My laptop is HP PROBOOK with Ubuntu 20.04 installed. Last day my system kernel got updated to 5.13.0-27-generic and after that, I am not able to connect to wifi. The LAN connection is working fine but the wifi connectivity issue is there.
Following is the kernel detail -

Linux version 5.13.0-27-generic (buildd@lgw01-amd64-045) (gcc (Ubuntu 9.3.0-17ubuntu1~20.04) 9.3.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #29~20.04.1-Ubuntu SMP Fri Jan 14 00:32:30 UTC 2022

It used to work fine before taking the update, but suddenly after the restart, this issue has arrived.

I am not sure whether my drivers are missing or something went wrong with the wifi adapter.

In case of missing drivers where to get these drivers from and same with wifi adapter.

dkms status throws the following result
