WiFi is not working. Not sure how to fix it. I had same WiFi chip on my older PC where it worked by disabling fast boot. I did disable fast boot but no luck. I've done update.

How to fix it?

Some commands and output:

$uname -r
5.11.0-46-generic

$ lsmod | grep iwlwifi
iwlwifi               372736  1 iwlmvm
cfg80211              888832  3 iwlmvm,iwlwifi,mac80211


$ ls /sys/class/net
enp3s0  lo


$cat /etc/netplan/01-network-manager-all.yaml


Let NetworkManager manage all devices on this system

This command provides greater details around the hardware capabilities of specific adapters.

In the terminal:

sudo lshw -class network
