifi uapsd_disable=1"  >> /etc/modprobe.d/iwlwifi.conf
exit

Reboot and check:

sudo dmesg | grep INIT

Reference: https://bbs.archlinux.org/viewtopic.php?pid=1918191#p1918191 (NOTE: Although there are several possible driver parameters discussed here, I'd prefer to try only the most likely one at a time.)

Finally, soft blocked:yes usually indicates that wireless networking is not enabled in Network Manager. Please use Settings to enable it.
