Facing Error - "DNS Address Could Not be Found"

Hi there, 

Recently I updated windows to windows 10 everything is fine with it except one error which occurs every time when I surf the Internet actually when I use the internet it works for only 3-4 minutes and sometimes lasts for 10 minutes and after this, it suddenly shows an error DNS Address Could Not be Found. 

I didn't face any error before Updating Windows 10. Please help me to fix this error as soon as possible share the correct way to solve this.

Any input will help.
