  • Please [edit] your question and add output of lspci -knn | grep Net -A3; rfkill list terminal command. – Pilot6 Dec 28 '20 at 11:55

  • Have you checked [settings]+[power saving]? Then as I remember there is a check box to turn off each to save power. I checked those my first days of use. – user28523 Dec 28 '20 at 09:15
  • There is WIFI in power Saving in which it says wifi will be turned off when battery is less.It's checked already and when i uncheck it aeroplane mode gets swiched on . – xy examp Dec 28 '20 at 09:56
  • Please someone help on this , i am still not able to resolve this . – xy examp Jan 16 '21 at 11:27

Get this Intel utility which tests compatibility. https://downloadcenter.intel.com/download/26735/Intel-System-Support-Utility-for-the-Linux-Operating-System

It will tell you whether any Intel based card is compatible. NO AX200 chip-based card is compatible. I've tried 2 now. Canonical really screwed the pooch with the 20.04 release.

I don't know the kernel version that you're using. You can check it with the command:

uname -r

However, updating the kernel to version 5.12.6 has worked for me, even though it just solves the Wi-Fi problem.

If you want to try it, you can follow the instructions in this answer:

The simplest set of instructions I always used for kernel upgrade / downgrade are by ubuntuforums.org user by the name of lykwydchykyn (url modified by me for this post):

  1. Go here: http://kernel.ubuntu.com/~kernel-ppa/mainline/

  2. Download 3 (maybe 4) debs to a folder somewhere:

    linux-headers-VERSION-NUMBER_all.deb
linux-headers-VERSION-NUMBER_amd64.deb
linux-image-VERSION-NUMBER_amd64.deb
linux-image-extra-VERSION-NUMBER_amd64.deb   # if available

  3. Install the debs with whatever package manager front-end you use (is gdebi still around?), or use these commands:

    cd /path/to/folder/where/you/put/the/debs
sudo dpkg -i *.deb

  • By the way, i just did another thing that is give a command "sudo apt install linux-generic-hwe-20.04" in my terminal then "reboot". It would install linux kernel version 5.13.0-25-generic. and now, wifi and bluetooth worked. – habib Jan 18 '22 at 09:11
