WiFi adapter not getting enabled

I purchased Dell Inspiron 5370 a week back.

And I faced wifi connectivity issue.

To explain further wifi adapter disables on it's own and I cannot see any wifi networks available. On again n again troubleshooting it the problem still persists.

I even tried going to network and connections in control panel and ENABLING wifi adapter manually.

But still nothing.

I m so disappointed. New laptop and m stuck with this issues whenever I sit to do some of my work.  :(
