Please any one help me to resolve this issue.


You have to turn on your computer with windows and you should turn on your wifi. After that, restart your computer with ubuntu. Then it should work.


I also recently have the similar type of issues with ubuntu 16.04. For development its better to use standard version like ubuntu 14.04 LTS if you recently installed. Anyway you need to be fight to get rid of it try to run this once ::

sudo service network-manager restart

It will restart the network service and if its already drivers installed it may work.
