I can't understand which drivers I have to install. RTL8111 or MEDIATEK 7961 for wifi. or upgrading kernel to 15 may solve this.

uname -r
5.11.0-27-generic

after a lot of time of searching updating kernel fixed my issue. From 5.11 to 5.13. The instructions are here. Also with download third party options and download updates (while installing ubuntu) with connected ethernet also helped me with installing WiFi.

sudo apt-get update
sudo apt-get dist-upgrade
