Ubuntu 18.04 Wifi network issue

Hi Everyone,

Need help on Ubuntu 18.04, can someone help me in suggesting any google group to fix it.

Hp Laptop with Intel® Core™ i5-4200M CPU @ 2.50GHz × 4, I have updated my Ubuntu from 16.04 to 18.04 all was fine initially and updating my software as I get the updates. From past one week my wifi was dropping all of a sudden and then from past couple of days wifi itself is not detecting in my ubuntu. I have tried few solutions after googling but did not fix. Can you kindly help me how can I fix it.
