I am unable to connect to the WiFi. My laptop is a dual boot with Windows 11 and Ubuntu 20.04. The WiFi is able to connect with the Windows 11, but not with the Ubuntu.

As per ChanganAuto's request, the results of running lspci -knn | grep Net -A3 are:

0000:00:14.3 Network controller [0280]: Intel Corporation Device [8086:a0f0] (rev 20)
    DeviceName: WLAN
    Subsystem: Intel Corporation Device [8086:0264]
    Kernel driver in use: iwlwifi

I also attached an image here.

As per Chili555's request, the results of running sudo dmesg | grep iwl are:

Hey Chili555, I tried as per your directions. Firstly disabled fast boot (from BIOS as well as the Windows 11[Fast Startup], As I was unable to figure it out which one). Then later on I attached Ethernet and ran sudo apt update && sudo apt install -y iw and detached the Ethernet and rebooted. And when I ran this nmcli device wifi list command, it was all blank enter image description here

And also would like to provide you this additional information after running the command lshw -C network. It shows DISABLED for Wireless Network enter image description here

Here is the rfkill list all:

And here is the sudo dmesg | grep iwl:

Reinstalling the NetworkManager resolved the issue. i.e. by sudo apt-get reinstall network-manager.

Why I tried reinstalling: Firstly I tried nmcli which showed that the SW Plugin is missing for the wireless. This helped me to narrow down things to check with the network manager.

For all those who commented, thanks for your precious time and helping me out in finding a solution. Special thanks to Chili555

Restarting network-manager service worked for me. Note that now it is renamed to NetworkManager

sudo service NetworkManager restart
