So I assume that you are using DKMS.
You have any error log?
Have you tried to install it again?

Yes, I am using DKMS as mentioned in the steps. After kernel update, I don't have any error and error log file, simply wifi is not showing up. Hence I am reverting to older kernel 5.13.0-52-generic using Ubuntu GRUB menu and wifi works and able to access internet.
