I have just turned on my laptop and my Wi-Fi is not available! I cannot see my Wi-Fi settings and turn it On/Off by the top bar menu, as you can see in the screenshots below:
I have fully updated Ubuntu 20.04.2 with kernel 5.8.0-48-generic installed alongside Windows 10. The first time that I used Ubuntu my Wi-Fi worked pretty well.
I have searched many times, but couldn't find any solution for this problem.
I have collected some information about my Wi-Fi by the following script and paste the output here:
